Microphone Preamplifiers
& Line Inputs
iD22 features two classic audient
microphone preamplifiers.
The design features an 8-transistor
discrete class-a front-end providing
exceedingly low distortion and noise
performance. From a sonic point of
view, iD22 is fast, open and detailed.
All analogue circuitry runs on +/-15V
Hardware Features
(30V rails) and provides high headroom
and class leading drive capability compared
to other similar interface products.
The microphone preamplifiers feature:
• 60 dB of clean gain
• 48v phantom power rated at 10mA/
channel
• > 3kΩ input impedance which provides
a punchy tone from any microphone
transducer type
• -10 dB pad for increasing input headroom
• Polarity reverse (always check
phase when recording with multiple
NeutrikTM XLR/TRS Jack combi-connectors

with freedom from overload.
microphones)
• Switchable (fixed frequency) 100Hz
12 dB/octave high pass filter for rumble

11
Hardware Features
Instrument Input
iD22 employs a discrete class-a JFET
instrument (D.I) input on channel two.
Plugging in a TS (tip-sleeve unbalanced)
jack will override the mic signal and turn
channel two into a fully fledged, fantastic
sounding instrument input with access to a
-10 dB pad (for hot output instruments such
as active basses, drum machines and
synthesizers), polarity reverse (useful for
phase alignment between a mic and D.I) and
the HPF (useful for taming unruly low
frequency content).
Balanced Inserts Send & Return
Once signal has passed through the
microphone preamplifier and input
conditioning stage - it is provided at
a balanced insert send jack.
Both input channels feature impedance
balanced insert sends and electronically
balanced insert returns before the AD
converter.
These console-style insert points make it
very easy to add your favourite processing

much of the competition.
Insert your favourite compression and EQ
here to build vocal chains that rival the very
best. Rest assured the mic pre in iD22 will
stand up to many outboard units costing
several times more than the entire unit!
Insert Normalling
Insert send & return jacks use normalling
connectors and therefore do not need to be
patched when not in use.

Hardware Features
Patching Inserts
To incorporate your favourite
processing prior to conversion, simply
patch the iD22 insert send into your
processing chain and take the output
of the last device in the chain and patch
back into the insert return on iD22.

Direct Access to ADC
The insert return connection on iD22 is a
very pure electronically balanced input stage
that directly drives the analogue to digital
converter stage (ADC).
As such this is a great place to return
signals directly into the ADC ensuring
minimal signal path colouration.

Hardware Features
Assignable Line Outputs & DACs
iD22 features four assignable line / DAC
outputs. These can be used to create many
useful routing options for both tracking and
mixing.
Output assigns take place in the iD mixer
application System Panel (see page 27 for
details accessed in the Master Section).
Here a selection of radio buttons allow
outputs to be fed from either the iD DSP
mixer main output, the iD mixer cue outputs
(A or B), an alternative loudspeaker output
Typical Output Routing
In traditional style tracking situations with
separate engineer and artist(s) mixes,
outputs 1+2 would likely be set to Main Mix
to provide output to control room speakers.
Outputs 3+4 can be set to feed a cue
mix (from Cue A or B) to external headphone
amplifiers in either ganged stereo or dual
mono.
iD22’s built in headphone output (5+6) could
be used as a 2nd reference for the engineer
(set to monitor the Main Mix) or as an
or directly from your DAW (bypassing the iD
DSP mixer by paralleling the input straight to
the DACs).
alternative and independent headphone mix
for an artist (set to Cue A or B).
If you prefer to balance all headphone mixes
from inside your DAW (at low buffer sizes to
minimise latency) then selecting DAW Mix
for outputs 3+4 and 5+6 would allow your
DAW to directly address the DA converters
and outputs without passing through the iD
DSP mixer (note the mixer is still active).
In traditional mixing situations, outputs
1+2 would be set to monitor the Main
Mix (taking advantage of the DSP monitor
controller functionality in iD22. Outputs 3+4
can be set-up as an alternative speaker
destination (main/mini etc) and headphones
(5+6) can also be fed for reference.

DAC & Line Output Routing Ideas
Hardware Features
iD22 provides some very flexible output
routing and these are best demonstrated
in diagram form.
Using iD22 for Monitoring & Tracking:
All four line outputs are electronically
balanced using the same topology as our
famous console, the ASP8024.
Expect plenty of output drive (>18 dBu),
good noise rejection and a balanced output
impedance of <100Ω.

