To test RCA and 1/4" TS cables, plug each end of the cable into the proper jack
and wiggle the cable around at different points on the cable. Watch the 1 and 2
LEDs, if either LED is off, or goes on and off - the cable is bad.
The testing procedure for 1/4" TRS (stereo) and XLR cables is identical to the
above, except watch the 1, 2 and 3 LEDs.
Adapter type cables, such as 1/4" to XLR cables, may also be tested by plugging
each end into it's proper jack on either side of the line. Test as indicated above.
To test a MIDI cable, plug each end of the cable into the MIDI jacks and test as
described above. Watch the 1 and 2 LEDs, if either LED is off, or goes on and off
- the cable is bad.
NOTE: WHEN TESTING A 1/4" MONO TO RCA CABLE, CONNECT THE 1/4"
PLUG TO THE LEFT 1/4" JACK AND THE RCA TO THE RIGHT RCA JA CK.
DUE TO A PAR TICULAR CIRCUIT CONSIDERATION, TESTING VICE VERSA
(WITH THE 1/4" ON THE RIGHT AND THE RCA ON THE LEFT) WILL BE
INACCURATE.
TEST INDICATORS

1 LED = SHORTED WIRES
2 LEDS = RCA, MIDI OR MONO CORD GOOD , OR CR OSSED WIRES
