Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
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.
