You need two pairs of speaker pins 
(available at your local RadioShack store) 
to make the connection. 

Follow these steps to connect the wires to 
each terminal using speaker pins.

1. Separate the conductors for a length 

of about 2 inches on the end of each 
wire. Then strip 

1

/

2

 inch of insulation 

from the ends of each conductor and 
twist the wire ends.

2. Position each wire end between the 

open barrel ends of the speaker pin.

3. Using a pair of pliers, crimp the open 

barrel ends of the speaker pin to hold 
the wire ends in place.

4. Plug the speaker pin into the proper 

terminal on the PRO-SW220P.

Once you have made all connections, 
follow these steps to adjust the PRO-
SW220P’s volume.

1. Rotate 

VOLUME CONTROL

 to 

MIN

.

2. Turn on your amplifier/receiver and 

another component (such as a radio, 
cassette player, CD player, or 
turntable).

3. Begin playing an audio source (such 

as a radio) and adjust the amplifier/
speaker’s overall volume to a 
comfortable level. Rotate VOLUME

 

CONTROL 

on the PRO-SW220P 

clockwise a little at a time, until you 
achieve a pleasing balance of bass 
between the PRO-SW220P and the 
main speakers (and satellite speakers, 
if used). Bass output should not 
overpower the main speakers, but 
should blend across the entire musical 
range.
