The ARC 4 Analysis software guides step-by-step through a series of measurement points around the listening area ­ with ARC’s flexible placement options, the process will be done in less than 10 minutes and can be repeated for multiple pairs of monitors or listening areas.
Once the measurement process is complete, the correction is transferred to the ARC Studio hardware unit processor for latency-free, set-and-forget operation. From now on, the unit works completely standalone, while still letting switch between monitors and presets whenever desired.
Alternatively, without the hardware, the correction can still be used in any DAW by inserting the ARC 4 plug-in on the master bus.

2.1 ­ The ARC 4 measurement microphones
For the most accurate results, it is strongly suggested to use the included ARC 4 MEMS microphone.
However ARC 4 allows using any other measurement microphone you might already have, provided it comes with a calibration file (which is usually a text file provided by the manufacturer).
When using other measurement microphones, the very high accuracy ARC 4 guarantees when using the dedicated microphone cannot be ensured as it depends on the accuracy of the 3rd party microphone.

ARC 4
2.3 ­ The ARC 4 analysis application
The ARC 4 Analysis application is a standalone application that analyzes your speakers and room system and automatically calculates the best possible correction that will be applied later by the ARC 4 Plug-in and/or stored in the ARC Studio device.
The ARC 4 Analysis application works by sending test tones (usually called “chirps”) to your speakers while recording the signal captured in the room by the measurement microphone.
By measuring your room across a 3D space around the listening position, IK’s award-winning ARC technology creates a 3D snapshot of your room to identify and completely correct the dominant problematic issues, while maintaining the natural sonic quality of the monitoring system as if it wasn’t corrected.
You have the choice of going through a 21-point ultra-accurate measurement process or a 7-point quicker one. Both will sound great, the longer measurement is more adequate for fixed installations and permanent setups, while the shorter measurement is ideal for on-the-go or ad-hoc setups, making it possible to measure the room in less than a minute.
2.4 ­ The ARC 4 correction plug-in
This multi-platform plug-in is the ARC System 4 component that will apply the correction curve measured by the ARC 4 Analysis application to the monitoring system.
The ARC 4 plug-in should be inserted on your DAW’s stereo master bus or, when possible, on the monitoring bus.
Thanks to the ARC 4 plug-in included features, you can customize the setup for ideal performance no matter your preference.
2.5 ­ The ARC 4 Studio standalone application
The standalone application is designed to manage the setup of the ARC Studio hardware unit. Using the app, you can either have a “set and forget” software- less approach and use the application just the first time to configure the ARC Studio device or keep the device connected via USB-C to control every element of the correction from your desktop for limitless flexibility.

3 ­ Setup for Analysis
3.1 ­ What you need to analyze your room
To correctly analyze your room, you need: 1. The ARC 4 Analysis application. This is included in the ARC System 4 installer and works as a standalone
application. 2. A high-quality audio interface with at least one XLR microphone input with +48V phantom power. The ARC 4
MEMS Measurement Microphone or any other measurement microphone. 3. Microphone stand and XLR microphone cable.
3.1.1 ­ Audio interface requirements
To correctly analyze your room, you need a high-quality audio interface that can operate at 48 kHz.
On Windows, ARC 4 works exclusively with ASIO drivers. Make sure your audio interface supports this standard.
3.2 ­ How to set up for analysis
To properly capture your room analysis, you need to connect your measurement microphone to your audio interface and your audio interface to the speakers. Usually, you will already have the speakers properly connected, so you do not need to change anything on the speaker connections at all.
IMPORTANT NOTE: If you are using ARC Studio, make sure the correction on ARC Studio is OFF before starting the measurement process.
3.2.1 ­ Speaker connection
Make sure that your Left (L) and Right (R) speakers are connected directly to a pair of your audio interface outputs. If anything is present between your audio interface and your speakers (like a mixer, a monitor management system, etc.), check that their settings do not alter the audio signal in any way (e.g., no tone controls, no mono switch, phase reverse, etc.).
If you use a powered subwoofer that performs bass management, just connect your audio interface outputs to the subwoofer inputs, and your L and R satellites to the proper subwoofer outputs. This way the system will still be seen as a standard dual-channel system (with an increased low-frequency extension).

