REGISTRATION AND FIRMWARE UPDATE

Registration
By registering your iD4, you will be notified when new versions of firmware are made available via email. These firmware updates allow us to improve iD4’s performance and even potentially features. To register your iD4, please go to: audient.com/register-a-product
Firmware Update
Once firmware updates are made available,  they need to be applied to iD4. This is done through the iD app.
macOS
iD4 is class-compliant, which means that no drivers are needed for operation. However to update the firmware, download the iD app from our website at: audient.com/id4-downloads
Drag the app into your applications folder and open it. If there is a firmware update available, you will be prompted to install it.
You do not need to have the iD app running on Mac for the regular operation of iD4.

Windows
For regular Windows operation, the iD app must be running, therefore when a firmware update is available you will be notified. To check manually, right- click on the iD icon in the system tray and select Check for Updates.

iOS
Firmware update is not possible on the iOS platform, so you will need to plug iD4 into a Mac or Windows computer and update the firmware from there.
Offline Computers
If your audio computer is not connected to the internet, you can download the firmware update file from the iD4 page, transfer it onto your offline computer, and then select From File… in the firmware update screen, and then choose the firmware file.
audient.com/id4-downloads

NOTE
Ensure that you restart iD4 after installing a firmware update by disconnecting and reconnecting the USB cable. This ensures all updates have been properly applied.

HARDWARE FEATURES

HARDWARE

Microphone Preamplifier & Line Input
iD4 features a single classic Audient microphone preamplifier. This preamp is based on designs from Audient’s classic consoles and is the same that are used across our entire product range.
The design features discrete, Class-A circuitry providing exceedingly low distortion and noise performance. From a sonic point of view, iD4 is fast, open, and detailed.
Neutrik™ XLR/TRS Jack combi-connectors provide microphone and line inputs in one compact connector.
When using a condenser microphone you will need to use phantom power otherwise you will not get any signal. To activate phantom power, press the +48V switch next to the input connector. The +48V phantom power indicator LED will illuminate red when phantom power is activated.

The microphone preamplifiers feature:

• 58 dB of clean gain
•  48v (±4V) phantom power rated at 10mA
•  > 2.8kΩ input impedance which provides a punchy tone from any microphone type

D.I Input
iD4 uses a discrete Class-A JFET instrument (D.I) input on channel 2, which is easily accessible at the front of the unit.
The D.I input is perfect for plugging in electric or electro-acoustic guitars, as well as basses and even synthesizers. The JFET circuitry adds a tiny bit of color and distortion to the signal, giving your instruments a bit of added warmth.

Loudspeaker Outputs

iD4 has stereo speaker outputs on the back panel in the form of balanced TRS jack connectors. The outputs are fed from high-quality Digital to Analogue Convertors (DACs), sending clean, detailed audio to your speakers.

Headphone Outputs

iD4 features a high current headphone amplifier. This can be accessed using both the 3.5mm and 6.35mm sockets found on the front of the unit. The same audio signal comes out of both connectors simultaneously, so it does not matter which you plug your headphones into. You can also plug in two pairs at the same time.
Headphones can be used instead of, or alongside speakers to get an idea of how your mix sounds on headphones or to provide an artist headphone mix.

Monitor Control

Volume Encoder
The Volume encoder allows you to change the volume of the audio for both the speaker and headphone outputs. Pressing the encoder will dim the audio, dropping the level by 15 dB, useful if you want to quickly turn down the level to your speakers/headphones without losing your listening level. As you adjust the volume level, the main meters will change to show the level you are setting it to, before changing back to show the output level.

Monitor Mix
The Monitor Mix knob lets you monitor the mic and D.I inputs, while still being able to hear the audio coming from your computer (DAW) at very low latency to avoid distracting delays.

NOTE
Listening to speakers while monitoring your input from a microphone in the same room can cause feedback, which not only is unpleasant but could also potentially damage your speakers. Ensure that either the speakers are muted, or that the monitor mix is set all the way to DAW when not using the microphone.

