The Peavey OPM is a powered output / balanced line ouput module for the MMA, WMA, UMA, and IPA series of Architectural Acoustics mixer / amplifiers. The OPM consists of a 5W power amplifier and a balanced line amplifier, both driven from either the internal mix signal or external line-level source.
The two signal sources are internally pre-selectable with a slide switch included with the module. Two separate screwdriver adjustable controls are included that adjust the powered and line level outputs. Euro connectors, and an unbalanced RCA line input round out the features of the OPM module. The electronic balancing affords a good Common Mode Rejection Ratio (CMRR) at a low cost for short to medium cable runs.
