R235LS AMPLIFIER 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.
R235LS AMPLIFIER 1 2 3 4 5 10 1 Line Input: The line audio input is a sensing input that will activate the amplifier when an audio signal from a source is present. Only the Left input is used for bridged mode operation. 2 Gain Controls: Left and Right gain controls independently adjust the sound level for each channel. When in bridged mode only the Left control is used. 3 Delay Time: The delay can be adjusted from about 5 seconds to 5 minutes.
R235LS AMPLIFIER BRIDGED OPERATION When the amplifier is in bridged mode operation, both the left and right channels are combined for a higher powered mono output. For bridged amplifier operation, turn off the power to the amplifier and connect an 8-ohm minimum load to the Speaker B output. Following the Bridge Mode markings in red on the back of the amplifier: Connect the negative lead (-) of the speaker cable to the R+ terminal. Connect the positive lead (+) of the speaker cable to the L+ terminal.
R235LS AMPLIFIER POSSIBLE SYSTEM CONFIGURATION The R235LS can be used as a single-source two-channel zone amplifier, or as a local-source amplifier that automatically switches between a default source (e.g., a whole-house audio distribution system) and a local source (e.g., a television set in the bedroom or a PC in the office).