Monitor Pan

iD4’s Monitor Pan feature enables you to pan both the mic pre and DI input from left to right, making it easy to create a balanced headphone mix that suits you. Press and hold the Mute and iD buttons whilst turning the Volume Encoder to pan the inputs.
Twisting clockwise pans channel 1 left and channel 2 right while twisting anti-clockwise pans channel 1 right and channel 2 left.
Pressing the encoder whilst holding the Mute and iD button will reset the pan.
As you adjust the monitor pan, the meters show the pan positions of the mic and D.I, where
the top meter shows the Mic/Line Input, and the bottom meter shows the D.I Input.|
---|---

MUTE Speakers Button
The MUTE Speakers button is a quick way of muting the speaker outputs whilst allowing audio to pass to the headphone outputs, allowing you to hear what you are playing while you are recording.
If you are using a microphone in the same room as your speakers, then it is important to mute your speakers while recording to prevent unwanted audio from being picked up by the mic or getting feedback.

iD Button
Pressing the iD button will activate ScrollControl, which allows the encoder to be used as a scroll wheel for your computer. This works well for controlling plugin parameters and adding automation in a more hands-on way.

To use ScrollControl, hover your mouse over whatever you want to control and rotate the encoder. If you find it is too sensitive or not sensitive enough, you can try adjusting your computer scrolling speed is found in your computer settings.
ScrollControl may act slightly differently on certain plugins or DAWs depending on how they have been programmed to work with mouse wheel scrolling. You may find some controls/software do not support ScrollControl.

Metering
As mentioned in previous sections, the meters change to display positions and values for different settings on iD4, however, when not adjusting any settings, it will display the peak output level.

Status LED

The Status LED indicates connection via USB to your device. A solidly lit light means that there is stable communication between iD4 and the device.

Kensington Lock
For those who work in educational establishments or in situations where your equipment is public-facing and subject to possible theft opportunities, we have provided a Kensington lock hole to enable you to protect your iD4.
A desk mounting plate is also available, please contact Audient for more information.

GENERAL OPERATION

This next section will give some insight on how to get the most out of iD4, and some of the different settings and options you have available to you when using it.
Sample Rate
When starting a new project, it is important to consider the sample rate you are using.
The sample rate dictates how many times a second the level of the incoming audio is measured (sampled), which allows continuous analog audio to be represented digitally as a series of 0s and 1s.
44.1kHz is the standard sample rate for all CDs and most downloadable music, while 48kHz is the standard for people working with film. Higher sample rates can have their benefits but it is worth noting that as you increase the sample rate, you increase the file size of the audio and CPU resources required.
Buffer Size and Latency
Buffer size is a very important setting that will ensure that your projects are running smoothly and efficiently. A wrongly selected buffer size can result in hearing pops, clicks, and stuttering audio. Buffer size dictates how many “samples” of audio are stored before being sent to the output.
A buffer adds a delay to the signal (known as latency), however, it is essential for giving the computer some time to do other processing.
If you are monitoring iD4’s inputs directly using the Monitor Mix knob, you can keep the buffer size relatively high to reduce the strain on your computer. If you are wanting
to monitor through your DAW with effects, for example being able to hear your electric guitar with an amp simulator on it, you will want the lowest buffer size your computer
can handle. The buffer size you can get down to before you get audio issues is hugely dependent on your computer power, as well as the processing requirements of your session. Some DAWs allow you to “Freeze” tracks which reduces the CPU load, allowing you to choose lower buffer sizes.
For mixing, you can set the buffer size much higher, to allow your computer to process the audio in time. Increasing the latency does not really matter in this situation because
you aren’t trying to do anything live. For larger sessions, you might find that you need a larger buffer size than normal.
You may need to adjust buffer sizes when working at different sample rates to account for the difference in CPU requirements of different sample rates.

macOS
The buffer size is selected from within your DAW, most likely in an audio settings or preferences menu.

iOS
The location of the buffer size setting (or having a setting at all) is dependent on the app that you are using. Generally, it will be found in the app’s preferences/settings menu, or alternatively by finding the app, in the iOS settings app.![AUDIENT iD4 USB 2 in 2 out High Performance Audio Interface

Windows
On Windows, buffer size needs to be selected in the iD app before the DAW. A Latency setting must be selected first, which refers to how often iD4 sends and receives its data.
After, the buffer size can be selected. For mixing, a latency for “Standard” with a buffer size of “256” will give you a good starting point. Then simply increase or decrease both
the Latency and Buffer Size settings as you require. If you wish to experiment, you may find that certain combinations of Latency and Buffer Size settings work well for you.

Windows Latency Modes:

LOGIC PRO SETUP

Operation with Logic Pro
With iD4 plugged into your Mac, launch Logic Pro and ensure that iD4 is selected as your Input and Output Device: Logic Pro > Preferences > AudioOnce iD4 is selected as your device, set the appropriate buffer size for your session.
If you are using the Monitor Mix knob to monitor your inputs, you can set the buffer size reasonably high to reduce the strain on your computer. If you are experiencing issues with playback stability or “overload” errors coming up, try increasing the buffer size.

