Features Pt. 1

The Harrison 32C console is one of the most famous, highly regarded recording and mixing consoles of all time. It was used on Michael Jackson’s “Thriller”, Paul Simon’s “Graceland” and other recordings by Janet Jackson, AC/DC, Led Zeppelin, ELO, Genesis, Blondie and Supertramp to name just a few. The very same, extremely high-grade preamps that existed within the 32C consoles feature in the ‘32Ci Analog Mic Preamp with Audio Interface’, a co-branded collaboration between iCON Pro Audio and Harrison – a significant development in the world of audio interfaces.

The 32Ci comes packed with features, geared towards the high-end user.

With pre-amps of such distinction from the legendary Harrison 32C consoles, you would expect equally super high-end Digital to Audio and Audio to Digital convertors (DA/AD) – and that’s exactly what you get.

The 32Ci outperforms or matches similar, high end devices in its class with
129 dB Digital to Audio dynamic range and 120dB THD+N, (total harmonic distortion + noise).The 32Ci also delivers excellent audio to digital conversion, namely 125 dB dynamic range and -117 dB THD+N, . This provides the 32Ci with an expansive, natural sound that effortlessly challenges dedicated high-end converters.

Two ‘headphones out’ sockets makes it easy for collaborators when recording in a session. No need for headphone ‘splitters’ when say, a guitarist and a vocalist are working together or maybe an engineer and a vocalist – simply plug in and your headphone monitoring is covered. Each can even have their own separate headphone mix, (depending on your DAW software).

The 32Ci Analog Mic Preamp with Audio Interface also offers the user optical I/O with ADAT as well as two Neutrik ® Combo XLR Mic/Line In Connectors, which combine an XLR connection and a 1/4″ phone jack in one housing as well as two separate 1/4” Line Inputs. Combined with four 1/4” outputs, the 32Ci gives you plenty of scope to manage your I/O needs.

MIDI in/out ports allow you to connect MIDI devices directly via the 32Ci and the USB C Instant Live Streaming connector port allows the user to directly connect to internet streaming services. If you are a producer, engineer or artist who broadcasts to the internet, you can do this with pristine audio quality via the 32Ci.

The 32Ci features a range of controls including low and high pass filters. The filters are taken from the 32C console and are extremely high-grade tools – extremely useful in treating the signal at source, such as a cutting very low frequencies in
a vocal (for example, cutting at 80Hz), or significantly reducing the shimmer of cymbals, (with a cut at around 12-14KHz, for example).

The bump button engages a slight resonance at the cutoff frequency of the high-pass filter (only). This helps retain some of the perceived bass energy, while still filtering out unwanted frequencies below the cutoff frequency. The ‘bump’ button was not included in the original design of the 32C console, but was a common modification, thereafter.

There are two rotary knobs that control the monitoring of the two main inputs; the user may blend the signal and select their ‘sweet spot’ between the direct signal
(i.e. the signal that is going in to the device) and the PC (the signal that is coming out from the computer). Below this, the headphone volume knobs are conveniently placed, for both headphone outputs.
A sturdy high-grade monitor knob complete with responsive LED metering indicators and pad, instrument, +48K phantom power and polarity change buttons for each 32C preamp sit atop the device. Users will notice the expensive feel of the buttons and knobs – all switchgear is manufactured to a very high specification.

Switchable monitoring allows the engineer or producer to quickly check mixes
on alternative speakers, allowing the user to switch between professional- grade monitors (+4) and domestic-grade speakers (-10). This is easily achieved via
the ‘Alternate’ button. If secondary monitors are not fitted, the ‘Alternate’ button effectively becomes a convenient ‘Mute’ button.

A super fast and reliable chip, ARM-M7/500MHz is used internally for extremely stable signal processing – two instances of the chip are used, one for the USB connection and one for mobile devices via the independent Type-C connector at the rear.