3.2.5 ­ How to connect the measurement microphone
Please connect your measurement microphone to a high-quality microphone preamplifier and enable the +48V phantom power supply.
Please check that your system meets either of these two requirements (either one is okay): 1. The preamplifier is built into the audio interface. In this case, the microphone will be directly connected to the
XLR input on the audio interface without using any attenuator pad and with +48V phantom power turned on. 2. The audio interface has no mic preamplifier. In this case, you will need to connect the microphone to an
external preamplifier or a mixer and then connect the preamplifier output to the audio interface line input.
To get the necessary precision, the preamplifier should be as clean and flat as possible. For this reason, you should avoid using tube preamplifiers for measuring. Also, electronically balanced (transformerless) preamplifiers are preferred over transformer-based designs which tend to color the sound too much for this need.
To start, set the gain control on your preamplifier to its middle position. Probably you will have to adjust this later on when setting levels.
IMPORTANT: TURN DIRECT MONITORING OFF.
Any direct monitoring of the audio interface mixer should be turned OFF. To confirm this, simply check that no microphone signal is going out to the speakers.

Using the ARC 4 Analysis

ARC 4
4.3 ­ Microphone selection
Select the measurement microphone you have by clicking 1 of the 4 tabs present on the Microphone Selection page of ARC 4 Analysis.

The ARC System 4 Measurement Microphone is available in 3 different versions:

1. early ARC 1 metal body microphones without the orange ring 2. early ARC 1 and ARC 2 metal body microphones with the orange ring 3. new ARC 3 and ARC 4 MEMS mic with black plastic body
   It is important to understand that none of the microphones are inherently better or worse. It is simply that due to a small difference in frequency response, the software must be told which microphone you are using to ensure the most accurate measurement possible.
   The system bases its accuracy performance on the precision of the analysis process, so it is strongly recommended to use a dedicated ARC microphone. However, in ARC 4, you can also perform the room analysis using a standard Measurement Microphone (sometimes also called “RTA Mic”) you might already have at your disposal.
   Measurement microphones are also called “RTA” microphones because they typically come with real-time audio spectrum analyzers. They are omnidirectional, with a flat frequency response, and are only used for taking audio measurements.

22

Using the ARC 4 Analysis

ARC 4
PLEASE NOTE: microphones designed for recording, even the omnidirectional ones, are normally not suitable for taking audio measurements, and if used with ARC, they will provide unreliable results.
To use your available Measurement Mic, select the fourth Mic selection tab, “Generic Measurement Mic.” You can now proceed to Room Analysis or, for better precision in the results, you can load a calibration file for your mic.
Calibration files (also called ECF by some manufacturers) are .txt files that describe the frequency response of your microphone and they are normally available from the Mic manufacturer.
To load your microphone calibration file, click on the “+” icon beside the Load Microphone Calibration label and proceed with the room analysis process. Now from the system dialog, browse and load the calibration file (or ECF).

Once you have selected which microphone type you have, click NEXT to proceed with the ARC 4 Analysis process. If you have not selected a microphone type, you will not be able to click NEXT to continue.
IMPORTANT: If the wrong microphone type is selected, the resulting ARC 4 correction will be inaccurate. Please take the time to make sure that you have selected the correct microphone to ensure an accurate measurement!

ARC 4 4.6 ­ Position the microphone
Now place and align your microphone horizontally and vertically, aligned with your ears. PLEASE NOTE: As indicated in the walk-through images, for all ARC 4 Analysis captures, the MEMS Measurement Microphone and all the generic measurement microphones must be positioned HORIZONTALLY, which is different than the ARC condenser microphones which require vertical positioning. Example of correct ARC MEMS mic positioning (this position is also correct for all generic RTA microphones):
Example of correct ARC Condenser mic positioning:

Make sure to clip the microphone on a standard mic stand.

Try to use a mic stand with a boom arm that is extended as far away from the stand as possible. This helps avoid reflections from the stand that will interfere with the analysis at high frequencies.

Do not stand or sit near the microphone while the analysis is running.

As indicated in the figure, the microphone has to be set at the same height where your ears are when you are listening to the speakers.

31

Using the ARC 4 Analysis

4.7 ­ Playback level/mic preamp level
Once the microphone is correctly positioned at the main position, you can start checking levels:
1. Make sure you are in a quiet environment, and try to avoid noise.
2. Lower your monitoring to the minimum level and click PLAY TEST.
PLEASE NOTE: The studio listening volume can be controlled on your audio interface with the main output level control or with your monitoring management system. If you are using a mixer, you can use your “control room” level. Click PLAY TEST. This will generate a test sound (chirp), and it will be sent to the outputs specified in the Audio Setup.
3. Gradually raise your monitoring level to hear the test at the same volume you usually have when mixing.
You should start hearing the test tone playing back continuously. Stop increasing the listening volume at the point where the test tone is at a medium intensity, more or less at the level that you generally work in your studio. CAUTION! DO NOT INCREASE THE LISTENING LEVEL TOO FAST. This could create damage to your speakers and your hearing if the monitoring system is very powerful.
4. Adjust the mic preamp level so that the input level falls into the “Correct” range.
Check the Input Level Meter indicator in the ARC 4 Analysis application. This meter shows the level of the signal captured by the measurement microphone.

