Connect one speaker at a time to the left and right channels of your receiver/amplifier …

Slide the switch on the back of the speaker all the way over to the ‘Mono’ position.

Connect the Right red (+) amplifier terminal to the Mono red (+) speaker terminal and the Right black (-) amplifier terminal to the Mono black (-) speaker terminal.

Repeat entire procedure for other speaker, using the Mono Input.

If a speaker is not working correctly, refer to the “Troubleshooting Guide” at the bottom of this page.

Using a Volume Control

Using a Paradigm® VC-150 volume control (sold separately) eliminates the need for additional amplifiers, and compensates for the impedance drop that results when connecting multiple speakers. You can also use the Paradigm® VC-150 on individual speakers or groups of speakers, to control volume at various points on your property—further promoting even and spacious coverage. Follow the directions included with the VC-150 Volume Control.

When used outdoors, the Paradigm® VC-150 must be enclosed in a weather- proof box designed for use with electrical switches (see dealer).
