SH518 Russound Audio Amplifier

Russound Audio Amplifier
View Datasheet

  • Automatic switching of speakers between a local source input and distributed audio system sources
  • Space-saving low profile design permits installation in areas most amplifiers will not fit
  • Bridgeable to create one channel with substantial power output
  • Reliable and robust circuitry designed for stability


Amplifiers are the muscle behind every music system. R235LS puts great pride and effort into building amplifiers that supply years of problem-free service

Performance Features

The R235LS allows a local source (e.g., PC or TV in the bedroom) to automatically override the speakers in that particular zone of a distributed audio system. This can be accomplished with its auto sensing line input or with its trigger input for versatility in many different applications.

Design Features

The R235LS is rated at 35 watts per channel into 8 ohms and 50 watts per channel into 4 ohms. In bridged mode the R235LS is rated at 100 watts of power into a single 8-ohm load. Each amplifier output channel incorporates robust protection circuitry for safety and reliability under extreme circumstances.
