The CBT-500 Audio Cable Tester by Hosa takes the guesswork out of the frustrating and time-consuming troubleshooting process. It tests all the most common audio cables including XLR, Phone, Phono, speakON, DIN, Ethernet, BNC, and USB – confirming the working or non-working status of each. But that’s not all, the CBT-500 also includes two removable leads to verify continuity of additional connectors and comes equipped with a 9-volt battery to get you up and running right out of the box.

This battery-powered Hosa cable tester diagnoses signal failure in your cables with any combination of XLR, 1/4″, RCA, and speakON connectors. It even accommodates DIN, ethernet, 75 Ohm BNC and USB Type A to Type B cables. Along with the cable tester, you will receive removable test probes for testing bare wire and connector combinations not already found on the unit.
