Niles Audio WMVC100 Details
The WMVC 100 is a weatherproof muting stereo volume control with a programmable automatic muting feature. It connects between a Niles MVC HUB4 Distribution Hub and your speakers.
The WMVC 100 is a wall-mounted muting volume control designed specifically for environmental use. It adjusts the volume of remotely located speakers to which it is connected by attenuating the amplifier signal. The mute button opens and closes a relay to turn those speakers on or off.
To assure minimal dissipation of internal power with virtually no power wasted as heat, the WMVC 100 uses autoformers instead of L-pads as the volume-controlling element.
The WMVC 100 is an impedance-magnifying (IM) volume control. Unlike other brands, it has additional autoformer windings that magnify the impedance of connected speakers, while allowing all 12 steps to adjust the volume of the sound. Switched on the PC board select these windings.
