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 WMVC100E is a
waterproof stereo volume control that connects between the MVC HUB4 speaker hub output and a pair
of speakers. Premium-quality parts and construction ensure high-fidelity sound
with flat frequency response and 100 watts continuous power
PVC Enclosure: The volume
control mounts in the supplied weatherproof PVC enclosure, which features a
rubber gasket that seals out the moisture. The PVC enclosure has a paintable
12-Position Volume: The 12-step control
knob offers pop-free volume adjustment with maximum attenuation greater than 48
To assure minimal dissipation of internal power with virtually no power wasted
as heat, autoformers are used instead of L-pads as the volume-controlling
Impedance Magnifying Circuit: The WMVC100E
has additional autoformer windings that magnify the impedance of connected
speakers, still allowing all 12 steps of volume adjustment. You can magnify the
speakers' impedance by a factor of one, two, four, or eight, allowing you to
connect up to eight pair of speakers to a single amplifier or receiver (assuming
8Ω speakers and an amplifier with a minimum impedance rating of 8Ω).
Muting Circuit: A relay is opened and
sound is totally muted at the press of the button below the volume knob. The
programmable automatic muting circuit keeps music from playing in specific
locations when you turn on your audio/video system. Note:
Because the muting circuit requires 12 volts DC to operate, the unit must be connected to power and ground with item 190MVCHUB4
(or some other speaker level distribution system with 12 volt output).
Speaker Connectors: Removable, 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.
Impedance Compatibility: The WMVC100E
be used with 4Ω, 6Ω, and 8Ω speaker systems.
Mounting: The WMVC100E
surface-mounts on a wall or mounts directly on a 1" PVC conduit.
Speaker Wire: The speaker connectors will accept
stranded copper wire up to 14-gauge. Niles recommends 16-gauge for wire runs
under 80 feet and 14-gauge for 80 feet or more. Larger 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.
Required Tools: To install the WMVC100E,
you will need a Phillips head screwdriver and wire stripper.
