Large format consoles are fewer and farther between these days for a number of reasons however everyone still needs a monitor section. The Coleman Audio M3PH MKII delivers exactly what you need in a monitoring section; the ability to switch from one of four sources to one of three destinations. It includes other useful features such as a mono sum switch to check phase, a phase reverse switch and a headphone output. This unit is passive, so you won't be able to add any additional gain (or noise) to the signal as you monitor.
