RG2

About the RG2

The Pioneer RG-2 is a stereo dynamic processor manufactured between 1980 and 1982. It features a 5-stage dynamic expansion selector that compensates for dynamic range compression commonly applied in modern recordings, such as reduction of transient peaks, overall compression of loud levels, and upward manipulation of soft levels. By correcting these distortions, the RG-2 increases audio contrast and restores the original live program's dynamic feel, enhancing richness and depth of sound. It is typically used with hi-fi amplifiers to improve playback of vinyl, cassette, or other limited dynamic range audio formats. The unit has no internal amplifier and relies on the main amplifier for power. Users are advised to keep expansion settings below 13dB to avoid pumping effects, with recommended settings around 7dB for classical music and 10dB for rock or jazz.
