Acquiring good sound and listening
   accurately to what is happening -
 arguably the most important things
you ever do in professional audio

The m904b stereo monitor controller uses identical technology and features to those used in the flagship m906 surround controller. It is a perfect control centre for any type of audio production facility - from project studio to world class mastering facility.

The m904b offers a full complement of balanced and unbalanced stereo analogue and digital inputs, the latter featuring the latest generation, reference quality 24/192 DAC technology. Like the m906, all inputs and outputs can be user calibrated for seamless integration into any playback environment with all types of playback equipment.

The m904b comes complete with the m904RCU complete with 25’ cable as standard, but longer cables can be supplied on request.

The critically acclaimed m903 headphone amplifier circuitry is also included. Two headphone jacks are provided on the mainframe and an additional one on the m904RCU. This circuitry provides true audiophile headphone amplification for critical monitoring, mixing and quality control.
