Audient iD4 MKII - USB-C Audio Interface

Audient iD4 MKII is a compact USB-C audio interface with low latency, featuring 24-bit/96kHz AD/DA converters, a Class A mic preamp, JFET instrument input, dual headphone outputs, monitor mix functionality, ScrollControl mode, and 48V phantom power. It's one of the best entry-level interfaces for guitarists, home studios, podcasts, streaming, and music production.

It includes the same Audient Console Class A mic preamp found in the flagship ASP8024-HE recording console, delivering clean, studio-quality analog sound with ultra-low noise and distortion. The JFET DI input simulates the input stage of a tube amp, allowing guitars, basses, and synths to be plugged directly into the interface with rich harmonic character.

The dual headphone outputs (3.5mm and 6.3mm) are powered by a strong headphone amp capable of driving up to 600-ohm headphones. The Monitor Mix function provides near-zero latency monitoring by blending input signals with playback from the DAW. ScrollControl mode transforms the volume knob into a virtual scroll wheel for controlling DAW and plugin parameters. The interface is fully compatible with iOS devices and built for portability with its rugged all-metal construction.