33

Using the ARC 4 Analysis

ARC 4
While the test tone is playing, slowly adjust the MIC GAIN control on your audio interface (or on your microphone preamplifier) to have the Input Level Meter indicator display within the “OK” range.
PLEASE NOTE: In case you have increased the MIC GAIN control on your interface to maximum and still see a very low signal or no signal at all on the peak meter, check that all cabling and connections are okay and that +48 V Phantom Power is turned on.
Once you set the correct level, a green badge indicating “Done” will appear.

DO NOT CHANGE any of the audio settings (studio listening level, MIC GAIN control, etc.). Then click NEXT.

4.8 ­ Room Analysis
ARC 4 introduces the capability to assess the acoustics of the listening environments using two distinct settings: Advanced Mode and Quick Mode.
Advanced Mode: taking an array of points at three different heights, the system weights the captures in 3D so that the most relevant room issues are addressed without correcting positions that don’t affect your monitoring. The result is an incredibly accurate, natural sound that doesn’t sound processed or artificial.
The ARC 4 Room Analysis in Advanced Mode requires 7 capture points taken at 3 different height layers, for a total of 21 points.
Quick Mode: this option requires only one layer of 7 capture points at the ear level and it is ideal for on-the-go or ad-hoc setups, making it possible to measure the room in less than a minute.

IMAGE 4.8.1.1.1
IMPORTANT NOTE: The suggested analysis positions are not mandatory. You should follow them as they will always provide good, balanced, guaranteed results. However, if you like experimenting, you can also try different patterns, always bearing in mind to keep them symmetrical with the initial central point.
For example, you can take your points narrower and generally closer to your central sweet spot if you always work very close to the central sitting position, or vice-versa you can make them larger and analyze a wider area if you typically move more across the desk. As a general rule, always bear in mind that the closer the analyzed area is, the more precise and linear the monitoring system will perform in that specific spot. And vice-versa, the wider the analysis is, the more broad and “averaged” the response will be in that larger area. Of course, this will make a single spot in that area slightly less precise and linear.
Follow these simple steps to properly analyze the room.

Preparing to analyze:
DO NOT CHANGE ANY OF THE LEVELS THAT HAVE BEEN SET AT PREVIOUS POINTS IN THE WALKTHROUGH.
Quiet the room as much as possible (e.g., if you are using a fan and/or air conditioning, turn it off while analyzing your room). Be sure that the room doors or windows are set the same as during your usual listening. For example, don’t close the main door when capturing if this door is never closed while you are working or viceversa. If you usually work with a few people at each session, try to measure the room in the same conditions.
Taking the captures:
Place the measurement microphone in the main position.
Click CAPTURE POINT. Do not make any noise during the analysis process. A chirp will be played 4 times on the left speaker and 4 times on the right speaker for each capture. Do not walk, talk, or move while the chirps are playing or during pauses between the chirps. Do not touch the microphone until the ARC 4 Analysis display says “Done” and the white circle has moved to the next capture number.

5 ­ Using the ARC 4 Plug-in
5.1 ­ ARC 4 plug-in interface
The ARC 4 plug-in is a multiplatform audio processor that applies the correction curve measured with the ARC 4 Analysis application to the incoming audio stereo signal in real-time. It is comprised of two operation windows, each dedicated to specific tasks: Play and Edit.
5.1.1 ­ Play Window
This window is where you can view how ARC 4 is performing the correction on your monitoring:

The ARC 4 plug-in applies one of the measurement sets you have saved from the ARC 4 Analysis application on your stereo master bus to match several different target curves. You can switch from one measurement set to another allowing you to compare your saved options to meet your various sonic needs.
It will also show graphical frequency responses for the left and right channels both before and after the correction. The left and right channels are individually selectable by clicking on the colored tiles above the graph.

The ARC 4 plug-in alters the stereo master bus level. For this reason, a precision peak meter with several metering options is included to show both input or output levels (pre/post) so that the actual project master level can still be kept under control. Derived directly from the internationally acclaimed T-RackS 5 metering, this highquality metering section offers PEAK, RMS, Loudness (LUFS), and Dynamic Range (DR) indications for both the PRE and POST processing signals.

