⭐⭐⭐⭐⭐ (9.0/10)
Sound Quality
The iD4 MkII records at up to 24-bit/96kHz with Audient’s renowned console-grade mic preamp, delivering a clean, transparent sound that rivals more expensive gear. The preamp offers up to 58dB of gain, making it ideal for dynamic mics like the Shure SM7B without needing an external booster.
Its JFET instrument input adds analog-style warmth to guitars and basses, emulating the tone of a tube amp’s input stage. Monitoring is detailed and accurate, thanks to improved DAC technology that provides plenty of headroom and dynamic range.
Build & Design
The iD4 MkII stands out with its all-metal construction, sleek matte-black finish, and intuitive front-panel layout. The large volume knob doubles as a virtual scroll wheel (“iD” knob) for controlling your DAW or plugins — a unique workflow boost.
Dual headphone outputs (¼-inch and ⅛-inch) make it easy for two users to monitor simultaneously, while dedicated monitor mix controls provide latency-free tracking.
Compact and bus-powered, it’s travel-friendly without sacrificing durability.
