SV L- 6 INSTALLATION & OPERA TION GUIDE N I LES ® MODEL SV L - 6 SPEAKER SEL ECTION /VOLUME CONTROL SYSTEM SV L- 6.
Introduction The SVL-6 is a combination speaker selector and volume con- troller. It allows you to connect up to six pairs of speakers to your stereo receiver or amplifier and adjust the volume of each pair independently. Additionally, you can choose to lis- ten to any one pair, any combination of pairs, or all pairs at once.
Features and Benefits The SVL-6 offers a number of improvements over other speaker selector/volume controllers: ● The SVL-6 uses 1 2 position volume controls which are superior to 1 0 position designs. You get a broader range of adjustment — there are 1 0 steps of attenuation instead of 8.
● Printed circuit board design assures high reliability. ● Two-piece removable connectors greatly simplify installa- tion and hookup. All wiring can be attached directly to the connectors before installing them in the SVL-6.
Installation Considerations SVL-6 Power Handling The SVL-6 is designed for use with a receiver or amplifier hav- ing a maximum power output of 1 00 watts per channel at 8 ohms. Damage caused by the use of a higher-power receiver or amplifier will void the warranty.
The SVL-6 includes impedance correction circuitry which protects your receiver or amplifier from low impedance loads. The circuitry assures that your receiver or amplifier will see a safe operating load, even when all six speaker pairs are playing at the same time.

Installation 1. Select a convenient location for the SVL-6. 2. Run all the necessary wiring to the SVL-6. Label the wires for future reference. See (Figure 2) .
3. Make the connections to the SVL-6. The amplifier/speaker connectors on the SVL-6 are removable. If you wish, you may remove the SVL-6's connectors to facilitate installation [see (Figure 3) ]. Strip 3/8" of insulation from the end of each wire.
Operation There are two ways to use the SVL-6. You may play and adjust the volume of one pair of speakers at a time, or play multiple pairs simultaneously. If you intend to play more than one pair of speakers at the same time, you will need to become familiar with the oper- ation of the SVL-6's PROTECTION button.

You can turn off the speakers by turning the appropri- ate volume control on the SVL-6 fully counter-clockwise or by pressing the ON/OFF button.
3. Set the SVL-6 volume controls which correspond to the speaker pairs you wish to play to maximum. 4. Locate the appropriate ON/OFF buttons on the SVL-6. Set them to the ON position. 5. Turn on the amplifier or receiver and select as source, such as the tuner or CD player.
Constant Protection Switch The SVL-6 is equipped with a manual override for the protec- tion circuit that enables you to defeat the front panel protec- tion switch and maintain constant impedance protection. This will safeguard your amplifier from being overdriven due to accidental or improper use by anyone unfamiliar with the equipment.
