Essential Info

The Niles Audio WMVC100 Weatherproof Muting Volume Control with Selectable Impedance Magnification is an in-wall weatherproof stereo volume control designed specifically for environmental use with a programmable automatic muting feature. It connects between a Niles Audio MVC HUB4 Distribution Hub (sold separately) and your speakers. you can adjust the volume of remotely located speakers to which they are connected by attenuating the amplifier signal. The mute button opens and closes a relay to turn those speakers on or off.

The WMVC100 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. 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.

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 an IM 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.

Additional Features and Benefits
  • Designed for environmental wall-mount installation
  • A rubber gasket fits behind the faceplate during installation to seal out moisture
  • Allows you to mute speakers with the simple push of a button at the volume control, without having to turn the volume-adjustment knob
  • The automatic muting feature is programmable allowing certain locations (such as the sauna and porch) to remain muted when system activation turns on other locations (such as the kitchen and pool area)
  • An impedance-magnifying switch on the front of the volume control sets the impedance of connected speakers. You can magnify the speakers' impedance by a factor of two, four, or eight.
  • Unlike other impedance-matching volume-control products, Niles Audio IM volume controls maintain a 12-position adjustment regardless of how much impedance magnification you use, with total attenuation >48dB
  • Pop-free switching between all steps

  • Mounting depth of only 2-9/16". Fits into standard 18-cubic-inch one-gang junction boxes
  • Standard faceplate and knob included
  • Isolated left- and right-channel grounds ensure safety with any amplifier
  • May be used with 4-, 6-, or 8-ohm speaker systems
