Coleman Audio M3PHMKIII Passive Monitor Controller

The Coleman Audio M3PHMKIII is a 1U passive monitor controller with 4 input source and 3 balanced outputs with Mute switches, Mono and Polarity reverse buttons and a new specificially designed 47-position stepped attenuator.

The Coleman Audio M3PHMKIII is a complete monitoring solution letting you switch between three sets of monitors as well as letting you monitor four different input sources. L/R mute switches let you identify playback issues while the mono switch and phase reversal let you test mono compatibility or phase cancel different signals for exact monitoring.

The Coleman audio replicates all the main functions of the master section of a console and integrates neatly in your studio especially compuster based studios. Using only passive components also ensure the highest sound quality with none of the distortion added by active components.
