Features and Benefits

The SVL-2 offers a number of improvements over other
speaker selector/volume controllers:

The SVL-2 uses 12 position volume controls which are
superior to 10 position designs. You get a broader range of
adjustment—there are 10 steps of attenuation instead of 8.
Steps 11-6 attenuate -3 dB per step; steps 5-2 are 6 dB per
step. Step 12 is "full-on" and step 1 is "full-off".

Greater dynamic range—you get 42 dB of total attenua-
tion instead of the usual 20 or 30 dB.

POP-FREE  switching between all steps.

Pre-printed Room Labels are included for easy identification
of speaker ON/OFF buttons.

Isolated right and left channel ground returns make the
SVL-2 compatible with all types of amplifiers.

Self-cleaning, silver-plated switch contacts assure many
years of trouble free use.

Printed circuit board design assures high reliability.
