S PEAKER S ELECTION /V OLUME C ONTROL S YSTEM Features and Benefits The SVL-2 offers a number of improvements over other speaker selector/volume controllers: l The SVL-2 uses 12 position volume controls which are superior to 10 position designs. You get a broader range of TECH adjustment—there are 10 steps of attenuation instead of 8. SUPPORT Steps 11-6 attenuate -3 dB per step; steps 5-2 are 6 dB per HOTLINE step. Step 12 is "full-on" and step 1 is "full-off". If you have questions regarding l

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 about the power rating of your receiver or amplifier. IMPORTANT: DO NOT US

S PEAKER S ELECTION /V OLUME C ONTROL S YSTEM 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 "TECH TIP" For most applications, we recommend you use 16 or 18 gauge stranded copper speaker wire for the SVL-2 connec- tions. For wiring runs longer than 80 fe

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 times. An alternative is to permanently connect a 150 ohm, 5 watt resistor across the tube amplifier's outp

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 positive terminals on the amplifier and speakers and the negative terminals on the SVL-2 to the negative terminals on

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 efficiency. The largest factor is the physical size of the room. The SVL-2's volume controls allow you to adjust the volume of each speaker pair individually. You can
