This signal tracer /injector has been designed to inject or detect a specific signal into an audio circuit in need of repair (such as amplifiers, radios, tone controls, ...) so as to detect the fault. In this way problems can be traced more easily. The signal tracer may also be used as a simple monitor or amplifier.
Specifications:

1. signal injector:
   1. 0-2.5Vrms output (adjustable)
   2. output impedance: 1.5Kohm
   3. frequency: ± 1kHz
2. signal tracer:
   1. 3.5mV to 10Vrms sensitivity (adjustable)
   2. gain: 40dB
   3. input impedance: 50Kohm
3. output power: 0.5W / 8ohm
4. power supply: 7-9VAC or 9-12VDC / 150mA
5. dimensions: 60 x 53mm / 2.4 x 2.1"
