  • The eight channels are arranged in pairs to provide amplification for four stereo zones.
  • The R850MC 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.
  • The R850MC 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 two high-output toroidal transformers.
  • Each output channel incorporates robust protection circuitry for safety and reliability under extreme circumstances
