Page 7: Installations And Operation
INSTALLATIONS AND OPERATION 1. Stereo Operation: The PR-150 can be used in the Stereo Mode as two separate 150 watt units, each capable of driving loads down to 4 ohms. Each channel operates independently and has its own input connectors, sensitivity level controls, signal indicator LEDs, automatic limiter, fault protection circuitry, power amp, and speaker outputs. - Page 8 “slave” or “patch” Channel 2 to Channel 1. One method is to connect a short cable from the unused Channel 1 input jack (either XLR or 1/4”) to one of the Channel 2 input jacks. In this way, up to four 8 ohm speakers may be driven at once. The Stereo/Mono Bridge switch must be set to the MONO mode.

- Page 11 5. Mono Bridge Operation: The two internal power amplifiers can be bridged together to form a single, higher-powered amplifier this is especially useful when using the amplifier to power a subwoofer. In the Mono Bridge mode, the amplifier uses the Channel 1 input jacks and Sensitivity control (Channel 2’...
- Page 12 6. Triamping With Two Amplifiers: Two PR-150 can be used to separately power the lows, mids and highs of a three-way system. The Stereo/Mono Bridge switch of the amplifier driving the subwoofer must be set to the MONO mode. The Stereo/Mono Bridge switch of the amplifier driving the midrange and high frequency components must be set to the STEREO mode.
- Page 13 7. Biamping With A Single Amplifier: A PR-150 can be used to separately power the lows and highs of a cabinet with biamp inputs, or a separate low and high frequency cabinet. For Biamp Operation, the Stereo/Mono Bridge switch must be set to the STEREO mode. Use Channel 2 for the high frequencies and Channel 1 for the lows.
