The Russound P100BT is a 1U rack-mountable dual-source stereo power amplifier with built-in Bluetooth, designed to add a room, a patio or a larger space to any audio system. It is rated at 100 watts per channel into 4 ohms and 60 watts per channel into 8 ohms, and a rear switch bridges the channels for 200 watts into a single 8-ohm load. Its shallow 6.54-inch chassis suits tight racks and shelves. Two RCA line inputs manage source priority on their own: the main input carries the everyday source, such as a streamer, and the interrupting input takes over whenever its source, such as a TV or turntable, plays, returning to the main source a few seconds after it stops. Bluetooth streaming from a phone or tablet is built in, with an external antenna for range; pairing starts with a long press of the front power button. Separate A and B speaker outputs, switched from the front panel and sharing one volume control, let one amplifier cover an indoor pair and an outdoor pair. Volume and balance are on the front, with bass and treble adjustable by +/-12dB on the rear. A line output passes the playing audio, Bluetooth included, to another amplifier. The P100BT can stay on, wake on signal, or follow a 12V trigger, and it draws under half a watt in standby.

Installation Notes
Leave one empty rack space above and below for ventilation. Stereo mode needs 4 ohms minimum per output; bridged mode needs 8 ohms and uses only Speaker A. The line out is unbuffered, so daisy-chain no more than three amplifiers.
Ideal Applications
Adding a room or patio to an existing system, TV or turntable priority over a streaming source, outdoor and large-room zones, and simple single-room systems that need Bluetooth from a phone or tablet.
Compatibility
Accepts line-level sources such as the Russound MBX-PRE streamer, TVs or any RCA line output, plus Bluetooth devices. Russound's application example pairs the P100BT with OutBack 5B65mk2 speakers and IC-620 in-ceiling speakers. Works with impedance-matching volume controls or speaker selectors (sold separately) for more speaker pairs.
