three. Testing
Finally. Take a �test drive� with some favorite music or movies.
1. With the receiver/amplifier still turned off, confirm that its volume control is turned all the way down. Next, center the balance control. If the receiver/amplifier has an A/B speaker switch, set it to correspond to the speaker terminals connected to the SCS110 system. 2. Now, turn on your receiver/ amplifier and select a music source such as a CD player, cassette deck or FM tuner. 3. Turn up the volume control slowly until you hear sound from the speakers. 4. Rotate the balance control all the way to the left. Sound should come only from the left speaker. If the sound comes from the right speaker with the balance control to the left, the speaker wires have been reversed during hook-up. Turn the receiver/ amplifier �off� and switch both sets of speaker wires. Dolby Pro Logic*-equipped devices (AV Receivers, Surround Sound processors or decoders, TVs or other sources) include a �test tone� you can use to balance the volume of all the speakers in a surround sound system. Refer to the instructions accompanying your component for selecting the test tone mode and using it to balance speaker levels in your home theater.
