The Audient iD4+ is a 20-in / 24-out desktop audio interface built for the engineer running high-channel-count tracking and hybrid sessions. Four Audient Console Mic Preamps deliver 75dB of clean gain with Smartgain, backed by 32-bit conversion and 128dB of dynamic range over bus-powered USB-C. Two features set it apart in its class: built-in RoomTune™ Monitor Correction, with the RM1™ Reference Microphone included, and tone-shaping preamps that add real analogue saturation, all handled in hardware.
Balanced hardware inserts on channels 1 and 2 bring outboard compressors and EQs into the path ahead of the DAW, while 16 channels of ADAT input and output take the system to 20 inputs for a full band or drum kit. The Analogue Tone Suite shapes the preamps on the way in: HMX adds warmth through a discrete MOSFET circuit, LIFT adds sheen, GLOW combines the two, and ORBIT offers Punch, Smooth and Vintage voicings. Two headphone amplifiers support up to four artist mixes.
