SSVC-4.1 Single Input 4-Channel Speaker Selector with Volume Control
P/N 38159
Quick Install Guide
INTRODUCTION
The SSVC-4.1 Speaker Selector is a resistor-based, impedance matching speaker selector
used for connecting up to four pairs of 4-ohm or 8-ohm speakers, while maintaining a safe
impedance load for your amplifier or receiver. Each pair of speakers can be independently
turned on or off using push buttons on the front panel, with no need for worrying about
amplifier loading. Each zone features an independent volume control.
FEATURES
Connect and safely control multiple speaker pairs with a single amplifier
Automatic impedance protection circuitry
100 watts/channel continuous power handling capacity, 200 watts/channel peak
5-ohm minimum amplifier impedance with four 4-ohm speakers selected, 6-ohm
minimum with 8-ohm speakers
Individual zone on/off buttons and volume controls
Heavy-duty screw-type connectors supporting 12-18 AWG speaker wire
Isolated left/right circuit grounds provide safe connection for amplifiers with
floating grounds or bridged configurations
Accurate, noise-free switching

INSTALLATION
1. Refer to the manuals for your amplifier and speakers to determine the correct wire
gauge to use with the speaker selector.
2. Lay out all wire runs from each speaker location and your amplifier to the selector.
3. Remove the connector blocks from the selector and connect
them to the wires, as shown in the image to the right.
Carefully inspect the connections for any stray wire strands.
4. Insert the connector blocks back into the selector.
5. Connect the other ends of each zone wires to the speakers and the input wires
amplifier. If your amplifier has A and B outputs, use the A output.
SETTING THE VOLUME CONTROLS
Perform the following steps to configure the volume controls to avoid distortion.
1. Set the amplifier's volume control to the minimum position.
2. Enable each zone and turn each volume control on the selector to the maximum
position.
3. While playing audio material, slowly increase the volume on the amplifier until the
best maximum volume with no distortion is achieved.
4. Turn down the volume of each zone until it is at a comfortable listening level. By
attenuating a previously determined maximum volume level, maximum volume can
be used without fear of causing distortion.
