Introduction
The SVL-4 is a combination speaker selector and volume
controller. It allows you to connect four pairs of speakers to
your stereo receiver or amplifier and adjust the volume of
each pair independently. Additionally, you can choose to
listen to any one pair, any combination of pairs, or all pairs at
once. You don't have to worry about overloading your
amplifier. The SVL-4 has a protection circuit that keeps your
amplifier running safely, even with all four pairs of speakers
playing at the same time.
A perfect application for the SVL-4 is individually controlling
speaker "ON/OFF" and volume adjustment for four pairs of
speakers: one pair in the room with the main stereo system
and three additional pairs in remote locations.
The SVL-4 adjusts the volume of the speakers connected to it
by attenuating the amplifier signal. Niles volume controls use
autoformers instead of L-pads for the volume controlling ele-
ment. This assures minimal internal power dissipation with virtu-
ally no power wasted as heat.