Hardware Features
Headphone Output
iD22 features a high current headphone
amplifier which is fed by it’s own separate
DAC. This can be used for reference
monitoring, to provide artist headphone mix
or to drive a small set of loudspeakers from
an unbalanced Y-split cable.
The headphone amplifier can be fed from a
number of sources as set in the Routing
Matrix found in the System Panel of the
iD mixer application (see previous pages
or the section found on page 29 for more
info).
Digital Inputs / Outputs
To complete the i/o package, iD22
features an optical input and output
connection. These can be set to operate as
stereo optical S/PDIF or 8-channel ADAT
via the System Panel in the iD mixer
application. Both formats will operate at up
to 96kHz sample rate, with ADAT dropping
to 4-channels at rates above 48kHz.
Running in S/PDIF mode, the optical i/o
provides the option to integrate an audient
MiCOTM for 4-channels of audient micpre, or
an external reverb for monitoring.
A front panel potentiometer provides
digitally calibrated and perfectly matched
stereo volume control over the headphone
output.
Running in ADAT mode, the optical i/o
provides a great way to expand to 10-inputs
via an audient ASP880TM for recording.
The ADAT outputs could also be connected
to headphone distribution systems such as
a HearbackTM HUB or to an 8-channel DAC
for summing purposes. We designed iD22
to grow with your needs.
For more information about setting up
sample rates and system clocking please
refer to pages 27 and 33 onwards.

Hardware Features
Monitor Control
iD22 provides all of the excellent
monitor control functionality as found
on one of our consoles.
As such, it is possible to control main and
alternative loudspeaker volumes with
a perfectly matched stereo volume control
on the main unit.
The MONITOR knob is solid aluminium and
feels expensive - which is just the way it
should be when you will touch it every day.
Monitor Control Features
• Volume control (perfectly matched)
• Alt. Loudspeaker with programmable
level (assignable to an ‘F’ key)
• DIM with programmable level
• CUT
• Mono Sum (assignable to an ‘F’ key)
• Polarity reverse (assignable to an ‘F’ key)
• Talkback (assignable to an ‘F’ key)
By using polarity reverse and mono sum
it is possible to listen in sum or difference
(mid or side) modes. This provides an
excellent way to check mono compatibility
There is no signal degradation in this
volume control and stereo image will
not wander about at various listening
levels - the image will be rock solid.
Accompanied by this monitor volume knob
are permanently assigned hardware DIM &
CUT switches.
The level of DIM and ALT. Loudspeaker trim
can be adjusted in the iD mixer application
(System Panel).
Alongside these functions, three user
programmable ‘F’ keys provide access
and to also learn spatial tricks from your
favourite reference material. Please see

Hardware Features
Hardware Metering
4-segment hardware LED metering
can be found on the main panel of
iD22.
This meter is peak reading and calibrated
to the digital recording medium.
iD22 converters use a standard calibration
level of 0dBu = -18dBFS, or perhaps more
importantly +18 dBu = 0dBFS.
It is suggested that end users observe
their DAW metering for recording levels,
Switch Operation
All hardware push switches (DIM, CUT etc)
feature momentary operation if pressed and
held or latching operation if pressed and
released quickly - very useful!
Kensington Lock
For those of you who work in educational
establishments or in situations where your
equipment is public facing and subject to
possible theft opportunities, we have added
a Kensington lock hole to the chassis to
enable you to protect your iD22.
hence currently the iD22 hardware meters
indicate playback level in the main mix
bus of the iD mixer application.

Input Channels - Channel Types
Software Features
The iD mixer application features three
types of input channels, these are colour
coded and are as follows:
• Analogue (Inputs 1+2) - BLUE
• Digital (S/PDIF or ADAT) - GREEN
• DAW Mixes (Playback 1-6) - PURPLE
DAW inputs are provided as three stereo
pairs and are designed as ‘virtual’ playback
channels from your DAW.
These can be monitored via the onboard
DSP mixer, routed to cue mixes or hard
assigned to DAC outputs.
Addressing outputs in your DAW will feed
signals into these channels. Therefore iD22
can sum all three signals together for
monitoring and access to cue mix buses.
Channel Naming Strip
Analogue input channels are taken
directly from the two ADC (insert returns,)
signals available here are; microphone, line,
D.I (channel two) or unity gain line input at
the return jack.
Digital inputs are provided as two
channels in S/PDIF mode and eight

Software Features
Channel View Settings
When tracking (without using a digitally
expanded iD22) it is most likely that the
following channel view (Analogue + DAW)
would be the most useful, enabling you to
see mic/line inputs and DAW returns:
Volume Control
The output of the iD DSP mix bus is sent
to whichever output is set-up as Main Mix
in the Routing Matrix. This is your monitor
destination and should be connected to
your main studio loudspeakers.
To control the monitor volume of this
output, use the hardware knob on the
main unit.
For simple monitoring /
listening or ITB mixing it
may be cleaner to view
just the master section.
Or when fully expanded
via ADAT with something
like an ASP880, you can
view all channels (after
10 mono slots, a scroll
bar appears).

