Introduction The SVL-2 is a combination speaker selector and volume con- troller. It allows you to connect two pairs of speakers to your stereo receiver or amplifier and adjust the volume of each pair independently. Additionally, you can choose to listen to either pair of speakers, or both pairs simultaneously. You don't have to worry about ov[...]

Features and Benefits The SVL-2 offers a number of improvements over other speaker selector/volume controllers: ● The SVL-2 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. Steps 1 1 - 6 attenuate -3 dB per step; steps 5-2 are 6[...]

● Spring-loaded push terminal connectors accommodate up to 1 4 gauge wire or "pins", making the SVL-2 compatible with most "high-definition" speaker cables. ● 1 00% tested, electronically and acoustically, for frequency response, distortion and power handling. ● Only 8 1/2" wide. Match the width of 1 7" component[...]

Installation Considerations SVL-2 Power Handling The SVL-2 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. Consult your Niles dealer, or receiver/amplifier manufacturer, if you are uncertain [...]

The SVL-2 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 two pairs of 4-ohm speakers are playing at the same time. Type of Speaker Wire For most applications, we recommend you use 1 6 or 1 8 ga[...]

near electrical devices, route the speaker wires several feet away from the electrical wiring. Using the SVL-2 with Tube-Type Amplifiers Virtually all tube amplifiers must have a load connected at all times. If the amplifier to be connected to the SVL-2 is a tube amplifier, be sure to always have at least one pair of speakers switched on at all tim[...]

3. Make the connections to the SVL-2. Strip 3 /8" of insulation from the end of each wire. Tightly twist the end of each wire until there are no frayed ends. Insert each wire into the appropriate hole on the spring- loaded connector terminals. Be certain that proper phasing is observed — connect the positive terminals on the SVL-2 to the pos[...]

Operation The are two ways to use the SVL-2. You may play and adjust the volume of either pair of speakers independently, or both pairs simultaneously. If you intend to play both pairs simultaneously, and either pair is less than 8 ohms, you will need to become familiar with the operation of the SVL-2's PROTECTION button. Playing One Pair of S[...]

Turn on the amplifier or receiver and select as source, such as the tuner or CD player. 6. Slowly turn up the amplifier or receiver volume and set it to a comfortable (not maximum) listening level. Be careful not to overdrive [...]

13 S PEAKER S ELECTION /V OLUME C ONTROL S YSTEM Balancing Speaker Volume The volume control on your receiver or amplifier serves as the "master" volume for all speaker pairs connected. The volume level of the speakers may vary from room to room. This is caused by several factors. Two lesser factors are the size of the speaker and its eff[...]
