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 regular operation of iD4.
REGISTRATION AND FIRMWARE UPDATE
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

12
Microphone Preamplifier
& Line Input
iD4 features a single classic Audient
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.
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.
HARDWARE FEATURES
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

13
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 synthesisers. The JFET circuitry
adds a tiny bit of colour and distortion to the
signal, giving your instruments a bit of added
warmth.
HARDWARE FEATURES
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.

14
HARDWARE FEATURES
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 off monitoring in your Digital Audio
Workstation (DAW), otherwise you will end
up hearing an extra copy of the signal.
When you rotate the mix into the white
segment, it allows you to monitor the true
input levels where 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.

15
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.
HARDWARE FEATURES

16
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 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.
HARDWARE FEATURES
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.
