Overview

The Audient iD4 MKII is a 2-in, 2-out USB-C audio interface engineered to bring genuine studio-quality recording to home setups, podcasters, and solo musicians. Its standout feature is the Class A microphone preamplifier borrowed from Audient's flagship ASP8024 Heritage Edition mixing console — a preamp design that delivers the kind of clean, detailed, and transparent sound typically reserved for far more expensive interfaces. Combined with new converter technology in the MKII revision, this interface captures audio with impressive clarity and dynamic range.

The switch to USB-C in this second generation brings faster data transfer and reliable bus power, eliminating the need for an external power supply and reducing cable clutter. The all-metal housing weighs just 740 grams and measures 133x120x40.7mm, making it sturdy enough for studio use yet portable enough for field recording or mobile production. Monitor mix and monitor panning functions give you direct control over your monitoring blend, while dual headphone outputs allow for flexible listening. The included software bundle — featuring Steinberg Cubase LE, Cubasis LE 2, Retrologue 2 synth, Twonotes Wall of Sound, and a Loopmasters sample pack — provides everything needed to start recording, mixing, and producing right out of the box.
