Features

In-Wall Volume Control: The Niles VCS100K (FG01652) is a high power 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. It is designed for indoor use only.

• 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

Selectable Impedance Magnifying Circuit: A universal impedance magnifying circuit enables the VCS100K 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.

• The VCS100K can be used with 4-, 6-, or 8-ohm speaker systems.
• Isolated left and right-channel grounds ensure safety with any amplifier.

12-Step Control with Autoformers: 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.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 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 Options: The VCS100K installs in-wall in a standard single-gang junction box (J-box). The VCS100K fits into most 18 cubic inch single-gang junction boxes. The mounting depth of the VCS100K 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.

• You can install the VCS100K 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.
• To install the VCS100K 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.
• The volume control measures 1.532" (w) x 4.066" (h) x 3.421" (d). The cover plate measures 2.935" (w) x 4.711" (h) x 0.255" (d). The cutout of the cover plate measures 1.314" (w) x 2.6375" (h).
