2400 Audio Imperium White (Used)

The 2400 Audio Imperium White is a premium digitally controlled passive stereo monitor controller designed for professional recording studios, mastering engineers, and critical listening environments where absolute transparency is essential. Handmade in Denmark, the Imperium has earned an outstanding reputation for delivering uncompromised analog signal integrity while offering the convenience and precision of digital control.

This used White edition gives you the opportunity to own one of the most transparent monitor controllers available today at a significantly lower price than a new unit. Built around a completely passive analog signal path, the Imperium introduces virtually no coloration, no additional noise floor, and no headroom limitations—allowing you to hear your monitors exactly as they were intended.

Unlike conventional monitor controllers that rely on active circuitry in the audio path, the Imperium combines an entirely passive balanced signal path with digitally controlled relay switching, resulting in exceptional stereo tracking, repeatable volume settings, and uncompromised sonic performance.

Designed for Engineers Who Demand Transparency

The Imperium was developed with one goal in mind: allowing engineers to hear their mixes without the monitor controller influencing the sound.

• 100% Passive Analog Signal Path – No op-amps, capacitors, converters, or active circuitry in the audio path for maximum transparency.
• Fully Balanced Design – Balanced from input to output for exceptional signal integrity.
• Digitally Controlled Relay Attenuation – Precise level control with perfect channel matching and outstanding stereo imaging.
• Mastering-Grade Performance – Designed for critical listening where every detail matters.

Professional Monitoring Workflow

The Imperium is much more than a volume control—it is a complete monitor management system designed to streamline daily studio work.

• 3 Balanced Inputs – Connect multiple playback sources.
• 3 Balanced Outputs – Switch instantly between different monitor systems.
• Parallel Output – Easily integrate a subwoofer or additional monitoring path.
• Insert Loop – Perfect for room correction processors or external monitoring hardware.
• Mono, Mute & Polarity Functions – Essential monitoring tools for professional production.
• Level Bypass – Direct signal path when required.

Precision Through Digital Control

Although the audio path remains completely passive, every control function is digitally managed to provide exceptional precision and repeatability.

• Ultra-High Resolution Attenuation – Extremely fine level adjustments with perfect channel balance.
• Superior Stereo Tracking – Rock-solid stereo imaging at every listening level.
• Eight Configurable Reference Levels – Instantly recall calibrated monitoring levels for consistent mixing decisions.
• Fully Programmable Operation – Configure the controller to match your personal workflow.

Expandable Workflow

The Imperium platform supports a range of optional workflow enhancements for demanding studio environments.
