Audient iD4+ MK3 USB Audio Interface

Audient iD4+ MK3 — 20-in / 24-out Desktop Audio Interface

The Audient iD4+ MK3 is a 20-in / 24-out USB-C desktop audio interface built around four Audient Console Mic Preamps, 32-bit conversion and built-in RoomTune monitor correction. It replaces the previous iD44 and packs a commercial-grade signal chain into a single desktop unit for solo vocal tracking through full-band recording.

What sets the iD4+ MK3 apart

Two features rarely appear together in a desktop interface: built-in RoomTune with the RM1 reference microphone included, and the Analogue Tone Suite, which shapes the preamp signal before the converters. HMX adds warmth through a discrete MOSFET circuit, LIFT adds sheen, GLOW combines both, and ORBIT offers three variable-impedance voicings — Punch, Smooth and Vintage.

Console-grade preamps and 32-bit conversion

The four Audient Console Mic Preamps share the analogue design used in the flagship ASP8024-HE console, delivering 75 dB of clean gain to drive an SM7B without a booster. Smartgain sets all four channels at once.

• Number of Preamps: 4 Audient Console Mic Preamps — 75 dB clean gain, Class-A design, Smartgain
• Bit Depth: 32-bit — 128 dB dynamic range
• Sample Rate: up to 192 kHz

20 inputs, 24 outputs, all over USB-C

Two JFET instrument inputs model the input stage of a classic valve amplifier, giving amp sims a rich signal. Balanced hardware inserts on channels 1 and 2 let outboard compressors sit in the signal path before the DAW.

• Inputs: Combo XLR/Jack, Insert, Jack 6.3 mm, Optical
• Outputs: Jack 6.3 mm TRS, Jack 6.3 mm TRS Send, Optical, Word Clock
• ADAT / S/PDIF: 16 channels ADAT I/O, S/PDIF via optical

Hardware monitoring, RoomTune, and zero-latency DSP

Two independent headphone amplifiers support up to four artist mixes. Two stereo monitor outputs have dedicated hardware buttons for Mute, Dim, Speaker Switching and Talkback. RoomTune runs on the hardware at zero CPU cost.

• Phantom Power: +48V on all four preamps
• DSP FX: EQ, compression and reverb on hardware — zero latency
• Power: Full performance on USB-C bus power