The Harrison 32C workflow is available at the mixing stage as well as the recording stage with the included Harrison Vocal Intensity Processor and AVA Live plug-ins, all modelled from the same hardware technology as the 32C console. Please ensure you download and install these excellent plug-ins at your first available opportunity

Top Panel

1. Inst. switch

   • Switches the “Mic/Instr” 1/2 input to the dedicated hi-z instrument input instead of the XLR/Mic +48v input.

2. Polarity switch

   • Inverts the polarity of the channel’s signal. Generally, this function is used to fix phase cancellation problems.

3. +48V phantom power switch

   • Press to supply +48V phantom power to the associated XLR input. This phantom power circuit is suitable for most condenser microphones.

4. Pad switch

   • This attenuates the signal by 20dB, before it reaches the mic preamp circuitry inside the 32Ci.

5. Gain control

   • This potentiometer controls the gain of the input of the selected channel.

6. ‘In’ button

   • Selecting the ‘In’ button will engage both the High Pass Filter and Low Pass Filter, which matches the operation of the original 1970’s era Harrison 32C console. If the button is disengaged then the filters (and bump) have no effect on the signal.

7. LP Button (Low Pass Filter)

   • A circuit that only passes signals below its cutoff frequency, selectable with the LP knob, while attenuating all signals above it.

8. HP Button (High Pass Filter)

   • A circuit that only passes signals above its cutoff frequency, selectable with the HP knob, while attenuating all signals below it.

9. ‘Bump’ Button

   • This engages a slight resonance at the cutoff frequency of the high-pass filter
     (only). This helps retain some of the perceived bass energy, while still filtering out unwanted frequencies below the cutoff. The ‘bump’ button was not provided on the original 32C analog console, but was a common modification, thereafter.

10. PC/Direct Knob

    • This knob blends the signal from the PC and the input to the 32Ci.

11. Headphone volume controls

    • Connect one or two pairs of stereo headphones to the two 1/4 ” TRS jack sockets and adjust the volume with these knobs. The headphone outputs should be routed to analogue outputs 1/2 and 3/4 respectively (as stereo pairs).

12. Master knob

    • This knob controls the volume of the main output 1/2, unless the ‘Alternate’ button is selected, in which case the knob will control outputs 3/4, (if no monitoring is set up for outputs 3+4, the ‘Alternate’ button effectively becomes a ‘Mute’ button). The surrounding LED lights provide responsive Left + Right channel metering, (in six segments indicated by the LEDs, (-20dB, -10dB, -6dB, 0dB, +6dB and +10dB). This metering shows the level for the ‘monitor mix’ being sent to the speakers, i.e. it shows the combined level of the direct inputs and PC playback.
    • Note : if you turn the mix knob all the way to ‘direct’ and speak into a mic (or use instrument or line-in sources), the user can benefit from the level meter for setting the mic/instrument/line in input level.

13. Alternate button
    Select this button to switch between two separate monitoring options via outputs 1/2 and output 3/4. The Main output level (1/2) is ‘+4’, intended for ‘pro level’ speakers. The ‘Alt’ output has an output level of ‘-10’, which is better for a consumer system and/or a speaker which have a limited trim range and are too loud when fed a ‘+4’ signal.

Rear Panel

1. Power supply connector
   A +12V DC power supply adapter is required to power the 32Ci (supplied).
   (Note: You can purchase replacement power adapters from ICON distributors/dealers near you)

2. USB connector (Type C)
   Connect it with the provided USB cable (Type C) to your Mac/PC/iOS device camera kit’s USB connector. Your Mac/PC must have a USB 2.0 connector in order to run the full speed of the 32Ci.

