Audient iD22 AD/DA Interface & Monitoring System The iD22 is a Mac OS-compatible, USB-based audio interface and monitoring system featuring a two-input, six-output, 24-bit/96 kHz capable AD/DA with ADAT optical I/O and a number of attractive features. Those include two superb Audient discrete, Class A preamplifiers with +48 VDC phantom power, -10 dB pad, polarity flip, HPF (-3 dB @ 100 Hz) and two balanced quarter-inch TRS inserts (perfect for those of us with favorite analog outboard). The iD22 ($995) is housed in thick aluminum—robustly built.
The intuitive Monitor/Mixer application is ideal for building monitor mixes with dual stereo cue mixes (round-trip monitoring, in to out, is 6.33 mS at 44.1 kHz sampling with a 32 sample buffer). Included are assignable talkback, three assignable and customizable function buttons, dim and alternative output controls, and a large, solid-feeling monitor level knob in the middle of an incredibly well-conceived, ergonomically comfortable design.
The iD22 is small enough (roughly 7” by 9”) to reside discreetly on your desktop. It features retro-influenced HiFi-style knobs, switches and backlit buttons, with a design scheme and overall aesthetics very complimentary to Apple’s Mac Book Pro. According to Audient, Windows OS compatibility for the iD22 is on the horizon and iOS compatibility will follow.
The iD22 will serve most self-recordists’ interface needs most of the time. This is certainly true for those that build productions one input, or stereo pair, per take. For me—a regular recordist of multiple-input analog sources (drum kit, multiple room-miked acoustic instrument configurations, etc.)—the iD22 alone wasn’t always enough. Wisely, Audient has included ADAT optical I/O, which allows users to expand to a total of 10 analog inputs with full access to iD22’s system software routing and mixing capabilities (96 kHz operability will limit outboard analog inputs to a total of six). Audient recommends its (excellent) ASP008 8-channel, variable impedance microphone preamplifier for expansion, though I used a Focusrite Scarlett 18i20 connected via ADAT to the iD22.
I was thrilled to find the two balanced insert points, one per input channel, on the iD22—a unique feature for a small I/O such as this. Like many, I compress while tracking and already own a few analog processors I prefer to use.
The built-in Audient preamps sound superb and crystal clear with high headroom. The GUI is so intuitive that I hardly glanced at the iD22’s PDF manual, referencing it only when I had routing questions. The software install was glitch-free too. I’ve used a variety of USB-based multi-featured I/Os, and the iD22 is currently my favorite. For those wanting a unique edge in this on-the-go, ITB-mixing world, grab an iD22 I/O and hit the ground running.
