– Cut two short pieces of small heat-shrink tubing, each about 3/4-inch long. Place the
tubing at each end of the audio cable. Process.
– Insert the Molex socket into the
Conn3
connector on the left channel PWB. Note that the
drain wire goes to the first “GND” position.
– Route the cable to the rear of the chassis using the cable clamp along the side of the
chassis.
– Attach a connector pin to the white wire in the audio cable from Conn3 on the left channel
PWB. Clip off the shield wire as it is not used. Insert the connector pin into the socket
housing as follows: white to position #2.
– Insert the 4-pin Molex socket for the left channel feedback connection in the
Conn1
header on the left channel speaker PWB. Use the legend on the PWB as a guide.
5.5.14 Audio Cabling
In the following steps, 2-pin, 4-pin, and 12-pin Molex connectors will be used. After stripping the
cable, place a short (approximately 3/4-inch long) piece of heat-shrink tubing on each end of the
audio cable. For the end of the cable inserted into the Molex connector, process (apply heat) after
the wires have been inserted into the connector but before the cable is installed in the amplifier.
Hardware for the following steps can be found in the “2/4/12 Terminal Molex Housing and
Terminals” package.
Examine the Molex socket housing. The connector pins insert one way only. As each
connector pin is attached, check for a good crimp. Builders should note that the housing is held
against the PWB-mounted pins by the friction of the connector elements. In order to provide for a
good physical mating, it is recommended that any positions on the header that are not used for
wires be filled with a pin.
Note that two types of shielded audio wire will be used. One is single-conductor shielded
cable and the other is three-conductor shielded cable. Use the single-conductor cable unless
stated.
– Prepare a 4-inch long audio cable. Attach connector pins to each of the two wires (the
white wire and the shield) on one end of the audio cable. Insert the connector pins into a 2-
conductor Molex socket housing as follows: white to position #1 and shield to position #2.