ARC 4

5.1.3 ­ Target Curve menu
ARC 4 comes with 9 factory-tailored target curves suitable for most situations. The “Default” one is for optimal balanced results, plus “Flat” and other specific ones for different specific needs or setups.
You will notice that the Default target curve, which is the one that is automatically generated by the system, is not flat, but has a small boost in the low frequencies and a very small attenuation in the high frequencies. This defines the system target curve that will be optimal for most acoustic spaces and with most studio monitors, without appearing too bass shy or too harsh. This is because most closed acoustic spaces naturally tend to boost the low frequencies by a certain amount, and for our hearing system some of this natural boost has to be preserved in closed spaces after the correction, to avoid the space sounding too thin or dry. The important aspect of this is that after the ARC optimization the low frequency slight boost will be even and uniform, and musically coherent, and not “spikey” or disorienting as when the room is not corrected.

Click this menu to select one of these Target Curves:

· Default · Flat · Standard Control Room

· Lively Room · Lively Room 2 · Control Room Contour

· Dolby Atmos Target · Warm Tilt · Bright Tilt

49

Using the ARC 4 Plug-in

ARC 4
The other Target curves are defined as follows:
FLAT: This one produces a totally flat free field frequency response from the system, at the listening position. As said this might result to our ears a little dry or bass-shy in closed spaces, as for example a typical control room, that’s why this is not the default one. In any case, it can easily be selected for those users who prefer having an instrumental flat response.
DEFAULT: This one produces a slight boost in the low end and a very small attenuation in the high frequencies. This is useful to “rebalance” the correction for most closed listening spaces like control rooms. This is because closed spaces tend to boost the low frequencies and our hearing system is used to that gentle tilt..
STANDARD CONTROL ROOM: This one takes into account the typical slight bass and mid-bass boost you normally find on nearfield monitors when placed on the top of a console, or immediately behind it on stands, and recreates it after the correction, to make this setup sound more familiar even after the calibration, still removing unwanted and disorienting low-frequency resonances and spikes/dips.
LIVELY ROOM 1 and 2: These ones are mostly intended for reverberant rooms, like home theaters and living rooms, or studio live rooms where the natural reverberation of the room has a certain damping on the high frequency, which should be retained after the calibration to avoid the system to sound too harsh.
CONTROL ROOM CONTOUR: This is similar to STANDARD CONTROL ROOM, but it also implements a slight attenuation of the extreme high end. It’s especially suitable in control rooms that have a certain liveness in the acoustics.
DOLBY ATMOS TARGET: This replicates the suggested target curve for Dolby Atmos for music monitoring. WARM TILT: This is a generic warm response, suitable for reverberant rooms with lots of reflective surfaces like big windows or reflective material in general, where the correction could push the system to sound a bit too harsh.
BRIGHT TILT: This is a generic bright response, useful in very damped rooms and when the speakers are very close to the listening area, where the correction could result in an slightly “dark” sound.
8 user-definable curves are also available and reflect the settings of their corresponding selections in the EDIT page of the plug-in.

5.1.4 ­ Virtual Monitoring feature
For a fast and convenient check of how your mix translates in various “real world” conditions, we’ve provided a brand-new set of more than 20 alternative speakers and device responses which are listed in the Virtual Monitoring menu. These additional curves are real frequency responses of professional and consumer devices (renowned and popular studio monitors, typical hi-fi speakers, TV sets and smartphones) which will let you audition how your mix translates with many different listening setups.
Since the sonic signature of those alternative systems is played over a perfectly calibrated system with ARC 4, the result will be like mixing in a transparent and balanced room with different speakers.
5.1.5 ­ Frequency Response graphs
The ARC 4 plug-in shows two frequency response graphs, one for the left channel and one for the right channel. Each frequency response graph is individually selectable by clicking on the colored tiles above the graph and showing the three color-coded curves.

GREEN CURVE (Before): This represents the original measured speakers/room frequency response.
ORANGE CURVE (After): This represents the corrected speakers/room frequency response.
WHITE CURVE (Target): This represents the selected Target Curve. The target curve is by default slightly bassboosted as explained above in this manual. If other target curves are selected, their response will be shown here.
RTA: ARC 4 plug-in provides a real-time analyzer which can be activated or deactivated by pressing the RTA button on the top right corner of the graph. The real-time spectrum analyzer shows how your music was interacting with your room before correction.
5.1.6 ­ Speaker Icons
The ARC 4 pplug-in shows the speaker icon that was chosen when the analysis was saved in the ARC 4 Analysis application. This is useful to identify and recall the measurement sets already taken and their association with a real speaker model. Note that the speaker icon selection is just a mnemonic aid and does not interact with the sound of the ARC System 4 in any way.

