We all know how frustrating it can be when you know you have a bad cable somewhere in the system, but you're just not sure which cable it is. Out of a hundred. Your audience and the folks who hired you to perform really don't care which cable it is. They expect to see and hear your show, and they expect it now. Avoid this nightmare by testing your cables before it's too late, with the Galaxy Audio JIB/CT 6-in-1 cable tester.
With the JIB/CT, you can test XLR, 1/4" (TS or TRS), RCA, 3.5 mm (1/8" headphone), twist-lock (speakON), and MIDI (DIN) cables just about as quickly as you can plug them in, with easy-to-read PASS/FAIL feedback in the form or a red or green LED. Unlike many cable checkers, the JIB/CT uses a computer-controlled circuit to test your cable 200 times per second, which can identify intermittent shorts, or cables which may work some of the time when "jiggled around just right," but not reliably. Simply plug in both ends of the cable (or adapter cable, or splitter "Y" cable), set the rotary selector to the correct number of conductors, and you're done. Easy as that.
As a performer or sound pro, you have enough to worry about when getting ready for a show. Get a JIB/CT cable tester, invest a few minutes to test your cables periodically, and make sure you have one less thing to worry about.
