Our take on the Niles MVC100R

by Barry Montgomery
Niles

These auto-muting in-wall volume controls from Niles let you fine-tune the way your multi-room audio system powers up throughout your home. Each volume control offers its own auto-muting circuit, so you can independently set each pair of speakers in your system to come on automatically when you turn on your system, or remain silent until manually activated via the in-wall control. Auto-muting is especially handy for outdoor speaker installations — you'll never accidentally surprise your friends or neighbors with unexpected sound when you fire up your system, regardless of where you've left the volume setting.

Note: You'll need to wire the in-wall control to a 12-volt power source, such as the Niles MVC HUB4.

These volume controls also offer impedance magnification, which lets you safely connect as many as 8 pairs of speakers to a typical receiver or amplifier. You won't have to install 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.

Details:

  • requires 12-volt power connections, such as provided by the Niles MVC HUB4
  • selectable auto-muting circuit
  • 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)
  • power handling: 100 watts per channel
  • 12-step control, 54dB maximum attenuation
  • pop-free switching between all steps
  • accommodates up to 14 gauge wire
  • removable knob and Decora-style insert for quick and easy color changes
  • fits most 18-cubic-inch single-gang junction boxes at least 2-9/16" deep
  • dimensions: 2-13/16"W x 4-9/16"H (includes faceplate); depth behind plate: 2-9/16"
  • warranty: 10 years

Features

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: 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 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.

Installation Considerations

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.

10lbs of stuff in a 5lb junction box

Written By mswope, Katy, TX on Thursday, May 19, 2005
Crutchfield Customer Review (What's this?)
 
It works. It took some doing - it takes up the whole single-gang junction box, so the wiring had to go somewhere - I took care of that with a hammer and chisel and knocked the back out of the box.

Setting levels takes some getting used to, but once they're set on the receiver (hopefully you have a 2-zone receiver), you shouldn't need to adjust them except on the control themselves. Muting works, but
****you need 12Vdc at the control****
to operate it. Yeah, I know it says this in the specs, but it needs to be writ LARGE and with bold blinking colored text. This means that you probably need an extra pair of wires running to the control, too... Think about it...

All that aside, they work as advertised and are nice to have...
