INSTALLATION & OPERATION GUIDE

SPEAKER PLACEMENT

If you desire music over a wide area, it is best to have a larger number of speakers playing at low volume, rather than a few speakers playing at high volume. Keep this in mind when designing your system.
Ideally, you should place the speakers as close to the primary listening area as possible. The perceived volume of the speaker decreases rapidly as it is moved further from the listener.

CONNECTING THE SPEAKER TO YOUR SYSTEM

The 4-pin Euroblock plug allows for speaker wire input as well as speaker wire output to easily daisy chain speakers in 70V applications.
Determine the locations for the speakers and estimate the length of the additional wire you will need for each speaker.
Connect the speaker wires from your amplifier to the ceiling speakers.
IMPORTANT: Be sure not to let any stray “+” and “-” strands touch each other. Touching strands can cause a short circuit that could damage the amplifier.
PLEASE NOTE:
Confirm that you have connected the speaker “+” to the amplifier “+” and the speaker “-” to the amplifier “-”.
Turn your amplifier on and test the system with your favorite music.
