Wrapped in a rugged aluminum chassis and powered directly via USB-C, it is an ideal solution for producers, musicians, and creators who need studio-grade sound in a portable form.

Pristine Audio Conversion with Burr-Brown Converters

At the core of iD4 MKII are premium Burr-Brown converters, delivering high-resolution 24-bit audio with exceptional dynamic range and low distortion. This transparent conversion accurately preserves subtle detail, transient response, and tonal nuance in every recording. Paired with Audient’s console mic preamp offering up to 58 dB of gain, the iD4 MKII provides professional-quality capture straight out of the box.

Simple Plug-and-Play USB-C Connectivity

The updated USB-C connection ensures seamless plug-and-play operation on both macOS and Windows systems. The interface is fully bus powered, eliminating the need for an external power supply and keeping your setup clean and portable. With a single USB-C cable, iD4 MKII delivers reliable power, fast data transfer, and consistent performance whether you are working at home or on the road.

Compact Design Built for Real-World Use

Housed in a durable all-metal aluminum enclosure, iD4 MKII is built to handle everyday use and frequent travel. Its compact footprint fits easily on crowded desktops or into backpacks and gig bags. A large central control knob provides intuitive level control, while multi-color LED metering gives instant visual feedback of your input levels. Despite its small size, the iD4 MKII feels solid, professional, and ready for serious work.

Smart Monitoring and Creative Control

iD4 MKII includes features that enhance both recording and mixing workflows. ScrollControl turns the main volume knob into a virtual scroll wheel, allowing hands-on control of compatible software parameters. Dedicated speaker on and off switching, monitor mix and pan controls, and true 48V phantom power over USB ensure accurate monitoring and reliable microphone performance. Dual headphone outputs provide flexibility for solo creators or collaborative sessions.