3. Mobile Out (Digital – Type C & Analog – 3.5mm TRRS)
   These ports allow you to connect your smart device and your Mac/PC simultaneously, so you may process the audio signal with your Mac/PC before delivering a signal to the smart device for live streaming applications.
   Digital – Type C jack for connecting directly to the digital jack of the smart device (OTG adapter required)
   Analog – TRRS stereo jack for connecting directly to smart device’s audio I/O

4. ADAT I/O
   Connect your ADAT-equipped device here via an optical cable with Toslink converters for up to 8 channels.

5. MIDI I/O connectors
   MIDI input and output standard 5-pin DIN connectors.

6. Outputs
   MAIN L/R – These are balanced analog outputs on 1/4″ balanced TRS connectors at +4dBU line level. These o

   • ALTERNATE L/R – These outputs can be connected to a pair of alternate utputs that should normally be connected to your main monitors, (this connection is designed for ‘pro’ level monitors). monitors. The alternate monitoring option is triggered by pressing the ‘Alternate’ button. If no alternate monitoring
     is connected, the ‘Alternate’ button effectively becomes a ‘MUTE’ button for the MAIN L/R monitors, when it is pressed.

   • Note: The Main output level is ‘+4’, intended for ‘pro level’ speakers. The
     ‘Alternate’ output has an output level of ‘-10’, which is better for a consumer system and/or speakers that have a limited trim range and/or are too loud when fed a ‘+4’ signal. If you only have one pair of speakers, you can use the connection that makes the most sense for your setup and the alternate button effectively becomes a mute switch.

7. Inputs 3+4
   These are balanced analog inputs on standard 1/4″ balanced TRS connectors, switchable between ‘+4’ and ‘-10’ (via the adjacent button). The ‘+4’ setting is preferable for a professional device (like the output of a high-end mic preamp), while the ‘-10’ setting is more suitable for a consumer device.
   One of the expected uses of the line input 3+4 is for a keyboard synth or a drum machine. In this scenario, the ‘-10’ switch serves to provide more suitable gain for say, a synth, allowing it to be better level-matched with the mic/instr inputs by using the knobs on the front panel. See the real world example on page 15.

8. +4/-10 switch
   This button allows you to select the input sensitivity between ‘-10’ and ‘+4’
   for line inputs 3+4, as described above. The switch affects both inputs 3+4 simultaneously.

9. “Mic/Instr” Inputs 1/2
   These are unbalanced instrument and balanced mic level inputs, connected to the 32C pre-amp. These hybrid connectors will accept a standard 3-pin XLR plug or a 1/4” TS connector. The inner 1/4″ connector is ONLY for Hi-Z instrument- level input, and the XLR is intended for microphones.
   With the ‘Instr’ switch selected, the pre-amp will switch to the dedicated hi-z instrument input instead of the XLR/Mic +48v input.

   • Note: Regarding line-level inputs, (i.e. sources from mixers, CD players and so on), the best option is to use the dedicated balanced line-level input connectors at the rear of the device.
     Alternatively, it is possible to use the balanced XLR inputs with the PAD engaged. A line-level signal connected to the XLR will have slightly higher noise due to the mic preamp gain. However, this does allow the user the benefit of adjusting level control, polarity and filters. However, on the whole, the ‘instrument’ 1/4″ plug is not recommended for connection to a line- level source.

A Brief Explanation of the Differences Between ‘Line in’ and ‘Instrument Inputs’

“Line in” and “instrument in” are two types of inputs found on audio interfaces, and they differ in terms of the type of signal they can receive.

A line-in input is designed to receive a line-level signal, which is a signal that has been pre-amplified and has a higher voltage than an instrument-level signal. Line-level signals are typically used for sources such as mixers, CD players, or other audio playback devices. The line-in input is usually a balanced input that accepts a TRS (Tip-Ring-Sleeve) connector.

An instrument input, on the other hand, is designed to receive a lower-level instrument-level signal. This type of signal is generated by instruments such as guitars, basses, keyboards, and other electronic instruments. Instrument- level signals are usually unbalanced, meaning they have a single signal wire and a ground wire. The instrument-in input is usually an unbalanced TS (Tip- Sleeve) connector.
In summary, the main difference between line-in and instrument-in inputs on an audio interface is the type of signal they can accept. Line-in inputs are designed for line-level signals, while instrument-in inputs are designed for instrument-level signals.

