The SC Series Testers provide rapid, positive testing for multiline speaker cables.

Rotating the central switch applies voltage to the cable conductors one at a time. A SEND LED indicates the pin to which the voltage is being applied, and a RECEIVE LED indicates where it returns.

This system clearly reveals, shorts, opens, and cross-wires, allowing you to test common combinations of speaker cables.
