CABLE DETECTIVE
Cable Tester
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, CON- NECT THE 1/4" PLUG TO THE LEFT 1/4" JACK AND THE RCA TO THE RIGHT RCA JACK. DUE TO A PARTICULAR CIRCUIT CONSIDERATION, TESTING VICE VERSA (WITH THE 1/4" ON THE RIGHT AND THE RCA ON THE LEFT) WILL BE INACCURATE.
TEST INDICATORS
NO LEDS = BAD CORD OR DEAD BATTERY
1 LED = SHORTED WIRES
2 LEDS = RCA, MIDI OR MONO CORD GOOD, OR CROSSED WIRES IN STEREO & XLR CORDS
