The Russound R1250MC is a 12-channel power amplifier ideal for use as the main amplifier in home theater and distributed audio systems.

Performance Features

The 12 channels are arranged in pairs to provide amplification for six stereo zones. The R1250MC provides an array of useful features such as autosensing line inputs, bridged mono operation, independent zone triggering, bus inputs and multiple speaker outputs per zone to meet a wide variety of applications and configurations.

Design Features

The R1250MC is rated at 50 watts per channel into 8 ohms and 80 watts per channel into 4 ohms. With a zone’s mode switch set in the Bridge Mono position, both channels in the zone are combined for a mono output of 140 watts into an 8-ohm load. All this power is supplied by three high-output toroidal transformers. Each amplifier output channel incorporates robust protection circuitry for safety and reliability under extreme circumstances.
