                               INDICATIONS 

Any 2 
Conductor 
(Mono) “Y” 
Cables 
(Splitters) 

       
 
      2 

Test in two steps. Plug Common connector into “A” 
side of CT and one of “Y’d” ends into “B” side. LEDs 
indicate Pass/Fail. Unplug first “Y’d” end and plug in 
second “Y’d” end to “B”side. LEDs indicate 
Pass/Fail. Do not use Right(R) RCA jacks for this 
test. 

Any 3 
Conductor 
(Stereo) “Y” 
Cables 
(Splitters) 

 
 
      3 

Test in two steps. Plug Common connector into “A” 
side of CT and one of “Y’d” ends into “B” side. LEDs 
indicate Pass/Fail. Unplug first “Y’d” end and plug in 
second “Y’d” end to “B”side. LEDs indicate 
Pass/Fail. This test is not for cables with RCA jacks. 

Stereo (TRS) 
¼” or 1/8” to 
Stereo (L&R) 
RCA 
adapters. 

       
        
      3 

Plug the TRS into the “A” side and plug the RCA 
connectors into the “B” side L&R RCA jacks 
(observe L&R markings on cable, if provided.) 
Alternately blinking Red and Green LEDs indicate a 
correctly wired cable. (Correct wiring for this cable 
is: T to Tip of RCA (L), R to Tip of RCA (R), S to 
both RCA Shields.) A steady Red or Green LED 
indicates a failure for this cable. If a steady Red 
LED is shown, try reversing the L&R RCA plugs 
(some are unmarked.)  

XLR Mic  

   
       3 

If Green and Red LEDs blink alternately, it indicates 
pins 4 (shell) and 1 are shorted together. This cable 
may work OK, but it is not considered correct 
wiring. 

XLR Mic 

 
       4 

A Green LED indicates the 4

th

 conductor is wired 

correctly (shell to shell). If the Red LED is lit under 
this test, try switching to the 3-conductor position to 
test for a pin 4 to pin 1 short as in the example 
above. 

DIN (MIDI) 

 
 
       5 

If the cable fails on the 5-conductor position, try 
switching to the 3 conductor setting. Some MIDI 
cables are wired this way and may work fine in your 
application. Check with cable manufacturer if in 
doubt. 

6.

 Other Special Cables: Male-to-Male or Female-to-Female XLR 

Cables: Use a known good adapter cable to “change the gender” 
of one of the cable ends by connecting it in series with the cable 
under test. Female TS or TRS connectors: Use a known good 
Male-to-Male cable to “change the gender” to Male by connecting it 
in series with the cable under test.
