Description
SM Pro Audio CT-2 Multi-Format Cable Connector Test Unit
The CT-2 is a compact, ruggedly built diagnostic tool designed to quickly verify cable integrity across virtually every standard audio connector type. Its metal construction with rubber feet makes it road-ready, fitting easily into any technician's toolkit without sacrificing durability or reliability. This unit belongs in the hands of anyone responsible for maintaining audio systems—whether on stage, in the studio, or in fixed installations.
Connectivity & Testing Capability
The CT-2 simultaneously accommodates eight distinct connector types: 2x XLR, 2x RCA Phono, 2x BNC, 2x MIDI (5-pin DIN), 2x DMX (5-pin), 2x Speakon, and 2x 1/4" TRS/TS. This breadth of support eliminates the need for multiple single-purpose testers, allowing you to diagnose cable faults across analog audio, digital control, and speaker circuits from one device.
Operation & User Feedback
A 6-position rotary selector with individual LEDs guides you through pin-by-pin testing of up to five connections per cable, with an additional internal battery life check position. The front panel houses two banana connections permanently wired as a dedicated continuity tester, complete with both LED and beeper indicators for instant single-pin verification without dial rotation.
