Hardware Features

16 17
Microphone Preamplifier
& Line Input
iD4 features an Audient Console microphone
preamplifier. This preamp is based on designs
from Audient’s classic consoles and are 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.
• Amphenol™ 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
Instrument 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 synthesisers. The JFET circuitry adds
a tiny bit of colour 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 how your
mix sounds on headphones, or to provide an
artist headphone mix.

18 19
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.
While mixing in your live input, it is important
to turn o monitoring in your Digital Audio
Workstation (DAW), otherwise you will end up
hearing an extra copy of the signal.
If you rotate the Monitor Mix dial all the way
to INPUT, it allows you to monitor the true
input Levels. The Mic/Line input will appear
on the top meter, and the D.I on the bottom
meter.
Note
Listening on 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 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 being picked up by
the mic or getting feedback.

20 21
Status LED
The white USB 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.
iD Button
Pressing the iD button will activate
ScrollControl, which allows the encoder to
be used as a virtual scroll wheel for your
computer. This works well for compatible
plugin parameters and adding automation
in a more hands on way.
To use ScrollControll, 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 found in your
computer settings.
ScrollControl may act slightly dierently
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
dierent settings on iD4, however when not
adjusting any settings, it will display the peak
output level.
ScrollControl
General Operation

22 23
This next section will give some insight on
how to get the most out of iD4, and some of
the dierent 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 dicates how many times a second
the level of the incoming audio is measured
(sampled), which allows continuous analogue
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.
Buer Size and Latency
Buer size is a very important setting that
will ensure that your projects are running
smoothly and eciently. A wrongly selected
buer size can result in hearing pops, clicks
and stuttering audio. Buer size dictates how
many “samples” of audio are stored before
being sent to the output.
A buer 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 buer
size relatively high to reduce the strain on
your computer. If you are wanting to monitor
through your DAW with eects, for example
being able to hear your electric guitar with an
amp simulator on it, you will want the lowest
buer size your computer can handle. The
buer size you can get down to before you
get audio issues is hugely dependant 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
buer sizes.
For mixing, you can set the buer 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 buer size than normal.
You may need to adjust buer sizes when
working at dierent sample rates to account
for the dierence in CPU requirements of
dierent sample rates.
macOS
The buer size is selected from within your
DAW, most likely in an audio settings or
preferences menu.
iOS
The location of the buer size setting (or
having a setting at all) is dependant 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.
* Setting buer size on macOS in
Logic Pro X
* Setting buer size on iOS in Auria Pro
Windows
On Windows, the buer size needs to be
selected in the iD app before the DAW. A
buer size of 32 samples to 4096 samples
can be selected.

24 25
DAW 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 > Audio
Once iD4 is selected as your device, set the
appropriate buer size for your session. If you
are using the Monitor Mix knob to monitor
your inputs, you can set the buer 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 buer 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 > Audio
If you are monitoring your input signal on iD4,
disable Logic’s software monitoring to avoid
hearing duplicate signals as this can be very
o-putting.
Logic Pro > Preferences > Audio > General >
Software Monitoring
Logic Pro Setup

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
buttons on the audio tracks are not selected,
to avoid duplicate signals.
For more Pro Tools information consult your
Avid user manuals & documentation.
Operation with Pro Tools
If using Windows, ensure that you have
followed the installation instructions found on
page 10.
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 Buer Size settings in
the iD System Tray before opening a project.
Changing these 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.
Pro Tools Setup
Close the VSTdevice setup panel and navigate
to the Audio connections panel:
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 o on the track.
Operation with Cubase / Nuendo
If using Windows, ensure that you have
followed the installation instructions found on
page 10.
With the iD4 plugged into your computer,
launch Cubase or Nuendo and once a session
is open, go to
Studio > Studio Setup
Select VST Audio System in the devices menu.
Then select the Audient iD4 from the
dropdown menu. You will be asked if this is
okay, select “Switch”
Cubase/Nuendo Setup

28 29
If you are monitoring your inputs using the
Monitor Mix knob, then you can keep the
buer size reasonably high to reduce the
strain on your computer. In this case, you also
need to make sure that input monitoring is
turned o on the track in Ableton.
For more information about setting up audio
I/O refer to your Ableton Live user manuals &
documentation.
Operation with Ableton Live
If using Windows, ensure that you have
followed the installation instructions found on
page 10.
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 buer size.
If using Windows, ensure to set the Latency
and Buer Size in the iD System Tray before
changing it in Ableton.
Ableton Live Setup
“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.
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
dierent USB port on your computer and
possibly a dierent USB cable. If you are using
a USB hub, try plugging iD4 directly into the
computer.
“Igetclicksand popsonDAWplayback”
This is most likely to do with setting the
buer 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 buer sizes. Typically
you want small buer sizes for tracking or
recording software synths to keep the latency
low. However when mixing it is fine to set a
slightly higher buer 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:

“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.