5.1.7 ­ Meter Options
These precision Meters shows the INPUT level (unprocessed) or OUTPUT (processed by the ARC 4 correction).
On the Meter, click PRE to check the unprocessed input signal level. This mode is very useful to keep the actual stereo master level of your project under control. Remember that ARC 4 is changing the stereo master peak level, so the DAW output meters will not show the actual real level anymore. Use the ARC 4 Meter in PRE mode to monitor the actual project level.

On the Meter, click POST to check the ARC 4 processed signal level.
Also, Derived directly from the world-acclaimed T-RackS 5 metering, this high- quality metering section offers PEAK, RMS, Loudness (LUFS), and Dynamic Range (DR) indications for both the PRE and POST processing signals. Click on the metering options button as shown in the figure.

ARC 4
5.1.8 ­ Correction ON switch and TRIM knob
To enable the correction, click the CORRECTION ON switch. When it is lit, the correction is active. TRIM knob: The TRIM knob affects both the corrected and uncorrected sound so you can use it to compare the “before” and “after” monitoring at an equal loudness. The system allows the Trim control to detect the maximum boost level in the correction filter. So, every time you edit parameters that affect or alter the filter correction, or every time you select a new measurement set, the Trim will provide a dynamic red band to indicate the level above which you should not exceed. Each time the filter is re-calculated, the dynamic red band will update accordingly.
The TRIM knob has a range from -30 to 0 dB and the default position when opening the ARC 4 plug-in is the point of intersection between the grey band and red band, which is the middle position just before you go risk clipping.

5.2 ­ Edit Window
The ARC System 4 correction plug-in allows for more flexibility and superior sonic results when compared to previous versions.
You can use the controls in the Edit window to adjust the correction to your taste by using Lo/Hi Range controls, variable resolution (or Smoothing), Linear or Natural phase options, or dragging the 6 breakpoints in the graphic for gentle tone-shaping while still getting all the benefits of the ARC 4 correction.

Using the 6 breakpoints in the graphic will not alter the correction ARC 4 has applied to your monitoring setup (as you might think at first glance). It will instead allow for more tonal options to suit your listening preferences.

ARC 4
5.2.4 ­ Combined L/R correction
In most cases ARC 4 considerably improves the stereo image precision, and so the center ghost image which will become dramatically more precise with ARC 4 correction ON.
However, for strongly asymmetrical rooms, where the low frequency response on a channel is very different from the one of the other channel, you might notice a certain amount of phase incoherency on the low frequencies between the two channels, when the correction is ON.
This can be solved by using the “Combined L/R Correction” function.
When this option is selected, ARC 4 will average the correction required by the L/R channels and then apply it the same way to the two channels. While this from a theoretical point of view is a compromised solution, for certain strongly asymmetrical acoustic setups can be actually beneficial.

58

Using the ARC 4 Plug-in

ARC 4
5.2.5 ­ Low-range and Hi-range correction
The correction is by default applied to the whole spectrum, from 20 to 20 kHz.
However, it is possible to limit the range where the system applies the correction on both sides (Low and Highs) of the spectrum. This can be for example useful to retain the voicing of the monitors when this is preferred, still being able to correct the issues generated by the room at low frequencies, or when it is preferrable to have the system to avoid overboosting the low frequencies too much, making for example, the correction to start at a higher frequency than 20 Hz, for example 50 Hz.
Move the Low and Hi Range knobs and the two corresponding lines on the graph will move accordingly.

59

Using the ARC 4 Plug-in

ARC 4
5.2.6 ­ Correction Type (or Variable Resolution)
The default setting of ARC 4 will work fine in most cases, however not all rooms react the same to the correction process. With this control, the system offers the possibility to adjust the resolution of the correction filters smoothing, allowing the intervention to be more narrow-band and selective or smoother and more broadband.
This has a subtle effect, but sometimes details make a big difference in monitoring, and this allows the user to manually set the final detail of the automated process to perfectly match the results to personal preference.
From the drop-down menu, select the Default, Sharp, or Broad option, and choose your preferred one by listening to the results of the correction.