Using Inputs 3/4 and the -10/+4 switch

Real-world Example:

Sean is using a drum machine on inputs 3+4. Sean can barely hear it, above the level of the high-gain microphone inputs, because the drum machine’s output volume is relatively low in comparison. Sean unplugs the drum machine safely, selects the -10 switch and plugs the drum machine back in, (ensuring the Master knob & headphone volumes are turned down first to protect ear safety). The -10 switch tells 32Ci that it needs to give the line inputs an extra ‘boost’ to help them compete with the high-gain mic and instrument inputs. Sean can now make a better job of balancing the inputs 3+4 against inputs 1+2 with the ‘Gain’ knobs on the top panel.

Front Panel

Note: When the -10 (consumer-level) switch is engaged, the input signal is expected to be unbalanced. With the switch in the +4 position, the input signal is expected to be balanced.
This matches the expected behavior of consumer vs pro equipment.

1. Headphone output

This output jack accepts a standard 1/4″ stereo TRS headphone connector. Headphone Output 1 is fed by DAW Mix 1/2 (the main output of the DAW).
Headphone Output 2 is fed by DAW Mix 3/4, which means you can effectively have two different DAW mixes and PC/Direct blends for each Headphone user,(particularly useful if, for example, Headphone User 1 user is an engineer and Headphone User 2 is a singer).

Hardware Connections

Connect the 32Ci Analog Mic Preamp with Audio Interface outputs to your amplifier, powered monitors or surround system. The default outputs are channels 1 and 2. You may select an alternate monitoring set-up using Alternate stereo outs (3/4).

The main outputs (1/2) are +4 and are suitable for pro-level speakers. The alternate outputs (3/4) are -10 and are best suited to consumer speakers or speakers with a limited trim range and/or are too loud to be fed the +4 signal.
If you are monitoring through headphones, connect your headphones to the device’s headphone output. HP output 2 is fed by DAW output 3/4 only.

Connect your microphones, instruments or other line-level analog sources to the device’s analog inputs. Ensure the +48V switch is turned OFF for microphones that do not require Phantom power.

Different types of microphone connection method diagram

Note: For dynamic microphone users, please make sure +48V phantom power switch is “OFF” before you plug in your microphone, otherwise it may cause damage to your microphone.

OTG Connection

“OTG” connectivity is available via the 32Ci.

“OTG” stands for “On-The-Go”. It refers to a feature available on many modern smartphones and tablets. OTG allows these devices to act as “hosts”, enabling them to connect and interact with various USB peripherals. The 32Ci’s ‘OTG’ capability allows the user to broadcast on social media, taking advantage of the 32Ci’s superb audio capabilities.

In order to use this feature, a special ‘OTG cable must be used – a standard
USB cable will not work. ‘OTG’ cables have an additional pin in the mobile phone connector, which allows the device to act as a ‘host’.

1. Ensure that your smartphone or tablet supports OTG functionality. Most newer Android devices support OTG, but it’s always a good idea to verify this in the device specifications or manual.
2. Obtain an OTG cable – you will need an Apple Camera kit to connect.
3. Turn on the 32Ci. Connect the 32Ci via the USB C port.
4. Plug the other end of the OTG cable into your mobile or tablet’s charging or data port. Your device should recognize the 32Ci automatically.
5. Launch your chosen streaming or recording application on the device.
6. Check to see if it is receiving audio from the device. You should be able to hear the output of the 32Ci on your phone/device and/or see the signal of the output (depending on the app you are using).
7. Start streaming – the audio output from the 32Ci will be reflected in your broadcast.
8. When you have completed your broadcast, safely eject the 32Ci. You can usually find an option to eject or safely remove USB ‘peripherals’ in the settings or notification panel of your device.

Please note that the above steps may vary slightly depending on your mobile/tablet device’s manufacturer, model, operating system version, and streaming application. Additionally, not all mobile and tablet devices are guaranteed to work with OTG, as some may require specific drivers or have compatibility limitations.

Please note that the Apple Camera kit device is required when using the OTG connection.