Programming ‘F’ Keys
(Monitor Control Functionality)
There are several functions that can be
assigned to the hardware ‘F’ keys.
∑ Mono Sum
In order to check your mix for mono
compatibility (still important for DAB
radio and laptop / ipad users) either use
the Mono Sum button in the iD software
or assign it to an ‘F’ key by right clicking.
Software Features
Polarity Reverse
By pressing the polarity reverse button,
the left channel of the stereo mix is
inverted. When combining this with the
right channel using the mono sum feature
in conjunction with the polarity reverse
function - a L-R sum is created instead of an
L+R sum. This will cancel the centre (sum)
of the stereo signal and leave behind the
difference signal (L-R). Monitoring this
provides a great way to listen to stereo
content such as reverbs and also pick up
tricks from your favourite mix engineers.
It is a very useful and different perspective
ALT Alternative Loudspeaker
To set-up an alternative loudspeaker
for greater monitoring flexibility - a pair of
outputs must be assigned as a source to
the alternative pair in the System Panel.
These outputs can be digital via S/PDIF or
ADAT or indeed analogue via DAC3+4 or
DAC5+6.
ALT can be used to turn on headphones
if DAC5+6 is selected as the headphone
source, alternatively you can feed loud-
speakers with DSP control and digital inputs
of the mix balance.
Talkback - see page 28 for more
information.
via optical S/PDIF.
However in most standard set-ups,
DAC3+4 would be the most likely source.

is located on the talkback
channel which can be used
to trigger talkback whilst
setting up the software mixer.

a talkback microphone in Input 2, however
any of the digital inputs could also be used.
You can assign the talkback
switch to an ‘F’ key in the
master section.

Output Routing Matrix
The routing matrix allows you to patch
the following iD DSP mixer outputs to the
physical DAC outputs (1-6) or the optical
digital outputs (1-8 in ADAT mode or 1-2
in S/PDIF mode).
Software Features
Stereo or Mono
Path Link Button
Headphones are

Output Sources from either
DSP mixer or DAW direct
(mixer bypass)
Output Destinations
Analogue / Digital
In the above example, DAC outputs 1+2
are setup as a stereo pair fed from the iD
(cue masters are mono summed prior to
routing to the DAC outputs). This would
be used to feed an external headphone
amplifier to provide two mono artist mixes.
Naturally a stereo cue mix could be created
DSP mixer main output. This is the default
main monitor path and would feed your
loudspeakers. The iD mixer main output
passes through all monitor control
functionality (mono sum, polarity reverse,
dim, cut and monitor volume).
DAC outputs 3+4 are set as two mono
paths and fed individually by mono Cue A
and B mixes. In this scenario note that cue
pans controls have no effect
by clicking on the stereo/mono path button
and selecting Cue A or B as a source.
Note the flexibilty here, as a stereo Cue A
mix is feeding the iD22 headphone output
(DAC 5+6). Alternative speakers can also
be set-up here (typically DAC 3+4).
By selecting DAW Mix the iD DSP mixer is
bypassed and signals are effectively ‘hard-
wired’ from DAW to DAC.

following the steps detailed on page 6 of
this manual, launch Logic Pro and check the
following:
Logic Pro > Preferences > Audio
If you are using iD22’s onboard DSP mixer
to monitor input signals while recording, be
sure to disable Logic’s software monitoring
to avoid phasing as the same source will
be heard twice with a short delay between
the low latency DSP signal and the delayed
software monitoring signal.
Assigning I/O
All of iD22’s input and output channels will
be available to Logic for routing. There are
a total of 10-inputs and 14-outputs
reported from the driver.
Ensure that iD22 is selected as the active
audio device and here you can set buffer
sizes to affect system latency. If you are
experiencing issues with playback stability
and CPU loading, try increasing the buffer
size to > 256 samples.
