dbx CT-2 Cable Tester

The CT-2 is a compact continuity tester for tracking down opens, shorts, and miswired connectors in audio cables before a bad run causes hum, dropouts, or a dead channel on show day. It runs on a single 9-volt battery, not included, and fits in a tool bag alongside the rest of a tech's kit.

At 3.5 x 5.5 x 1.5 inches, it is small enough to carry on every load-in, and it is the same tester engineers reach for when a channel goes quiet mid-show and the cable is the first suspect.
