– Identify the white wire that goes to the #1 position on COMM106. Connect to the tip
terminal on the Front Panel Auxiliary Input jack, J105. Solder.
– Identify the white wire that goes to the #3 position on COMM106. Connect to the ring
terminal on the Front Panel Auxiliary Input jack, J105. Solder.
– Prepare an 18-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 4-

on switch SW101. Solder.
– Identify the white wire from position #3 on CONN107. Connect to the #3 (left) position
on switch SW101. Solder.
– Prepare a 17-inch long audio cable. Attach connector pins to each of the two wires (the
