Audient iD4+ – Four Preamps on the Desk

The iD4+ is the largest of Audient's third-generation iD interfaces: four Audient Console Mic Preamps, two front instrument inputs, two independent headphone outputs and dual optical I/O for up to 20 inputs and 24 outputs. It takes over from the iD44 MK2 and ships with the RM1 Reference Microphone for RoomTune correction. At Soundium it is the desktop interface for a band room or a studio that records people, not just parts.

Key Features

• Four Audient Console Mic Preamps: 75 dB of clean gain each, with inserts on channels 1 and 2.
• 20-in / 24-out: Two optical inputs and outputs for up to 16 extra channels each way.
• Two headphone outputs: Separate mixes for the performer and the engineer.
• RoomTune with RM1 included: Room measurement and stereo speaker correction in onboard DSP.
• Analogue Tone Suite: Orbit, HMX, LIFT and GLOW, with every setting recalled digitally.
• BNC word clock output: Locks external converters and preamps to the iD4+.

Customer Benefits

Four preamps is the point where a desktop interface stops being a personal tool and starts running sessions: a drum kit on four mics, a band demo live, a podcast with guests. The two headphone amps mean the singer gets their own mix without a separate amplifier, and dual optical I/O takes two 8-channel preamps when the room needs more. Zero-latency EQ, compression and reverb keep the cue mix comfortable, while RoomTune and the included RM1 take care of what you hear in the control position.

Pros & Cons

✅ Pros:

• Four console preamps in a desktop footprint
• Two headphone outputs for independent cue mixes
• Dual optical I/O reaches 20 inputs and 24 outputs
• RM1 measurement mic included for RoomTune

⚠️ Cons:

• Inserts only on the first two channels
• A desktop unit, not a rack interface, so it lives on the desk

When the session has more than two people in it, the iD4+ is where Audient's desktop range gets serious. Find the Audient iD4+ at Soundium.
