Audient iD4+

The Audient iD4+ is a 20-in/24-out USB-C desktop audio interface with four Console Mic Preamps, 75 dB of clean gain, 32-bit conversion, analogue tone shaping and built-in RoomTune™ Monitor Correction for professional recording and mixing.

Building on the iD44, the iD4+ combines its predecessor’s four-preamp layout, JFET instrument inputs, balanced inserts and ADAT expansion with Smartgain, the Analogue Tone Suite and onboard DSP effects. Audient Analogue Intelligence brings these recording and monitoring tools together in a desktop system for multitrack production and hybrid studio workflows.

Console Mic Preamps with Smartgain

Four Audient Console Mic Preamps provide up to 75 dB of clean gain, accommodating quiet sources and microphones that require substantial amplification. Smartgain automatically sets input gain, helping engineers establish recording levels quickly and concentrate on microphone placement and performance.

Two JFET instrument inputs on channels 1 and 2 provide direct connections for electric guitar and bass. These inputs give instruments a dedicated recording path through the interface without an external DI box.

Analogue Tone Suite

The Analogue Tone Suite shapes microphone signals during recording through four distinct options. HMX uses a discrete MOSFET circuit to introduce warmth and analogue saturation, while LIFT adds sheen. GLOW combines HMX and LIFT for a fuller, more polished sound at the recording stage.

ORBIT offers three microphone voicings: Punch, Smooth and Vintage. These choices give engineers additional control over microphone character, helping them match the recording tone to the source and arrangement.

Balanced Hardware Inserts and ADAT Expansion

Two balanced hardware inserts on channels 1 and 2 integrate external processors into the recording chain. Engineers can connect outboard compressors or equalisers and shape signals before analogue-to-digital conversion, bringing familiar studio routing to a desktop interface.

ADAT connectivity provides up to 16 digital input channels and 16 digital output channels. With compatible external equipment, the iD4+ supports a total of 20 inputs and 24 outputs, accommodating additional microphone preamps, larger recording sessions and hybrid setups. This expansion makes the interface suitable for drum kits and ensemble recording alongside smaller overdub sessions.

RoomTune Monitor Correction with RM1

Built-in RoomTune™ Monitor Correction works with the included RM1™ Reference Microphone to assess the monitoring response and compensate for the room’s influence on tonal balance.

This correction helps engineers make more dependable EQ and balance decisions at the listening position. By reducing monitoring colouration, RoomTune supports more consistent mix translation across other playback systems.

Onboard DSP EQ, Compression and Reverb

Hardware-accelerated DSP runs EQ, compression and reverb inside the interface, supporting direct monitoring without DAW buffer latency. EQ adjusts tonal balance, compression controls dynamics and reverb adds ambience to the performer’s monitoring experience.

These onboard effects help musicians hear a more developed sound during tracking while the interface handles the processing.

Independent Headphone Mixes and Monitor Control

Two independent headphone amplifiers provide separate listening outputs, while support for up to four Artist Mixes allows different balances for performers. Engineers can prioritise vocals, instruments or backing tracks according to each musician’s monitoring needs.

Dual stereo monitor outputs accommodate two pairs of studio monitors. Dedicated hardware monitor controls keep essential listening adjustments within reach during recording and mixing.

32-bit Conversion and USB-C Bus Power

The iD4+ combines 32-bit conversion with a specified 128 dB dynamic range for detailed recording and monitoring. Support for sample rates up to 192 kHz accommodates high-resolution production workflows.

USB-C bus power delivers full performance through a single connection without an AC adaptor, simplifying desktop installations and mobile recording setups. Mac and Windows compatibility allows the interface to work across both platforms.