If you are opening an existing session, iD4’s sample rate will automatically change to match the project. If you are starting a new session, be sure to select the appropriate sample rate found in: File > Project Settings > AudioIf you are monitoring your input signal on iD4, disable Logic’s software monitoring to avoid hearing duplicate signals as this can be very off-putting.
Logic Pro > Preferences > Audio > General > Software Monitoring

PRO TOOLS SETUP

Operation with Pro Tools
If using Windows, ensure that you have followed the installation instructions found on page 6.
With iD4 connected, launch Pro Tools and ensure that a new session is created at the desired sample rate. If you are using Windows, make sure that you have already set your Latency and Buffer Size settings in the iD System Tray before opening a project. Changing this mid-session will result in Pro Tools needing to restart.

Playback Engine
Go to Setup > Playback Engine… and ensure that iD4 is set as the active playback device.

Go to Setup > I/O… to label your inputs and outputs and ensure that iD4 is correctly reporting 2-inputs and 2-outputs to and from Pro Tools. If using the iD4 Monitor Mix knob to monitor your inputs, ensure that the input monitor button on the audio tracks is not selected, to avoid duplicate signals. For more Pro Tools information consult your Avid user manuals & documentation.

CUBASE/NUENDO SETUP

Operation with Cubase / Nuendo
If using Windows, ensure that you have followed the installation instructions found on page 6.
With iD4 plugged into your computer, launch Cubase or Nuendo and head straight for the Devices Menu:
Devices > Device Setup…
Select VST Audio System in the devices menu.

Ensure that Audient iD4 is selected as the audio device. You will be asked if this is OK, select ‘switch’.Select Audient iD4 in the devices menu, here you will see the main iD4 information.
Buffer sizes can be set in the Control Panel within the VST devices display.
Close the VST device setup panel and navigate to the VST connections panel:
Devices > VST Connections (F4) Here you can ensure that all buses have been created in Cubase / Nuendo and therefore all ports are addressable in your session. Add new buses and assign them to the necessary I/O if required.

If using the iD4 Monitor Mix knob to monitor your inputs, ensure that input monitoring is turned off on the track.

ABLETON LIVE SETUP

Operation with Ableton Live
If using Windows, ensure that you have followed the installation instructions found on page 6.
With iD4 plugged into your computer, launch Ableton Live and head straight to: Live > Preferences > Audio

In the Audio tab make sure that iD4 is assigned as the playback device. you can also select the appropriate sample rate for your project, as well as the buffer size.
If using Windows, ensure to set the Latency and Buffer Size in the iD System Tray before changing it in Ableton. If you are monitoring your inputs using the Monitor Mix knob, then you can keep the buffer size reasonably high to reduce the strain on your computer. In this case, you also need to make sure that input monitoring is turned off on the track in Ableton. For more information about setting up audio I/O refer to your Ableton Live user manuals & documentation.

TROUBLESHOOTING & FAQ

Troubleshooting

• “The unit will not power on”
  Double-check that the USB cable is plugged in firmly. If it still won’t power on, try using a different USB port on your computer and possibly a different USB cable. If you are using a USB hub, try plugging iD4 directly into the computer.

• “I get clicks and pops on DAW playback”
  This is most likely to do with setting the buffer size too low for your computer.
  This can be caused by running very large projects with a lot of plugins and virtual instruments. Experiment with higher buffer sizes (and Latency settings in Windows).
  Typically you want small buffer sizes for tracking or recording software synths to keep the latency low. However, when mixing it is fine to set a slightly higher buffer size as latency is not so much of a problem.
  It is also possible for driver conflicts to cause clicks and pops. For further details go to: support.audient.com

• “When I connect to my computer, I cannot play any audio out from iD4”

Firstly double check that the USB cable connecting iD4 to your computer is functional and attached at both ends. Then make sure that iD4 is set as the active playback device in your DAW and computer: System Preferences > Sound > Output Tab > Audient iD4 (macOS)
Control Panel > Hardware and Sound > Sound > Manage Audio Devices > Audient iD4 (Windows)
Finally, check that the Monitor Mix knob is set to DAW and not all the way to Input.

• “I keep getting loud feedback in my speakers”
  This is most likely caused by monitoring your microphone input while your speakers are on in the same room. Please make sure that you either move the monitor mix knob all the way to DAW if you aren’t wanting to monitor your input, or if you are, simply press the MUTE Speakers button and listen on headphones.

• “I hear an echo when recording”
  This is most likely due to input monitoring being enabled in the workstation while also using the zero-latency monitoring in iD4. For more information on this see page 13.