60

Using the ARC 4 Plug-in

ARC 4
5.2.7 ­ Natural/Linear Phase Options
Left and Right channel phase coherency is crucial for a quality monitoring system, but sometimes speakers are installed in a less-than-ideal symmetrical arrangement in the room. This can cause severe phase misalignment, especially at low frequencies, between the left and right channels, making it impossible to mix properly (aside from being a less-than-pleasant condition for listening).
NATURAL mode improves the phase coherency between the L and R channels, recovering a better center ghost image that might be compromised by the effects the room has on the sound, especially at low frequencies. This is the default and preferred mode for most applications.
LINEAR mode is a special correction mode where the original inter-channel phase response of the speakers’ system is maintained unaltered. In certain cases, this mode can be preferable for even better transparency. However, this mode adds a little bit of latency, around 50 milliseconds.

ARC 4
5.3 ­ Opening the ARC 4 Plug-in in your DAW
The ARC 4 plug-in is a “stereo-to-stereo” processor that should be inserted on the stereo master bus of your audio sequencer or digital audio workstation.
The ARC 4 plug-in should remain inserted and active on the stereo master bus during the entire recording, mixing, and mastering processes. But then just before printing the final mix to a file or an external recording device, it must be turned OFF.
This is because the ARC 4 plug-in is used to correct the monitoring/room system response. It is NOT intended to process the actual mixdown of your project.
A few DAWs support a dedicated monitoring bus where you can insert plug-ins. In this case, the ARC 4 plugin should be inserted on the monitoring bus instead of the stereo master bus so that the ARC 4 plug-in will not affect the actual mixdown of your project even if you don’t turn it OFF before printing the mix.
Each DAW has its criteria for how to use aux tracks, monitoring buses, master tracks/faders, etc. Therefore, these suggestions for how to start ARC 4 in several host applications are just a starting point, a guideline. For example, if your session already has a master track, you do not need to create another one. Just insert ARC 4 as the last plug-in. We recommend that you read your DAW manual chapters specifically related to outputs, monitoring bus, master tracks, routing configurations, etc.
Considering that DAWs are constantly updated, refer to their User Manuals to learn how to insert ARC 4 as a plug-in.
The ARC 4 plug-in is compatible with VST, VST2, AAX, and Audio Units plug-in formats on both (where applicable) Windows and macOS platforms. Please refer to the Installation and Authorization Manual for further details.

63

Using the ARC 4 Plug-in

5.4 ­ Using the ARC 4 Plug-in
Open your DAW.
Create a new session or open an existing one.
Open the DAW audio mixer and locate the stereo master bus. If you are using Pro Tools and your session does not have a stereo master bus yet, create one.
Load the ARC 4 plug-in as the LAST processor on the stereo master bus.
From the measurement menu, select one of your saved measurement sets.
Click the Correction ON Switch. When it is lit, the correction is ON.
If you are using mastering processors (like T-RackS), be sure to insert the ARC 4 plug-in AFTER all the other processors. The ARC 4 plug-in must always be the LAST one in the processing chain.
If your master level is really hot, (very close to 0dB), be sure to not overload the stereo master bus with the ARC 4 processing.
If clipping occurs when checking the ARC 4 Peak Meter in POST mode, use the TRIM knob to lower the level. Keep the ARC 4 plug-in inserted on the stereo master bus throughout the entire recording, mixing, and mastering process.
IMPORTANT: Switch the ARC 4 plug-in OFF before bouncing the project to a disk file. Your final mix should NOT include the ARC 4 processing because it is designed for MONITORING use only.

5.5 ­ Suggestions for the best ARC System 4 usage
You are probably used to how your studio acoustics sounds and already know how to use ARC.
Just use this information as a reminder, and follow these suggestions to enrich your listening experience while using the ARC System:
Use audio material you know are very familiar with to evaluate the new way your studio sounds.
Always give yourself time to get used to the new sound. Do not judge the corrected system by only listening for a minute or two. Always give yourself enough listening time to understand how different the room sounds.
Do not change between various measurement sets or turn the correction ON / OFF too often. Your hearing system needs to get used to it. It is like when your eyes need some time to adapt to a very different lighting condition such as going out of a dark room into bright sunlight.
After you select the best measurement set, you will start using the ARC System 4 without even thinking it is there. It is a “set and forget” tool that will help you mix faster, and better, and achieve greater consistency with your artistic projects.

