Mono Audio Pre-Amplifier Module Range

A selection of mono audio preamp modules that run from a 6-18V dc power supply (for example our CFE002) and have an onboard potentiometer for gain adjustment.

Model CPM001: Microphone Preamp Module (47K Ohm HIGH Impedance). Designed for use with low and high impendence microphones.

Model CPM002: Microphone Preamp Module (560 Ohm Low Impedance). Designed for use with low and high impendence microphones.

Model CPM004: General Purpose Preamp Module (10K Ohm Impedance). Designed as a general purpose preamp module.

Model CPM007: Guitar Preamp Module (22K Ohm Impedance). Designed for use as a preamp for electric guitars.

These modules can be used with Mono Pre-Amplifier Module with Tone Controls (CPM005).

All modules are supplied fully assembled and tested with instructions so you only need to make the necessary connections.
