Features
Overview: The Niles EVC-100 is
a wall-mount, infrared-sensing, push button-style, stereo loudspeaker electronic
volume control with muting and impedance magnifying all in a single component.
It is designed to provide volume control of a loudspeaker pair (including muting
and un-muting functions) and IR control of your AV system from a remote
location.
Universal Impedance-Magnifying Design: The
universal impedance magnifying design enables the EVC-100 to act as both a
stereo and an impedance-magnifying volume control. The EVC-100 has a loudspeaker
impedance magnification factor of one, two or four times.
Speaker Compatibility: The EVC-100 can be
used with 4, 6 or 8 ohm speaker systems.
Autoformers: Precision autoformers provide
superior sonic performance, exceeding the audio quality of non-impedance
magnifying volume controls by virtually allowing no internal power to be wasted
as heat.
12-Position Control: The volume
control features a 12-position adjustment range regardless of how much impedance
magnification is used.
Default Volume:
The EVC-100's Default Volume feature guards against high-volume
un-mutes. The default volume is set to 6 from the factory but can be changed to
any of the 12 volume positions.
Sleep Mode: The EVC-100 can be
automatically set to mute itself after an elapsed period of time of 10 or 30
minutes or 1 or 2 hours. During sleep time the Power Sense LED will blink every
second to indicate the mode is active.
Status Detection Circuits: The
EVC-100 is equipped with status detection circuits that monitor the absence of
voltage for automatic mute control when a zone or system is first turned on.
Isolated Grounding: The volume
control features isolated left and right channel grounds to ensure safety with
any amplifier you are using.
UL Rated: The volume control is
UL-rated so it complies with all local building codes.
Override Function: The override
function allows page/doorbell signals to override the music at a preset level,
even with the volume turned all they way down in a mute state.
Remote Control: The EVC-100
comes supplied with an IR wireless remote control that provides volume control
and mute functions.
Decorative Wall-plate: The unit
comes supplied with a white or black decorative wall plate that is held in place by 2
screws.
Speaker Selector Systems: The
EVC-100 can be used with a central control speaker selector unit. It is
recommended you use a selector box that has a defeatable protection circuit to
avoid volume loss such as the Niles HPS4, HPS6, SS-4 or SS-6.
IR Repeater System Compatibility:
The EVC-100 is compatible with all Niles infrared systems. It can be used
along with, or as an alternative to the Nile TS100, WS100, MS100, MS200, and
CS100 IR sensors.
Installation
Considerations
Junction Boxes: The mounting depth of the
EVC-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 EVC-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. 16-guage speaker wire can be
used for runs less than 80 feet while 14-guage wire is recommended for wire runs
over 80 feet.
Power/Control Wire: The EVC-100
requires a CAT-5 data cable to receive 12 Vdc Power and Override, Status, IR In,
and IR Out control signals at its RJ45 connector. For best results, use a
high-quality, shielded data cable for this connection.
Mounting Location: You can install the
EVC-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.
Magnification Settings:
Magnification settings will vary depending on your Amplifier's minimum ohm load
and the number of speakers in your setup.
- EVC-100 used with an Amplifier
that has a minimum speaker load of 4 ohms.
