Connecting your components
1. Use the supplied quick-connect terminal block to connect the "B" source to the Opti-Source
card inputs.
2. Connect the "A" source to the AmPlus™ 100 "A" source inputs on the amplifier rear panel at
J1.
3. Connect the Zone 2 Remote Volume control to the remote volume terminal on the Opti-
Source card.
Setting System Controls
Set the System Controls as follows:
1. If your sound system has been designed for mono sound and you are sending both "A" and
"B" sources to one zone, place the input mode switch to the MONO position.
2. If "A" and "B" sources are being sent to one zone, but stereo is desired, place the Input
Mode switch to the 2-CH position.
3. If the AmPlus 100 amplifier is being used to power two zones, but only one zone needs A/B
switching, place the Input Mode switch to the 2-CH position.
4. If you are switching four zones (two per source) place the Input Mode switch in the 2-CH
position.
5. Before setting gain levels, turn the Remote Volume control's pot fully counter-clockwise. If
you are using the source card in the manual mode, place the A/B switch to the "A" position.
Setting Gain Levels
If the music compressor is "ON"
1. Begin with the "A" source. Play a music selection that represents the loudest music that will
be regularly played. Adjust the source "A" level controls on the rear of the AmPlus amplifier
until the music compressor LED glows green. If the LED changes to red, the level is too high;
lower the gain control until the LED stays green.
