A 2 x 130 watt Hi-Fi stereo power amplifier. On the front, a press button for Power and indicators for Power on, Protection and Bridged Mono. On the back, Left and Right input RCA sockets for connection to a preamplifier. In order to use the RB-981 in bridged mode, three “jumper” connectors inside the amplifier must be moved from one set of pins to another. In bridged mode the Left and Right channels are bridged into a into a single mono amplifier and the cable from the preamplifier output is connected to the Left input RCA socket. Four terminals to connect one stereo pair of loudspeakers, or to one loudspeaker in bridged mode where the wires to the loudspeaker are connected to the positive terminals of the left and right channels.
