Coleman Audio M3PHMKIII

Designed to be the control room monitor source selector. This unit's control room signal path is completely passive, with a four gang 47 position stepped attenuator, that tracks within ±.05dB. This ensures accurate, and repeatable stereo imaging at any level. Individual mute switches allow speaker isolation and a phase reverse switch helps you check the integrity of the audio path.
A four input source selector and three balanced outputs provide numerous monitoring options in any application.
