The Trinnov D-Mon 4: Much More Than Just Another Monitoring Controller

Monitor control could look very simple to many, but when it comes to managing all the various situations that mixing and mastering engineers have to face day after day, they need as much power and flexibility as possible.

The Trinnov D-Mon® Series is specifically designed to combine power, fast-and-easy usage and flexibility.


  • Both Analog and Digital professional inputs and outputs, providing the most pristine sound quality
  • Facilities to connect the processor via Ethernet and/or MIDI and host almost any protocol to communicate with a large number of other studio equipment
  • A Switching Matrix to route all signals easily and make any patch set in seconds
  • Full Audio Routing Matrix with instant recall and ZERO latency assignment
  • An internal Mixer (from 8 to 16 configurable buses) which can create various sum of stems, main or aux mix, discrete inputs that come in
  • Comprehensive and intuitive web Control Panel (Source & Speaker selection, Level/Mute/Dim, Intercoms, Headphones, etc.) that any connected device can access (Chrome browser recommended)
  • The amazing and world-renown Optimizer® to make the perfect tuning of the loudspeaker sets to the studio acoustics
  • Full Eucon & MIDI compliance (other protocols to come) with the free D-Mon App (MacOS)
  • Optional SmartMeter® software for accurate Time-Code aware Loudness metering and processing features


The Multi-Purpose I/O Connector

The Multi-Purpose Input/Output connector alone proves how much the D-Mon® is in touch with the real world of professionals.

  • MIDI, Headphone output, Talk-Back input are wired just like the famous ICON control surfaces, allowing X-Mon® as a replacement in a complete, seamless way
  • Time-Code is available as a LTC input when you’re running the SmartMeter® to make Loudness metering sessions more effective than ever
  • GPIOs are located there too, so linking to other equipment for synchronizing switches, lights or a simple pedal is immediate and easy

In and Out For Now and the Future

Input & Output configuration depends on models, but all of them cover the needs of recording or mastering studios, post-production rooms and film mixing suites.

  • Up to 16 Digital I/Os (AES), enabling any surround sound engineer, drive not only his main mix but also all feeds (like aux sends, sub-groups or stems) within the best possible resolution and sample rate (up to 96kHz)
  • A switchable 8-channel Digital Insert to hook up an external processing and make instant A/B comparisons or the mastering final cut
  • Up to 8 Analog Inputs able to be assigned as a Cue, the Talk-back or just used as external sources to be converted to digital for whatever reason
  • From 12 to 16 Analog Outputs offer all possibilities to address multiple sets of loudspeakers, headphones and outboard gears, all at the same time
