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 studio-ready, fitting easily into any engineer's toolkit without sacrificing durability or reliability. This unit belongs on every studio tech's bench—whether maintaining a home recording setup, mobile session rig, or fixed installation.
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 microphone and line interconnects, digital control, and speaker circuits from one device—essential for troubleshooting session problems and verifying cable health before critical recording sessions.
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—ideal for quick studio cable checks between takes.
