AV14 Charge and IEPE Amplifier

The 1-channel charge amplifier AV 14 has been constructed mainly to monitor acoustic and vibration signals. 

It has a measuring channel for an electret condenser microphone or a piezoelectric accelerometer. 

The switching over from the accelerometer to the microphone comes automatically, when the microphone mini-jack is plugged in at the output socket you get a voltage proportional to the acceleration or sound pressure independent of the amplification of the headphone amplifier. 

So the instrument can be used as a front end for analyzers or similar instruments.
