Hardware Features
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
(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
microphones)
• Switchable (fixed frequency) 100Hz
12 dB/octave high pass filter for rumble
removal
Neutrik TM XLR/TRS Jack combi-connectors
provide microphone and line inputs. The line
inputs are padded through the microphone
preamplfiiers and have access to the pad,
polarity reverse & HPF functions, therefore
accommodating a huge range of input levels
with freedom from overload.
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
prior to conversion - setting iD22 apart from
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.
Capture great tone
just by plugging in direct!
