The R275HC is rated at 75 watts per channel into 8
ohms and 100 watts into 4 ohms. With the
Stereo/Bridge Mono switch in the Bridge Mono position,
both amplifier channels are combined for a higher pow-
ered mono output. In Bridge mode the R275HC is rated
at 200 watts of power into a single 8-ohm load. All this
power is backed by a high output toroidal transformer.
Each amplifier output channel incorporates robust pro-
tection circuitry for safety and reliability under extreme
circumstances.
