The DBX CT-3 Cable Tester is an advanced cable testing unit allowing you to evaluate a large variety of cables with ease. Featuring a vast number of audio connectors on it as well as RJ45 and RJ11, the CT-3 can be used for testing pre-installed and long cables.
The DBX CT-3 is a rugged, 2-piece cable tester designed to quickly diagnose faults in a wide range of cables, from audio and network to DMX and banana connectors. Its key features include a unique 2-piece chassis for testing installed cables from sender and receiver ends, illuminated LED indicators and a rotary dial for simple operation, and a built-in tone generator for troubleshooting entire signal chains. The CT-3 is an essential tool for live sound technicians, studio engineers, and installers to verify cable integrity, find shorts, and ensure reliable connections in diverse professional audio and data environments.
The CT-3's primary use case is fast, reliable cable diagnostics, which saves time and prevents malfunctions in critical setups. Live sound engineers can use it to test speaker, XLR, and DMX cables between the stage and mixing desk, while studio professionals can check mic, TRS, and RCA connections to prevent issues during recordings. For installers, its ability to separate into sender and receiver units is invaluable for testing long or pre-installed cable runs in walls or conduits, allowing for quick identification of faulty wiring without having to disconnect the entire length. Additionally, the built-in tone generator allows users to test signal paths from the cable, confirming both continuity and proper function all the way to the other end.

Nice device - Not what I needed
Jan 3rd 2013Super high-quality test device, heavy and built like a tank. Would be useful for toning out cable runs etc, but cannot detect an intermittently bad mic or guitar cable, which is what I was looking for.
