USB audio interface Audient iD4 MKII 24-bit 96kHz, 1-in/2-out, desktop recording interface

The Audient iD4 MKII is a compact USB audio interface designed for desktop recording with 24-bit/96kHz conversion. It offers a single mic/line input with a high-quality preamplifier, a dedicated instrument input, and a stereo pair of outputs for monitoring. The interface delivers low-latency performance and simple tactile control suitable for singer-songwriters, podcasters and small project studios who need reliable, clear recording and playback on a computer-based setup.

Advantages

The unit combines studio-grade mic preamp performance with a straightforward desktop layout, giving precise gain control and a clear signal path. Its 24-bit/96kHz converters maintain audio fidelity for recording and mixing, while the instrument input accepts passive and active pickups without additional adapters. Physical monitoring controls and direct monitoring reduce latency during tracking, and the compact enclosure fits easily into small workspaces.

How to use

Connect the Audient iD4 MKII to a computer via USB and install any required drivers or software if prompted. Plug a microphone or line-level source into the XLR/line input and adjust the preamp gain for a clean signal, or insert an electric guitar or bass into the instrument input and set the input gain accordingly. Use the direct monitoring switch and monitor volume controls to set zero-latency monitoring while tracking. Route the outputs to studio monitors or headphones for playback and adjust the headphone level for private monitoring. Control recording and playback from your DAW while using the interface as the audio I/O device.

Usage recommendations

For best results, set input gain so the level meters in your DAW rarely peak and maintain headroom of a few dB. Use balanced monitor cables to reduce noise when connecting to studio monitors, and enable direct monitoring during recording to avoid latency. Regularly check for driver or firmware updates to ensure compatibility with your operating system and DAW.
