Bridging a power amplifier lets the user combine the output of two channels into a single channel. This is useful in powering a single, large speaker with the combined output of the amplifier's two channels, which usually would be directed to two speakers. Crown XLS power amplifiers are renowned for their high performance specs, and feature the capability to operate in bridged mode.
Instructions
1. Turn the amplifier off if the power is on, and set the output switch of the amplifier to "mono".
2. Plug the input from your mixing board or other audio source into the amplifier's Channel 1 input, located on the back of the amp.
3. Remove 1/2 inch of wiring from each lead of the speaker wire you'll be connecting to the amplifier, using wire strippers.
4. Loosen the speaker terminals for the bridged output, by twisting them to the left until a hole appears in the post of the speaker terminals. (The speaker terminals used in bridging the amplifier are the two positive (+) terminals. They'll be colored red, and the panel they're mounted onto will have markings for "Bridged output", "+" and "-".)
5. Slide the speaker wire lead that connects to the speaker's positive terminal to the terminal marked "+", then tighten the terminal onto the speaker wire by turning it to the right.
6. Slide the speaker wire lead that connects to the speaker's negative terminal to the terminal marked "-", then tighten the terminal onto the speaker wire by turning it to the right.
7. Switch on the power to the amplifier.
