With these impedance-magnifying stereo volume controls from Niles, you can safely connect as many as 8 pairs of speakers to a typical receiver or amplifier without installing a speaker selector or any other type of protection device.

If your amp's minimum impedance is 8 ohms, you can connect up to 8 pairs of 8-ohm speakers using these volume controls. If your amp's minimum impedance is 4 ohms, you can connect up to 16 pairs of 8 ohms speakers, or 8 pairs of 4 ohm speakers!

Details:

  • connect up to 8 pairs of 8-ohm speakers to a single stereo amplifier (requires 1 volume control per speaker pair)
  • adjustable impedance magnification (2x, 4x, and 8x)
  • power handling: 100 watts per channel
  • 12 step control, 54dB maximum attenuation
  • pop-free switching between all steps
  • accommodates 14-16 gauge wire
  • removable knob and Decora-style insert for quick and easy color changes
  • fits most 18-cubic-inch single-gang junction boxes at least 2-3/4" deep
  • dimensions: 2-3/4"W x 4-1/2"H (includes faceplate); depth behind plate: 2-9/16"
  • warranty: 10 years

Features

Overview: The VCS 100 is a high power stereo speaker volume control that connects between the speaker-level output of an amplifier, speaker selector, or a Niles VCS HUB8 distribution hub and a pair of speakers. Premium-quality parts and construction ensure high-fidelity sound with flat frequency response (+/-1.2 dB) and 100 watts continuous power handling.

Universal Impedance Magnifying Circuit: A universal impedance magnifying circuit enables the VCS 100 to act as 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. Note: Each pair of speakers must have its own volume control and each volume control must be set to the same impedance magnification.

12-Position Control: The make-before-break switch design delivers 12-step, pop-free control for a wide range of listening volumes.

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 14-gauge wire.

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

Mounting: The VCS 100 fits into most 18 cubic inch single-gang junction boxes.

Impedance Compatibility: The VCS 100 can be used with 4-, 6-, or 8-ohm speaker systems.

Removable Insert and Knob: The Decora-style insert and knob on the VCS 100 are removable, allowing you to substitute a different color insert and knob.

Installation Considerations

Junction Boxes: The mounting depth of the VCS 100 is 2-9/16". When installed, the unit extends 2-1/16" behind the sheetrock (assuming 1/2" sheetrock). For installation, you must use a standard 18 cubic inch or larger junction box.

Speaker Wire: The VCS 100 will accept stranded copper wire up to 14-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.

Mounting Location: You can install the VCS 100 in just about any location where in-wall space exists, though it should not be installed into a junction box with 110 volt devices, such as light switches or dimmers. Speaker wire can act as an antenna for electrical noise, and locating speaker wire too close to a light switch or dimmer may cause the speakers to emit a popping or buzzing sound.

Required Tools: To install the VCS 100 you will need a 1/8" standard slotted screwdriver, a 1/4" standard slotted screwdriver, and a wire stripper. Other tools may be required to prepare the wall and junction box to accept the volume control.

Right out of the box the control feels solid and well made. The connectors on the control disconnect from control to make connecting the wires very simple and assuring they are done right. Great Product.

top quality,great appearance

Crutchfield Customer Review (What's this?)

I've been using niles products for over 20 years in commercial applications, (night clubs) and this is the first time i had a reason to use the wall mounted volume control for myself. I wired my bathroom,kitchen and bedroom for sound and i was impressed with how the volume control can be set to adjust for the amount of speakers being used to divide the power load to the amp. it was a little difficult opening up the speaker wire opening thinking I was going to break the plastic legs , but it worked out alright ,hard on the finger nails. after the first one , the next two were a breeze..also bought a speaker selector from niles.

I'm satisified

Crutchfield Customer Review (What's this?)

We have purchased 3 of these units over a couple of years to repalce 15 year old ones that have failed. They're easy to install (take careful notes of wire colors on each side before unhooking the old ones) . They are well made and packaged. A little more costly than Radio Shack, which we bought and threw away. Crutchfield as usual was as usual a relable resource.

Installed these switches in all rooms of the house in new build. Have replaced two already.
On/Off switch sticks...now two additional rooms do not work. Not a good product at all!

Crutchfield Customer Review (What's this?)

Works great and was easy to install. Put a TV in the kitchen that is a slave to the one in the living room with Speakers in the kitchen cieling. Volume control in the kitchen is great for not having to run into living room to turn sound up or down. Product looks great and works great.

Written By Dave, Mechanicsville, MD on Wednesday, September 09, 2009

I have these switches in every room of my home to control ceiling speakers. They work great and allow flexibility for impedences given particular numbers of speakers being driven. I would recommend these switches to anyone wanting control of seperate room speakers.

Use speaker wire that is designed to match building codes and provide rugged shielding.
