Introduction

The SVL-6 is a combination speaker selector and volume con-
troller. It allows you to connect up to six pairs of speakers to
your stereo receiver or amplifier and adjust the volume of
each pair independently. Additionally, you can choose to lis-
ten to any one pair, any combination of pairs, or all pairs at
once. You don't have to worry about overloading your ampli-
fier. The SVL-6 has a protection circuit that keeps your ampli-
fier running safely, even with all six pairs of speakers playing
at the same time.

A perfect application for the SVL-6 is individually controlling
speaker "ON/OFF" and volume adjustment for six pairs of
speakers: one pair in the room with the main stereo system
and five additional pairs in remote locations. The SVL-6
adjusts the volume of the speakers connected to it by attenu-
ating the amplifier signal. Niles volume controls use auto-
formers instead of L-pads for the volume controlling element.
This assures minimal internal power dissipation with virtually
no power wasted as heat.
