Sansui RA 900 Stereo Reverberation Amplifier
In the seventies and eighties some reverb amps were developed by Sansui: RA-500, RA-700, RA-900 and RA-990.
The addition of reverberation (or echo effects) to stereo sources can make all musical reproduction seem much closer to the authentic realism of the original performance - concert hall realism, disco realism, much more.
This efficient unit has a special circuit with which to mix a tape, FM or record sound with another source - say, a microphone or guitar sound. It also accepts two stereo tape decks, cassette or open-reel, and permits dubbing in either direction.
Designed for instant 19-inch rack mounting is this one of the first hifi gadgets and it looks nice, or?
