Niles Audio SVL-4AB - Manual (Page 3)

Features and Benefits
The SVL-4AB offers a number of improvements over other
speaker selector/volume controllers:
● Amplifier A/B Switching—The SVL-4AB provides amplifier
switching for each pair of speakers. The switches are
“break-before-make“ and simultaneously switch both
grounds and hots. This allows any two amplifiers to safely
and reliably operate simultaneously.
● The SVL-4AB uses 12-position POP-FREE volume controls
which are superior to 10-position designs. You get a
broader range of adjustment —there are 10 steps of atten-
uation 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.
● Pre-printed Room Labels are included for easy identification
of speaker ON/OFF buttons.
● Isolated left and right channel ground returns make the
SVL-4AB compatible with all types of amplifiers.
