Your RadioShack High Power Stereo Speaker Control
Center lets you connect up to four separate pairs of
speakers to your stereo receiver/amplifier. The control
center is especially convenient if you have speaker sets
in different rooms and want to turn them on and off inde-
pendently.
The control center lets you use one to four sets of speak-
ers at a time, and is designed to operate with a stereo re-
ceiver/amplifier that has a maximum of 100 watts per
channel, and with speaker systems that have a minimum
impedance of 8 ohms (see “Impedance Chart” on
Page 2).
Press open the AMP terminals on the control center, then
insert your receiver/amplifier’s positive (+) wires into the
positive (red) terminals, and negative (–) wires in the neg-
ative terminals. Then press the tabs to close them.
Notes:
MAKING THE CONNECTIONS
• If your receiver/amplifier has more than one set of
speaker terminals (A and B), connect only one or the
other to the control center.
The control center divides the power from your receiver/
amplifier differently to its speaker terminals. (This is espe-
cially noticeable when you connect only one pair of
speakers. If you connect more than one pair of speakers,
see “Impedance Chart” on Page 2 to select the best ter-
minals to connect.) For the best performance, make the
connections based on how frequently you use each set of
speakers.
• For the best results, we recommend 18-gauge, two
conductor speaker wire (not supplied) for most con-
nections. If you plan to locate the speakers further
than 80 feet from the control center, use a heavier
gauge of wire.
Your local RadioShack store carries a wide selection of
speaker wire and accessories.
• Connect the most frequently used speakers to the
terminals marked SPK A.
OPERATION
• Connect the speakers you use least often to the ter-
minals marked SPK D.
Caution: To avoid damaging your receiver/amplifier, set
its volume to the lowest setting before changing the con-
trol center’s settings.
• Connect any other speakers to the terminals marked
SPK B and C.
Cautions: To avoid damaging your speakers or receiver/
amplifier:
To turn on a pair of speakers connected to the control
center, simply press in the desired button (A, B, C, or D).
For example, to turn on the set of speakers connected to
SPK A, press A.
• Be sure your receiver/amplifier’s power is turned off
before you make the connections.
• Never let the speaker wire’s bare ends touch each
other or the adjacent terminals on the control center.
To turn off a pair of speakers, press the button again so it
is in the “out” position.
• Do not connect more than one pair of speakers to
each set of terminals.
