Two-Way Speaker Selector Switch

Your RadioShack Two-Way Speaker Selec-

tor Switch is designed with non-shorting con-

tacts to connect two pairs of stereo speaker

systems. The switch lets you select one or

both connected speaker systems, without

overloading the transistor output stages.

Caution: This speaker selector switch is lim-

ited to a maximum of 10 watts/channel, con-

tinuous music power.

SELECTING A MOUNTING LOCA-

TION

Select a location that is:

• within reach of the speaker wires

• convenient for switch operation

• suitable for mounting the selector switch

using the supplied machine screws

MOUNTING

Position the speaker selector switch on the

selected mounting location, then screw the

four supplied machine screws into the selec-

tor's screw holes to secure it in place.

CONNECTIONS

You can connect the speaker selector switch

between an amplifier's speaker output termi-

nals and the speaker input terminals.

Note: Your local RadioShack store sells the

necessary speaker wire.

To connect speaker wire to a speaker selec-

tor switch terminal, wrap the stripped end of

the wire around the terminal's screw stem

(under the washer).

Caution: When using stranded wires, twist

them so all strands contact only the appropri-

ate terminals. If loose strands touch nearby

terminals, the system might not operate

properly.

Use a screwdriver to loosen and tighten the

four 

AMP

 and eight 

SPK A

 and 

SPK B

 termi-

nal screws.

Caution: Be sure to follow proper polarity (–

to – and + to +) when making connections.

1. Connect the amplifier's left speaker out-

put terminals to the 

AMP L 

(left) negative

(–) and positive (+) terminals and tighten

its screws.

2. Connect the amplifier's right speaker

output terminals to the 

AMP R

 (right)

negative (–) and positive (+) terminals

and tighten its screws.

3. Connect the first speaker system's left

and right negative (–) and positive (+)

terminals to the corresponding 

SPK A R

and

 L

 terminals on the speaker selector

switch and tighten its screws.

4. Connect the second speaker system's

left and right negative (–) and positive

(+) terminals to the corresponding 

SPK B

R

 and

 L

 terminals on the speaker selec-

tor switch and tighten its screws.
