The Two-Way Speaker Selector Switch is
designed with non-shorting contacts 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.
 This speaker selector switch is
limited to a maximum of 1 watts/channel,
continuous music power.

You can connect the speaker selector switch
between an ampli#er's speaker output ter-
minals and the speaker input terminals.
To connect speaker wire to a speaker selector
switch terminal, wrap the stripped end of the
wire around the terminal's screw stem (under
the washer).
 When using stranded wires, twist
them so all strands contact only the
appropriate ter- minals. If loose strands touch
nearby ter- minals, the system might not
operate properly.
Use a screwdriver to loosen and tighten the
four $ and eight $7 and $7"
terminal screws.
 Be sure to follow proper polarity (– to
– and + to +) when making connections.
1. Connect the ampli#er's left speaker output
terminals to the $& (left) negative (–) and
positive (+) terminals and tighten its screws.
2. Connect the ampli#er's right speaker output
terminals to the $) (right) negative (–)
and positive (+) terminals and tighten its
screws.
3. Connect the #rst speaker system's left and
right negative (–) and positive (+) terminals to
the corresponding $7) and & terminals
on the speaker selector switch and tighten
its screws.
4. Connect the second speaker system's left

Impedance is a measurement of the load
placed on your receiver / ampli#er by the
speakers. The load placed on your receiver/
ampli#er from the speaker selector switch will
vary depending on how many pairs of
speakers you turn on at one time, and on
which speakers you turn on. The chart below
shows the im- pedance for all possible
combinations of 8-ohm speakers.

, Impedance restriction for total speakers
is 4 ohm. Therefore, you should ensure your
system or ampli#er will accept a 4 ohm load at
the speaker output.
