INSTALLATION
Type of Speaker Cable
For most applications, 16 gauge, stranded copper speaker cable is recommended for the ALT-
126R speaker connections. For wiring runs longer than 100 feet, 14 gauge wire is recommended.
Always use cable with a "CL" fi re rating.
NOTE - Never use solid-core, aluminum or Romex® type cable with volume controls.
P-Ring and Electrical Boxes
From the wallplate/faceplate to the back of the ALT-126R, the mounting depth of the volume
control is 2-7/8". It requires a minimum of a standard light switch plaster ring (p-ring) or standard
22 cu. in. (or larger) electrical box.
CAUTION: Do not install the ALT-126R into electrical boxes with 110V devices. Do not locate
speaker wires too close to a light switch or dimmer switch as this may cause a humming or
buzzing sound to be heard through the speakers. If it is necessary to locate the volume control
near electrical devices, install it in a separate metal electrical box, ground the box to the electrical
system ground, and route the speaker wires several feet away from the electrical wiring.
EZB Connecting Blocks
The EZB-8 connecting block a Russound accessories that simplifi es the connection of multiple
volume controls and speaker pairs. The EZB-8 is a neat, compact wiring device for connecting up to
eight volume controls to an amplifi er's outputs.
Wiring Instructions
CAUTION: Many receivers operate at a rating of 8 ohms. On receivers that off er A and B speaker
outputs, both A and B connections share the same amplifi er. It is recommended to wire all speakers
to the A output (using an EZB-8) when using impedance matching UltraMatch™ volume controls.
Do not mix speakers connected via volume controls with speakers connected directly to the amp/
receiver.
