About the Niles VCS100R
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!
- 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)

More details on the Niles VCS100R
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.
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.
Audio Power Handling: 100 watts/channel RMS; 200 watts/channel peak music power
Frequency Response: 20 to 20,000 Hz (+/-2 dB)
Impedance: compatible with 4-, 6-, and 8-ohm speaker systems
