Audient iD4 MkII – 2-In/2-Out USB-C Interface with Console Mic Pre, JFET DI & Dual Headphone Outs

Make pro recordings from a small desktop. Audient iD4 MkII brings the Audient console mic preamp and class-leading converters to a compact 2-in/2-out interface that’s perfect for singers, guitarists, podcasters and producers. Plug a mic into Input 1, your guitar/bass into the JFET DI, monitor with ultra-low latency using Monitor Mix & Pan, and drive any cans (even up to 600 Ω) via dual headphone outputs. Loopback makes streaming and tutorials easy, ScrollControl turns the main knob into a virtual encoder, and it’s USB bus-powered—including true 48 V phantom—so you can create anywhere, even on iPad (USB-C).

In short: clean, warm preamp tone, punchy conversion, and the right workflow tools to move fast and sound great.

Why It’s Great (plain English)

• Sounds bigger than it looks: the preamp and converters are a genuine step up from typical entry-level units—vocals feel open, DI guitars hit amp sims hard and clean.

• Creator-friendly: loopback for streams/screenshares, two headphone jacks for quick collabs, and a DI that flatters pedals and sims.

• Beginner to pro: easy first interface that still holds its own alongside pricier gear.
