6. CABLE TESTING
The PC80 is designed to be an overall polarity checker of electronic audio systems, not a cable tester.
If a false reading is found in a system and a cable fault is suspected then ideally a cable tester should be
used to trace the fault. The LA Audio 'T-Box' will check a cable and indicate which pin is o/c or which wires
are swapped. However, if you want to check an individual XLR cable and the PC80 is what you have at
hand:
• Set the 'Hot Pin' switch on both units to Pin 2 and select 'LINE' as the input on the Receiver.
• Set the 'Hot Pin' switch on both units to Pin 3.
If the cable is correct the 'Green' LED will flash in both cases, if the cable is reversed it will show nothing,
thus indicating a fault condition.
Note: The Level potentiometer on the Emmiter should be set to approximately 3 o'clock for this test.
