Overview: The Niles Audio SVC100R is a high power
stereo speaker sliding 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), 54dB maximum attenuation, and 100 watts continuous power
Universal Impedance Magnifying Circuit: A
universal impedance magnifying circuit enables the SVC100R to act as both a
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 pairs of speakers to a single amplifier or receiver.
12-Position Control: The make-before-break
switch design delivers 12-step, pop-free control for a wide range of listening
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 SVC100R fits into most 18-cubic-inch single-gang junction boxes.
Impedance Compatibility: The SVC100R can
be used with 4-, 6-, or 8-ohm speaker systems.
Junction Boxes: The mounting depth of the SVC100R
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 SVC100R 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 SVC100R 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
Required Tools: To install the SVC100R,
you will need the following tools: 1/8" standard slotted screwdriver, 1/4"
standard slotted screwdriver, and wire stripper. Other tools may be required to
prepare the wall and junction box to accept the volume control.
