FlexLink Cable Tester

Description

The FlexLink Cable Tester identifies faults in XLR, TRS, and TS cables in under ten seconds. A cable fault causes more wasted studio and live-sound time than any other single technical failure, because the symptom — silence or hum on one channel — is identical to the symptom of a failed input, a failed output, a phantom power fault, or a software routing error. The FlexLink Cable Tester isolates the cable as the problem in one test, freeing the diagnosis to move to the next candidate.

What the Test Reveals and How to Read It

The tester checks all conductor continuity and screen connections simultaneously using a battery-powered LED matrix. Both ends of the cable connect to the tester at once — there is no need to loop the cable or test each end separately:

– LED matrix displays continuity status for Pin 1 (ground/shield), Pin 2 (hot signal), Pin 3 (cold return) on XLR
– TRS mode checks Tip (signal), Ring (return), and Sleeve (ground) simultaneously
– TS mode checks Tip and Sleeve only — correct for instrument cables and unbalanced RCA adapters
– Red LED indicates a fault: open circuit, short circuit, or crossed wiring
– Green LED indicates correct continuity on all tested conductors

Faults the Tester Identifies

The FlexLink Cable Tester diagnoses the five most common cable failure modes:

– Open circuit — conductor broken inside the jacket, usually near a connector
– Short circuit — two conductors touching, often at a connector solder joint
– Pin 1 lift — shield disconnected, resulting in hum and noise injection
– Reversed polarity — Pins 2 and 3 swapped, causing phase reversal in balanced systems
– Crossed wiring — incorrect wiring at one end, common on DIY-terminated cables

Runs on one 9V battery included. Backed by a two-year warranty.
