General

A signal injector/tracer is used to inject or detect a signal at a certain point in audio circuits (amplifiers, wirelesses, tone adjustment circuits, ...) to be repaired, so as to isolate the defective component.

In this way defects can be located very easily.

The signal "tracer" can also be used as a simple monitor or amplifier.
