Thank you for choosing Kopul.
The Kopul CBT-8 is a professional-quality cable tester that
allows users to test the continuity of a wide variety of cables
with a single device. It quickly identies connectivity and ground
problems in some of the most frequently-used cables, and makes
troubleshooting audio and studio setups fast and effortless.
A six-way selection knob provides easy selection of the pins to
be tested. LED indicators illuminate to show that each pin on the
cable is properly connected. The CBT-8 can test cables with any
combination of Speakon, XLR, RCA, 3-pin and 5-pin DIN, TRS,
and 3.5 mm mini plugs. Two removable leads are included for
testing any kind of wire or cable with jacks that are not included on
this model. They also allow for testing connections when building
or repairing cables.
The CBT-8 is ideal for home, project, and professional studio use.
Constructed with a rugged all-metal case, the CBT-8 is a road-
ready addition to the gig bag of musicians, engineers, and mobile
DJs alike.

Operating the cable tester
Testing cables:
1. Plug the connectors of the cable into the corresponding jacks on either side or the top of the
cable tester.
2. Switch the selection knob to “1.”
3. Turn the knob one click at a time to test each pin on the cable (see table on pages 5-6).
Reading the LED indicators
• Yellow and green LEDs light up: There is good continuity on that pin.
• Yellow, green or both LEDs do not light up: There is a faulty connection or possibly a broken
or damaged wire.
• Ground LED lights up: There is a short circuit in the cable caused by a connection between
the pin and the shell.
Use the tables on pages 5-6 to verify proper pin connections

panel of the cable tester.
2. Touch each lead to the corresponding pin on either end of the cable.
