The 2400 Audio Imperium 1U Stereo Monitor Controller is a passive digital stereo monitoring system that sounds like nothing you’ve ever heard before. Since Imperium uses no transistors, op-amps or active circuitry, it’s able to provide a plethora of monitoring options without coloring your sound or adding noise floor or headroom limitations. Featuring eight high-quality stereo outputs, Imperium is capable of seamlessly switching between multiple sets of active speakers in your professional mixing or mastering studio.


Instead of a traditional volume control knob, Imperium uses eight pre-defined reference levels, selectable via the front panel buttons, for quickly and easily recalling mix levels at low, medium and high volumes. Mixes and masters are often finalized days, weeks or even months apart—with Imperium, you can recall any session and be certain that you’re getting the exact same listening experience every time. While it may seem strange at first, this unique approach to volume control forces you to take a new approach to monitoring, which leads to more focused and effective mixing.


Imperium packs a ton of unique features into a compact package. Imperium offers on-board flash memory for storing your favorite settings, allowing you to configure the unit to your specific studio setup. Imperium can also be outfitted with an optional Wi-Fi expansion board, allowing you to control settings and upgrade firmware with an iOS or Android app.

An easily accessible Mono button allows you quickly convert stereo mixes to mono. The Cut button is engaged on boot up by default, protecting your precious speakers and priceless ears from unwanted pops. The built-in insert option can be used to connect additional devices, while the Parallel Outputs can be used to send signals to subwoofers or additional speakers. Featuring lighting-fast response time when changing between inputs and outputs, Imperium makes it easier than ever to A/B signals across different systems or speakers.


  • Mono & Cut: Cut is always in at boot up, very nice when wanting to take good care of you precious speakers and, more importantly, your ears
  • Level Bypass: Bypasses Imperium's own built-level system, can be used when having a mixer with control room outputs or a summing amp with its own master level control
  • Phase Left CH: Phase Reversing the left channel on all inputs
  • Insert: Can be used to connect another device into the Imperium instead of the built-in level system, like a talkback solution, level pilot, etc.
  • Parallel Output: Can be used to send a signal to a subwoofer or another pair of speakers along with the selected speakers
  • Lightning fast response when changing inputs or outputs, for instant A/B comparison
  • Stepped attenuation, 8 reference levels
