CONGRATULATIONS ON SELECTING AN EPISODE™ VOLUME CONTROL.
Episode is one of the most highly-regarded brands of electronics
and speakers available today. We appreciate your business and
we stand committed to providing our customers with the highest
degree of quality and service in the industry.
The Episode EVC-100R and EVC-100S are 12-step stereo volume
controls that feature selectable impedance-match settings of 1X,
2X, 4X, and 8X. This allows you to connect multiple speakers to
an amplier without overloading the amplier.
PRE-CONSTRUCTION
Both the EVC-100R and the EVC-100S t easily into the majority
of 18 cubic inch 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 EVC-100R and the EVC-100S can accommodate 14 to 22gauge speaker wire. The longer your 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 your installations. UV protected wire should be
used for outdoor installations.
• Check your local building and re rating codes for low voltage device
installation & 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.
SETTING THE IMPEDANCE SWITCH
A single switch on the EVC-100R and the EVC-100S changes the
impedance setting of the volume control. Three factors determine
the correct setting:
1) The minimum impedance rating of the amplier being used.
2) The number of speakers being connected to the amplier channel.
3) The impedance of the speakers being connected to the amplifier channel.
Carefully determine the system impedance. Once that is done, the switch
settings for the volume control are easy to make.
Two simple equations will determine the system impedance:
1) Impedance Rating of Speakers divided by the number of speakers
connected to channel = System Impedance
Is/N=It
2) Ampliers Minimum Impedance Rating / by System Impedance
= Impedance Match Switch Setting
Im/It=X.
