Product Research

Installation Considerations


Overview: The WVC100K is a waterproof stereo speaker volume control that connects between the speaker-level output of an amplifier, speaker selector, or a Niles distribution hub and a pair of speakers. Premium-quality parts and construction ensure high-fidelity sound with flat frequency response and 100 watts continuous power handling.

Four Colors: The WVC100K installs in-wall in an outside location in a standard single-gang junction box (J-box). The package includes a wall plate and knob in each of four colors - white, almond, bone, and black.

Selectable Impedance Magnifying Circuit: A universal impedance magnifying circuit enables the WVC100K to act as both stereo and an impedance magnifying volume control. You can magnify the speakers' impedance by a factor of two, four, or eight, allowing you to connect up to eight pair of speakers to a single amplifier or receiver. A sliding switch on the front on the volume control lets you set the impedance factor to 1x, 2x, 4x, or 8x.

12-Step Control: The rotary design gives 12-step control, and a total of more than 48dB maximum attenuation. The high-quality construction assures you get pop-free switching between all steps.

Autoformers: Precision autoformers provide superior sonic performance, exceeding the audio quality of non-impedance magnifying volume controls.

Removable Screwless Speaker Connectors: Two piece, screwless speaker connectors make installation quick and secure. Each connector can accept up to 16-gauge wire.

Isolated Grounds: Isolated left and right-channel grounds ensure safety with any amplifier.

Impedance Compatibility: The WVC100K can be used with 4-, 6-, or 8-ohm speaker systems.

Installation Considerations

Outdoor Wall Mount Application: The WVC100K volume control is designed for environmental wall-mount installation. It comes with a waterproof rubber gasket to protect the volume control's internal circuits from moisture.

Speaker Wire: The WVC100K will accept stranded copper wire up to 16-gauge. Larger (lower gauge) wire is not recommended, as it will not fit into the connectors. Solid-core, aluminum, or "Romex" wire is not recommended. Most states require in-wall speaker wire to have a specific "CL" fire rating.

Required Tools: To install the WVC100K, you will need a Phillips screwdriver and wire stripper.



  • Audio Power Handling: 100 watts/channel RMS; 200 watts/channel peak music power
  • Frequency Response: 20 to 20,000 Hz (+/-1.5 dB)
  • Impedance: compatible with 4-, 6-, and 8-ohm speaker systems



  • Volume Control: W=1.541", H=4.067", D=3.43"
  • Wall Plate: W=2.99", H=4.765", D=0.311" (Cutout Diameter: 0.693")

I have a Niles Outdoor volume control already and the white plastic yellowed horribly very quickly. It clearly wasn't outdoor grade plastic like the siding. Has anyone had problems with this product yellowing?

I have 3 outdoor rotating knob style under a covered patio. My turn knobs have yellowed slightly but the plates themselves have not.
[ KIMBERLY  Jul 07, 2020 ]
Mine is in direct sun and hasn't turned color at all. Maybe contact Niles. It's rated for outdoors, shouldn't deteriorate so quick
[ james  Jul 07, 2020 ]
I have had mine mounted on outdoor, non-screened but covered porch for little over a year and have not had any discoloration.
[ Brannon  Jul 07, 2020 ]
I can not understand how to connect speaker wire to vollume control manual not helpful. I have removed the clip where does wire go?

Will it shut the speakers off even if the receiver is still on?
[ Monee  Aug 27, 2017 ]

Hi Monee, Yes. This is wired between the receiver/amplifier and the speaker. It shuts down my Polk Atrium outdoor patio speakers and my Yamaha ceiling speakers in the shower and bath just fine. It will not turn off self-powered speakers though.
[ Michael  Aug 28, 2017 ]
It will control the volume to zero, but it doesn't power off your amp.
[ FRANCISCO J  Aug 28, 2017 ]
Yes - will control volume from zero (off) to max.
[ James  Aug 28, 2017 ]
Yes it will
[ JOE  Aug 28, 2017 ]
How many outdoor speakers can this control? Can this manage 2 pair of Polk Atrium 4 speakers?
[ Michael  Aug 22, 2016 ]
2 answers
This can handle one pair of speakers not two.
[ Jim  Aug 24, 2016 ]
One pair only
[ DAVID  Aug 23, 2016 ]
