Hosa CBT-500 — Multi-Connector Audio Cable Tester
CBT-500 Overview
The Hosa CBT-500 is a versatile cable tester designed to diagnose signal failure across a wide range of connector types commonly found in professional audio, broadcast, and live production environments. It supports cables terminated with any combination of XLR, Phone, Phono, and speakON connectors, as well as DIN, Ethernet, 75-ohm BNC, and USB Type A to Type B cables. Removable leads extend its utility to verify continuity on additional connectors and jacks not covered by the fixed ports. The CBT-500 is an essential bench and field tool for audio engineers, system integrators, touring technicians, and installation crews who need reliable, fast cable verification.
Operation is straightforward and self-contained, requiring a single 9-volt battery included in the package, making it ready to use immediately out of the box.
