CABLE TESTING PICTURES - BEHRINGER CT100 TESTER (© W. JASON WOODROW 2019)Website: http://wjwoodrow.wordpress.com

THIS SHOWS THE RESULTS OF TESTING KNOWN GOOD CABLES WITH THE TESTER. (INCLUDES ONE REVERSE POLARITY PICTURE FOR REFERENCE)

BASIC INFO: THE TESTER PUTS A SIGNAL ON THE “PINS” OF THE CABLE. THE TESTERLIGHTS SHOW WHERE THE PIN FROM THE INPUT MATCHES A PIN ON THE OUTPUT. DIFFERENT CABLES HAVE DIFFERENT RESULTS. IF THE INTERMITTENT LIGHTS ARE LIT AFTER WIGGLING THE CABLE AROUND, THEN THERE IS A BREAK OR SHORT IN THE CABLE.

1. PLUG THE ENDS OF THE CABLE INTO AN INPUT AND AN OUTPUT.2. TURN THE TESTER ON.3. PRESS THE RESET BUTTON TO CLEAR THE INTERMITTENT LIGHTS.4. WIGGLE THE CABLE TO SEE IF ANY INTERMITTENT LIGHTS TURN ON.5. IF THE LIGHTS ARE CORRECT AND NO INTERMITTENT LIGHTS CAME ON, THE CABLE IS GOOD.

THE ABOVE PICS SHOW THREE-PIN CABLES (XLR & 1/4-INCH TRS). PIN 1 INPUT MATCHES PIN 1 ON THE OUTPUT. PIN 2 INPUT MATCHES PIN 2 OUTPUT, ETC.

TRS MEANS “TIP-RING-SLEEVE” (OLD TELEPHONE WORDS), HAS 3 PARTSTS MEANS “TIP-SLEEVE”, HAS 2 PARTS

OTHER SIDE OF THE BOX

-MIDI ONLY TESTS THE 3 MIDDLE PINS -TT “BANTAM” 4.4mm TRS WITH ROUNDED TIP-RCA ONLY HAS TIP AND SHIELD - TS

IF A CABLE ONLY HAS 2 “PINS” THEN ONLY TWO LIGHTS SHOULD LIGHT-UP.

HOWEVER, THE TESTER ONLY HAS ONE PAIR OF HOLES FOR 1/4-INCH CABLES, AND IT IS EXPECTING TRS, NOT TS (EXPECTING 3 PINS, NOT 2 PINS) [SAME FOR 1/8-INCH]. SO THE RESULTS LOOK LIKE THIS FOR A NORMAL TS-TO-TS CABLE:

OCCASIONALLY, A SHOP MAY WIRE A CABLE WITH REVERSE POLARITY. MAYBE ON PURPOSE, BUT USUALLY IT IS A MISTAKE. SOME EQUIPMENT COMES WITH REVERSE PHASESWITCHES (TO FIX THIS), BUT OFTEN DOESN’T AND A USING A REVERSE POLARITY CABLE MAY MAKE THE SOUND TINNY OR ODD. THIS PICTURE SHOWS REVERSE POLARITY (AND NORMAL).
