INTRODUCTION
The Russound R235LS is a 2-channel power amplifier
with automatic local source switching capability.
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 a variety of input/trigger options
for versatility in many different applications.
The R235LS is rated at 35 watts per channel into 8
ohms and 50 watts per channel into 4 ohms. With the
Stereo/Bridge Mono switch in the Bridge Mono position,
both amplifier channels are combined for a higher powered mono output. 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.
Power LED: The LED will illuminate red when the
power is on and the amplifier is in Default/standby
mode and illuminate green when the amplifier is
active.
Power Switch: Turns the amplifier on/off. This
switch does not disconnect the main power feed
from the amplifier; this requires that the power cord
be unplugged from the outlet.
