PIONEER RG-2

The Pioneer RG-2 is an audio processor designed in the 1970s by Pioneer. It is specifically a dynamic compressor/decompressor (or "Dynamic Range Expander"). This device is used to improve the sound quality of recordings, by improving their dynamic range, that is to say the difference between the quietest and loudest sounds.

When playing back recordings (often from cassettes or vinyls), the RG-2 allows you to restore some of the reduced sound dynamics during the original recording, giving a feeling of greater richness and depth of sound. It also allows you to adjust the degree of dynamic expenditure according to your preferences via a potentiometer.

Often used with hi-fi amplifiers to listen to vinyls, cassettes or soundtracks with a more lively sound, it is also used to reduce the 'flat' effect of audio formats with a limited dynamic range.
