Procedure:
1. Cut the system cable so that you have one section about 4 feet long and another about 6 feet
long. Retain both pieces. You will use the 6 foot section to build your bass module test cable.
2. Strip back the outer cable plastic covering about 4 inches (100mm)
to gain access to the internal wires.
3. Using a DMM to verify proper wiring, connect the 6 foot section of
the system cable’s wires to the left and right analog audio input jacks,
the digital SPDIF audio jack and the 2.1mm power jack. Use heat
shrink tubing to cover any exposed conductors. Refer to the cable
connector pinout diagram and the console test cable wiring table
below.
Note: Be sure to label the connectors on your test cable so that there
is no chance of using the wrong connector for a test.
Note: You will use the Lifestyle power supply to connect to the
2.1mm power jack on the console test cable. This will allow you to
power up the console without the system bass module.
