This is a blank board for building an audio probe. The audio probe is a very useful tool for troubleshooting faults in analog audio circuits of devices, especially arcade PCBs. The probe is powered from power supply of the circuit under test (usually the GROUND and +12V of the sound section) and must be connected to a pair of headphones or a speaker for proper audio output.The gain and volume are adjustable and you just touch the probe tip to the part of the circuit you want to "listen to".
