INTRODUCTION
The WVC 100 and WVC 100E are weatherproof stereo impedance-magnifying volume
controls that connect between the speaker-level output of an amplifier, speaker selector, or
a Niles VCS HUB8 distribution hub and your speakers.

The WVC 100 is a wall-mounted volume control designed specifically for environmental use.
The WVC 100E is a freestanding volume control mounted in a PVC junction box for use in
environmental where a wall-mounted volume control would be impractical.

Both models adjust the volume of remotely located speakers to which they are connected
by attenuating the amplifier signal. To assure minimal dissipation of internal power with
virtually no power wasted as heat, Niles volume controls use autoformers instead of L-pads as
the volume-controlling element.

The WVC 100 and WVC 100E are impedance-magnifying (IM) volume controls. Unlike other
brands, they have additional autoformer windings that magnify the impedance of connected
speakers, while allowing all 12 steps to adjust the volume of the sound. Switches on the PC
board select these windings.

With the volume control providing impedance protection for your amplifier, you can create
systems with no additional impedance-matching devices between the volume control and
the amplifier.
systems with no additional impedance-matching devices between the volume control and
the amplifier.
In a typical application of IM controls, a system has eight pairs of 8-ohm speakers throughout
the house and in outdoor locations. Connect each pair of speakers to a WVC 100/E volume
control with its switch in the 8x position, eliminating the need for an external impedance-
matching device to protect the amplifier. Even when playing all eight speaker pairs at once, the
amplifier runs at normal operating temperatures.
