Audient Console Mic Preamps
Four discrete Class-A microphone preamps derived from Audient's ASP8024-HE console design provide transparent recording with generous gain for a wide range of microphones.

Analogue Intelligence Platform
Combines analogue preamplification and tone-shaping circuits with onboard digital processing, offering precise control over recording levels, sound character and monitoring.

Analogue Tone Suite
Shape recordings before they reach your DAW using HMX for harmonic saturation, LIFT for added brightness, GLOW for combined saturation and sheen, and ORBIT for selectable microphone impedance characteristics.

RoomTune Monitor Correction
Calibrates studio monitors to compensate for room acoustics using onboard DSP. The included RM1 Reference Microphone provides the measurement capabilities required for room calibration.

Hardware-Accelerated DSP Effects
Integrated EQ, compression and reverb allow zero-latency effects processing directly on the interface, without relying on the computer's CPU.

Smartgain Automatic Gain Setting
Automatically adjusts microphone preamp gain to an appropriate recording level, simplifying setup when recording multiple sources.

JFET Instrument Inputs
Two front-panel JFET inputs provide direct connections for electric guitars, bass guitars and other instruments, delivering an analogue amp-style response.

Balanced Hardware Inserts
Two analogue send-and-return paths on channels 1 and 2 allow external compressors, equalizers and other outboard processors to become part of the recording signal chain.

ADAT Digital Expansion
Dual optical input and output connections support up to 16 channels of ADAT expansion, making it possible to integrate additional preamps and digital studio equipment.

High-Resolution Audio Conversion
32-bit conversion and high dynamic range capture detailed recordings while providing accurate playback for critical listening.

Flexible Monitor Control
Dual stereo monitor outputs with dedicated hardware controls allow easy switching and management of connected studio monitoring systems.

Independent Headphone Monitoring
Two independent headphone amplifiers and up to four artist mixes provide flexible cue monitoring for performers and engineers during recording sessions.

Digitally Recallable Analogue Controls
Stepped gain controls and digitally recallable analogue settings provide repeatable adjustments and simplify returning to previous recording sessions.

USB-C Bus-Powered Operation
Delivers full interface functionality using USB-C power without requiring a dedicated AC power adapter under normal operating conditions.

iD Control Software Integration
Access the interface mixer, monitoring profiles and configuration settings through Audient's control software for Mac and Windows.