The ARC 4 Standalone is the application that is used to set and control the ARC Studio hardware device. It shares the same operativity as the ARC 4 plug- in described in the previous chapter with only a couple of minor changes described in the following paragraphs.

6.1.5 ­ TRIM Knob
The TRIM knob in ARC4 Standalone serves a different function compared to ARC4 plug-in and therefore features a different value range of ± 15 dB.
On the plug-in, this knob is used to attenuate the signal to avoid clipping the master bus because of the boosts the ARC 4 correction can provide, however, the ARC Studio hardware has plenty of headroom so no attenuation is necessary to accommodate such boosts. The TRIM control can, this way, be used to align various monitoring systems at the same loudness.

7 ­ Frequently Asked Questions
7.1 ­ Room Analysis
Can I use previous room measurements I made with previous versions with ARC 4?
No. Room measurements taken with ARC 1, ARC 2, or ARC 3 are not compatible with ARC 4. The advanced algorithm in ARC 4 needs more info from the room acoustics that were not captured with the ARC 1 or 2 or 3 measurement process.

What is the best microphone to use with ARC 4?
To get the best possible results in terms of accuracy you should use the ARC 4 MEMS Microphone. With this mic, ARC 4 ensures a precision within +/- 0.5dB, which is a quite remarkable level of accuracy! It’s the best investment you can make for your studio, it’s a reasonably priced microphone, and it offers great stability with time and temperature, so it will always deliver the same reliable results over the years.

Are the older ARC microphones (silver metal models) still good for ARC 4?
With normal “recording” microphones the accuracy of the frequency response down to the dB or fraction of dB is not that crucial, but for measurement microphones, it’s a fundamental aspect.
There were two models of the original ARC condenser microphone, one with an orange ring at its base, and one without; the first model is from 2007 and it’s the one without the orange ring.
Condenser microphones tend to vary their response with environmental conditions and with age.
In 2009 that mic was replaced with the second model (with the orange ring) to improve the stability with time and temperature.
So, if you own one of the original ring-less microphones that were sold between 2007 and 2009, while you can use and hear the results, there are chances that its reliability is not as great as today (15+ years later), making the precision of the ARC 4 correction less accurate.
The second model was more stable, but even that one was surpassed in terms of precision and stability with environment and age by the ARC 4 MEMS microphone.
So, if you’re after a great level of accuracy from your monitoring system, make sure to use the ARC 4 MEMS microphone for the room analysis phase.

I have seen that ARC 4 supports 3rd parties “measurement microphones”. What exactly is a measurement mic and what is a microphone calibration file?
Measurement microphones (also called RTA mics, or room analysis mics) are particular microphones that are normally not suitable for recording. They are true omnidirectional microphones with an exceptionally flat frequency response used for taking acoustical measurements in spaces. They normally have a very thin and long body shape to minimize the impact of the mic body on the linearity of the frequency response.

72

Frequently Asked Questions

ARC 4
Measurement microphones are very linear ones, however, they’re not perfectly linear. For this reason, most manufacturers provide a “microphone calibration file”, sometimes also called “ECF”, usually in a text format (.txt file). This file describes the response of the mic so that it can be loaded into the software that will compensate for it, making the microphone behave as if it were perfectly linear.
I have a recording condenser microphone that can be set to “omni” and has a remarkably flat frequency response. Can I use it with ARC 4?
No. Normally these microphones are not neutral enough and their polar pattern is not “omni” enough to provide good results in measuring room acoustics. This said you can always give it a try, if the ARC 4 correction sounds balanced and neutral the mic was fine for the application, however, we strongly suggest avoiding this.
Is it mandatory to load calibration files for the generic measurement microphone option?
No, you can use any measurement microphone even without loading the calibration file. However, the accuracy in that case will strongly depend on the linearity and overall quality of the mic. Instead, when loading a calibration file, any issue on the microphone frequency response will be addressed by the calibration, providing more reliable results.
Is the accuracy of the mic positioning during measurement affecting the quality of the results?
Don’t tape your floor, that’s not needed! The positioning indications given on the ARC 4 Analysis application during the process are explicative of where the mic should be positioned. No absolute indications are provided because they are not needed, the mic should be placed approximatively on those spots, really hand-placing the mic stand approximatively at those spots will do. The quality of the results will only be affected if you place the mic a lot differently than what’s illustrated onscreen at the various steps.
Should I use a mic stand for the measurement process?
Yes! The mic must be as steady as possible and stable during each single measurement spot recording. If the mic moves even a little bit during the recording of each point, the results will be compromised. Also, there should be nothing moving in proximity to the mic, to the speakers, or between the two while these points are recorded.

