PRE-CONSTRUCTION
The EA-MR-COMM-RVC-25 ts easily into the majority of single-gang boxes and
rings available today. If local building code allows, use of a ring provides for the
easiest installation as the full depth of the wall is accessible. Some building codes
allow low voltage devices such as volume controls to be enclosed in the same
electrical boxes as 110 volt devices. Episode® does not recommend this type of
installation, as interference may be introduced to the audio signal. For the same
reason, take care not to install volume controls next to high-wattage light dimmers.
WIRING
• The EA-MR-COMM-RVC-25 can accommodate 12 to 22-gauge speaker wire.
The longer the run, the thicker the wire should be.
• All in-wall and in-ceiling wire installations are subject to local code re ratings.
Never use lamp or zip cord for an installation where the wire will be in a wall
or ceiling. Always use multi-strand copper speaker wire for these installations.
UV-protected wire should be used for outdoor installations.
• Check your local building and re rating codes for low-voltage device installation
and wiring requirements before you begin your installation.
• In existing construction installations, check for obstructions such as any pipes,
conduit or wiring before cutting into drywall.
INSTALLATION
The removable connector allows for easy termination of speaker wire to
the volume control.
1. Strip back 1/4˝ of insulation from each wire that is to be connected to
the volume control. Twist the exposed conductors tightly so that there
are no stray strands.
2. Connect the wires going to each speaker to the connector labeled OUT.
Make sure to maintain the proper polarity.
3. Check that the amplier or receiver being used is turned o and then
connect the wire coming from the amplier to the connector labeled IN.
4. Insert the wires in the appropriate openings as shown in Fig. 1, paying close
attention to proper color code and polarity. Then, using a small Phillips or
standard blade screwdriver, tighten the four screws in the connector block
to secure the wires.
5. Visually inspect each of your connections to ensure that there are no stray
strands that might short, and that there is not an excessive amount of exposed
wire outside of the connector. Also, ensure that the connector is tightened down
on bare wire and not insulation. Install the connectors back on to the volume
control circuit board. Make sure the connectors are in the correct place
on the volume control.
REVERSING THE AMPLIFIER AND SPEAKER CONNECTORS WILL LIKELY CAUSE
DAMAGE TO THE AMPLIFIER, VOLUME CONTROL AND THE SPEAKERS, AND
IS NOT COVERED UNDER WARRANTY.
6. Install the volume control in the box or ring using the two longer screws provided.
Be careful not to force the volume control into the ring or box, as this will cause
the connectors to become loose or may result in wires being forced out of the
connectors.
7. Place Decora plate over volume control. Insert and tighten short color-matched
screws until the cover is tight and ush with the wall.
DO NOT CONNECT THE WIRES FROM THE AMPLIFIER TO THE VOLUME CONTROL
UNTIL YOU HAVE CHECKED THE FOLLOWING:
• Measure the resistance between the + and – of each pair of wires that is to be
connected to the amplier’s speakers outputs using an Ohm Meter. Under no
circumstances should this value be below 3.5 Ohms. A reading of less than 3.5
Ohms may mean that the wiring input and output connectors on the volume
control have been reversed. An open reading likely indicates a polarity reversal.
• Conrm that the amplier is powered down before connecting any volume
control wires to it.
