Audient iD4 MKII — Compact USB-C Audio Interface with Console-Grade Conversion

The Audient iD4 MKII brings the brand's renowned console heritage into a portable desktop format. Inside its all-metal chassis sits the same Audient Console Mic Preamp circuit found in the ASP8024-HE recording console, paired with 32-bit AD/DA converters and a JFET instrument DI. This model is engineered for musicians, podcasters, and producers who want genuine studio conversion and preamp quality without a rack of outboard gear.

What Sets the iD4 MKII Apart

Unlike most interfaces in this tier, the iD4 MKII uses a discrete Class-A console mic preamp circuit lifted directly from Audient's ASP8024-HE desk — not a software emulation. The 32-bit AD/DA converter path delivers 126 dB of dynamic range, while the JFET instrument input mimics a classic valve amplifier's input stage for natural DI character.

Conversion and Preamp Performance

The preamp and converter chain is where interface quality is won or lost.

• Mic Preamps: 1 Audient Console Mic Preamp — discrete Class-A with 58 dB of gain and ultra-low noise
• Sample Rate: 96 kHz / 24-bit with 32-bit AD/DA converters and 126 dB DAC dynamic range
• Phantom Power: +48 V per channel — works even when bus-powered

Inputs, Outputs, and Headphone Power

Connectivity centers on a high-headroom combo input, a dedicated instrument DI, and dual headphone outputs.

• Inputs: 6.3 mm jack + Kombi XLR/Jack — combo mic/line input plus JFET DI
• Outputs: 6.3 mm jack + USB-C — stereo line outs plus computer link
• Headphone Outputs: 6.3 mm jack and 3.5 mm mini jack (dual) — drives headphones up to 600 ohms

Build, Portability, and Workflow Features

The all-metal chassis slips into a backpack while feeling substantial on the desk.

• Dimensions: 133 × 120 × 40.7 mm — fits beside a laptop
• Weight: 0.74 kg — light enough for mobile sessions
• Workflow Tools: Monitor Mix knob, ScrollControl, audio loop-back — zero-latency monitoring plus system-audio routing
