(400-0987)                 Installation               Faxback Doc. # 46537



Your RadioShack High-Power In-Wall Stereo Volume Control lets you adjust
the volume on a pair of speakers that are located in a room separate from
the stereo, so you can control the sound on the spot.

CAUTION:  This volume control is limited to a maximum of 50 watts RMS/100
          watts maximum, per channel.

Mounting The Volume Control

The volume control is designed to be mounted in a standard electrical wall
Box.  Select a location that is:

   Within reach of the speaker wires

   Easy to reach for using the volume control

WARNING:  You must mount the volume control in a standard electrical box.
          Do not mount it directly on a wall.

IMPORTANT:  Overtightening the screws might damage the wall plate.

            Some electrical wall boxes are a non-standard size.  Be sure
            that you measure the wall box before you mount the volume 
            control.

1.  Run wiring from the sources through the electrical box.

2.  Connect the wiring to the volume control (see "Connections" below).

3.  Insert the two supplied short screws into the holes on the volume
    control's wall plate.

4.  Place the volume control in the electrical box and secure it with the
    screws.

Connections

Note:  Your local RadioShack store sells the necessary speaker wire to
       make the connections.

CAUTION:  Letting stray wire ends touch an adjacent terminal, the mounting
          brackets or screws, or the metal sides of the electrical box
          could cause a short circuit or damage a speaker.

1.  Strip off 1/2 inch (12.7 mm) of insulation from each end of the
    amplifier/receiver and speaker wires.

    CAUTION:  Be sure to follow the correct polarity (+ to + and - to -)
              when making connections. Improper connections might cause
              poor stereo reproduction and reduce the bass response.

2.  Insert the amplifier/receiver's + and - left speaker output wires into
    the volume control's INPUT L+ (left positive) and L- (left negative)
    terminals, then tighten the screws.

3.  Insert the amplifier/receiver's + and - right speaker output wires
    into the volume control's INPUT R+ (right positive) and R- (right
    negative) terminals, then tighten the screws.

4.  Insert the left speaker's + and - wire ends into the volume control's
    OUTPUT L+ and L- terminals, then tighten the screws.

5.  Insert the right speaker's + and - wire ends into the volume control's
    OUTPUT R- and R+ terminals, then tighten the screws.
