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).

MAKING THE CONNECTIONS

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 SPK A.

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

•Connect any other speakers to the terminals marked

SPK B and C.

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.

Press open the desired SPK terminals on the control cen- ter. Insert the speakers’ positive (+) wires in the positive (red) terminals, and negative (– ) wires into the negative (black) terminals, according to the respective L (left) and R (right) terminals. Then press the tabs to close them.

Terminals

OpenClose

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:

•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.

•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.

OPERATION

Caution: To avoid damaging your receiver/amplifier, set its volume to the lowest setting before changing the con- trol center’s settings.

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.

To turn off a pair of speakers, press the button again so it is in the “out” position.
