Audient ID4+ MK3

From the iD44 to the iD4+ MK3: a desktop interface designed for ambitious sessions

Presented as the interface formerly known as the iD44, the Audient iD4+ MK3 brings together, in a desktop format, features usually spread across several studio devices. Preamplification, analogue coloration, integration of external devices, DSP processing and monitoring correction all contribute to a single workflow chain.

Its purpose is clear: to provide a USB-C audio interface capable of supporting multitrack recording and hybrid setups, without filling the desktop with multiple devices. The combination of RoomTune, the analogue suite and the onboard effects forms the core of this offering, with 32-bit conversion and a sample rate of up to 192 kHz.

For recording a band, producing and mixing in a hybrid studio

The iD4+ MK3 is aimed at sound engineers, producers and musicians who need to go beyond a basic recording setup. Its four preamps allow you to build a multi-microphone recording setup, while its ADAT ports pave the way for additional sources using compatible external converters or preamps. You can therefore develop a system suited to recording a band or a drum kit.

The two JFET inputs directly accommodate instruments on channels 1 and 2. On these same channels, the balanced inserts allow hardware processing to be integrated into the recording chain. For musicians, the two independent headphone amplifiers and support for up to four artist mixes make it easier to organise monitor mixes during sessions.

A complete audio chain, from recording to monitoring control

Four Console preamps and genuine analogue coloration

The four Audient Console microphone preamps offer 75 dB of clean gain and the Smartgain function to make level adjustment easier. You can opt for a transparent capture or shape the signal from the moment of recording with the Analogue Tone Suite, which affects the sound of the preamps and provides genuine analogue saturation.

HMX adds warmth through a discrete MOSFET circuit. LIFT adds brightness, while GLOW combines both treatments. ORBIT offers another approach to the unit's sonic character, with three settings named " Punch ", " Smooth " and " Vintage ". This allows you to adapt the texture of the recording to the source and musical intent, rather than systematically postponing these choices until mixing.

Hardware inserts and ADAT expansion to grow your studio

The two balanced hardware inserts on channels 1 and 2 make room for compressors, equalisers and other external processors in your recording chain. This architecture is particularly well suited to hybrid studios, where analogue tools complement work in the digital audio workstation.

The 16 ADAT channels available in each direction complement the analogue connections to provide a stated overall capacity of 20 inputs and 24 outputs. This connectivity headroom makes it possible to plan larger sessions without giving up the desktop format.

DSP effects for recording and RoomTune for monitoring

The onboard equalisation, compression and reverb benefit from DSP hardware acceleration. Advertised as latency-free for these processes, these effects allow you to prepare a polished session monitoring mix without relying solely on the computer's plug-ins. This distinction is important during recording, when monitoring comfort directly influences performance.

The RoomTune monitoring correction uses the included RM1 reference microphone to account for the influence of the room. It helps limit monitoring coloration for more reliable mixing decisions. The two stereo monitor outputs and dedicated hardware controls complete this monitoring station.

Finally, the interface works with Mac and Windows and retains all its performance when powered via USB-C bus power. No mains adapter is required—a practical advantage for keeping your workspace uncluttered or moving your setup.
