This quality preamplifier module is based on the use of two NE5532 AOPs, allowing a clear and musical reproduction. These are mounted on DIP8 brackets and are therefore easily replaceable to adapt the sound signature of the module.

It also incorporates a volume controller and two tone controls, offering the ability to adjust the bass and treble gain over a range of ±8dB.

For its connectivity, the module provides in input and output a 3.5mm jack and XH2.54mm connectors.
