High Power Stereo Speaker Control Center
(400-0137)                 Connections                Faxback Doc. # 18975

Your Radio Shack High Power Stereo Speaker Control Center lets you connect
up to four different 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 independently.

The control center lets you use from one to four sets of speakers at a
time, and is designed to operate with a stereo receiver/amplifier that has
100 watts per channel or less of power and with speaker systems that have
an impedance of 8 ohms or more (see "Impedance Chart," Faxback Doc.
#18689).

MAKING THE CONNECTIONS

The control center divides the power from your receiver/amplifier
differently to its speaker terminals.  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 terminals 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 center, then insert the
speakers' positive (+) wires in the positive (red) terminals, and negative
(-) wires into the negative (black) terminals.  Then press the  tabs to
close them.

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 negative 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 connections.  Or, if you plan to locate
     the speakers further than 80 feet from the control center, use a 
     heavier gauge of wire.

Your local Radio Shack store carries a wide selection of speaker wire and
accessories.
