The Cebek PM-1 is a 47K Ohm HIGH input impedance microphone preamp module. It provides a line level output signal and has an on-board potentiometer for gain adjustment. It is designed for use with low and high impedance microphones.
It comes from our family of mono audio preamp modules that are based around the popular TL071 Low-Noise JFET-Input General-Purpose Operational Amplifier IC and operate on 6-18V dc power supply.
Other modules in the range are:
Cebek PM-2: Microphone Preamp Module (560 Ohm Low Impedance). Designed for use with low and high impedance microphones
Cebek PM-4: General Purpose Preamp Module (10K Ohm Impedance). Designed to suit a wide range of applications