73

Frequently Asked Questions

ARC 4
Can I stay in the room while the Analysis process is recording each point?
Yes, but try to keep yourself outside the listening spot and not too close to the microphone or the speakers to avoid sound reflections that can compromise the reading.
Should I keep doors and windows closed while analyzing the room?
Doors and windows have a big impact on the frequency response of the room, so they should be in the same state they are when you normally work. If your studio door is normally open then measure up the studio with the open door, and vice versa.
What is the best playback level I should set my listening level to when measuring the room?
Set the listening level so that, when the ARC 4 Analysis application plays the test signal, you get a loudness in the room similar to the one you have when working normally.
There is a considerable level of background noise in my studio, can I measure the room reliably?
In this case, you will need to raise the listening level during the measurement process to get to a decent signalto-noise ratio during the recording of the points.
Can I experiment with different mic positioning than those indicated by the Analysis application?
We suggest starting with the pattern of points that are indicated by the Analysis application and sticking with them. However, once you are familiar with the results, you can for sure experiment with different positioning. The main concept to keep in mind is that the system optimizes the monitoring system in the area where the measurement points are taken. For example, you can experiment with taking the 7 points per layer in a narrower or wider spot, and so on.
I have a 2+1 system that includes a subwoofer, how should I measure the room?
If the subwoofer is handling the crossover and feeding the main speakers, or if you are using an external crossover the system will be seen as a normal 2-channel setup, so you can use ARC 4 without any issue. ARC 4 will also adjust the level of the LF range matching it perfectly with the main speakers.

74

Frequently Asked Questions

ARC 4
Are the quality of the audio interface and mic preamp used for the room analysis important for the result’s accuracy?
Generally speaking, yes. Anything wrong that might happen during the room analysis process will translate into the response of the final system. The interface used for analysis should at least have a flat frequency response (+/-0.5 dB) up to 20 kHz and down to 20 Hz and be able to operate at 48 kHz. Clean preamplifiers are preferred for this process. If possible, try avoiding using tube preamps for the measurement mic, vintage ones, or ones that add too much harmonics/coloration to the sound as this will affect the accuracy of the results.

75

Frequently Asked Questions

ARC 4
7.2 ­ Processing Plug-in
How should I use the correction plug-in in my DAW?
The correction plug-in should be inserted on the stereo master bus of your project or, when this is available, on the monitoring bus of the DAW. Unless your DAW allows for inserting the plug-in on a monitoring bus, remember to ALWAYS switch off the ARC 4 plug-in before exporting/bouncing/rendering the program from the DAW. The ARC 4 plug-in should always be the last in the chain on your master bus. If you use master-bus processing like EQ, compression, limiting, and so on, make sure the ARC 4 plug-in always comes after those.
How much latency is the ARC 4 plug-in adding to the system?
The ARC 4 correction plug-in can work in two-phase modes: NATURAL and LINEAR. NATURAL has a latency of 64 samples, LINEAR has a higher latency of 2100 samples.

While analyzing the room, I got error messages from the ARC 4 Analysis application related to the low signal and high background noise. As a result, I can’t complete the analysis process. What should I do?
Quiet down the room as much as possible or increase the test tone playback level during the analysis process. Also, check the microphone level again and repeat the capture.
While analyzing the room, I got “phase” errors from the ARC 4 Analysis application.
Please check your speaker’s wiring. If the speakers are passive, check the polarity of the leads going from the amps to the speakers. If the speakers are active, check the XLR or TRS cable connections and polarities.
When I open the measurements set on my ARC 4 plug-in and turn the Correction ON, the resulting sound and the displayed response are strange and incorrect, making the monitors sound worse than when the ARC 4 plug-in is not enabled. Do you have any suggestions?
Be sure that your audio interface is set to 48 kHz when running the ARC 4 Analysis application. Also, check your audio interface buffer size settings. It should be set from the minimum supported by the hardware (best option) to 2048 samples for a proper analysis.
I am trying to set the microphone levels on the ARC 4 Analysis application. However, even if the test signal is being played back from the speakers, I cannot see any level. What should I do?
Please check which audio input has been selected on the ARC 4 Analysis Application Audio Setup page, if the +48V phantom power is ON, and if the XLR cable is properly connected, (eventually, check if the cable is in good condition).
When I open the measurements set on my ARC 4 plug-in and turn the Correction ON, the resulting sound is not optimal, and I don’t feel it is correct for my monitors and my room.
