WhitakerAudio
power management expansion PWB. Attach quick-disconnect terminals and install on the
Loop1/Loop2
post.
– Find the short #22 slate wire from the BIAS terminal on the right channel PWB. Connect
to the
BiasSense
post on the power management expansion PWB.
Cut a 2-inch long #22 black wire. Attach a quick-disconnect terminal to each end of the wire.
Attach to the Cabinet Interlock Bypass posts.
5.6.14 Feedback Circuit Cabling
Find the shielded audio cable. There are two conductors: the drain (shield) and the white
conductor. In all cases, the white conductor will be the signal-carrying wire. In all cases the drain
wire will be ground.
– Prepare a 26-inch long audio cable. Attach connector pins to each of the two wires on one
end of the audio cable. Insert the connector pins into the socket housing as follows: shield
to position #1 and white to position #2.
– 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
Conn1
connector on the right 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 clamps along the side of the
chassis.
– Attach a connector pin to the white wire in the audio cable from Conn1 on the right
channel PWB. Clip off the shield as it is not used. Insert the pin into the socket housing on
Conn5
on the right channel speaker PWB as follows: white to position #2.
– Insert the 4-pin Molex socket for the right channel feedback connection on the
Conn5
header on the right channel speaker PWB. Use the legend on the PWB as a guide.
– Prepare a 26-inch long audio cable. Attach connector pins to each of the two wires on one
end of the audio cable. Insert the connector pins into the socket housing as follows: shield
to position #1 and white to position #2.
