Overview: The MVC 100 is a high
power, muting stereo speaker volume control that connects between a Niles Muting Volume Control Connection Hub (item 190MVCHUB4) and a pair of speakers; the volume control requires 12-volts DC to work properly, so it must be connected to a Muting Volume Control Connection Hub. 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 MVC 100 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.
Programmable Automatic Muting
Circuit: The programmable automatic muting circuit keeps music from playing
in certain locations when you turn on your audio/video system.
Speaker Relay: The built-in
speaker relay lets you turn the music on or off in any individual room at the touch
of a button.
12-Position Control: The
make-before-break switch design delivers 12-step, pop-free control for a wide
range of listening volumes.
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 MVC 100 fits into
most 18 cubic inch single-gang junction boxes.
Impedance Compatibility: The
MVC 100 can be used with 4-, 6-, or 8-ohm speaker systems.
Removable Insert and Knob: The
Decora-style insert and knob on the MVC 100 are removable, allowing you to
substitute a different color insert and knob.
Junction Boxes: The mounting
depth of the MVC 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 MVC 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 MVC 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 MVC 100,
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.
