The Cebek PM-4 is a 10K Ohm input impedance general purpose preamp module suitable for a wide range of applications. It provides a line level output signal and has an on-board potentiometer for gain adjustment.
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-1: Microphone Preamp Module (47K Ohm HIGH Impedance). Designed for use with low and high impedance microphones
Cebek PM-2: Microphone Preamp Module (560 Ohm Low Impedance). Designed for use with low and high impedance microphones
