                                     CABLE TYPES 

2 

¼” Mono (TS) Guitar / Line, ¼” Speaker, 1/8” Mono (TS) Line, 
Single RCA (use only the L (Mono) jacks on CT), NL2 Speakon 
Cables (and 4 conductor NL4 Speakon connectors wired for 2 
conductor service), and 2 conductor adapter cables that have 
mismatched connectors of the above types. 

3 

Stereo (TRS) ¼”, Stereo (TRS) 1/8”, Most XLR Mic cables, XLR 
to TRS Adapters, Stereo (TRS) ¼” or 1/8” to Stereo (L&R) RCA 
Adapters, and other 3 conductor adapter cables that have 
mismatched connectors of the above types. 

4 

NL4 Speakon Cables, Stereo (L&R) RCA, Some XLR Mic 
Cables (if the #4 shell conductor is used) 

5 

DIN (MIDI) cables (some may be wired to use only 3 conductors 
of the 5 available)

 Indications: As the Selector Switch is rotated from the OFF 

position, the Green LED will blink twice to indicate the CT is ready 
to test. The Red LED will then light momentarily to indicate the 
cable is being tested. If the cable fails the test, the Red LED will 
remain lit. If the cable passes the test, the Red LED will go out and 
the Green LED will light. At this point you may want to check for 
intermittent problems by flexing or wiggling the cable. Be aware 
that cables can become intermittent because of wiring problems or 
failure of the connector contacts. Any change in the LED 
indications, even if only momentary, means that the cable has an 
intermittent problem and cannot be relied upon.

5. 

Advanced Tests: Most of the standard audio cables will test 

either Pass or Fail according to the indications described above. 
However, there are some alternative indications given for Pass and 
Fail for certain cables. The chart below describes some of these 
cables and what indications to expect.
