High Power Stereo Speaker Control Center
Terminal Buttons
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).
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.
• Connect the most frequently used speakers to the
terminals marked

• Connect the speakers you use least often to the ter-
minals marked

Cautions: To avoid damaging your speakers or receiver/
amplifier:
• 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.
• Do not connect more than one pair of speakers to
each set of terminals.

• 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.
