  • Notes

  • The Pioneer SR-202 is a solid-state reverberation amplifier introduced in 19690. This unique device was designed to enhance the naturalness of audio playback by adding reverb effects to various sources such as recorded voices, radio broadcasts, records, and tapes.

    Key Features

    • Double Scatter System: Unlike single scatter systems, the SR-202 employs a double scatter system that merges and blends two channels to create a complex composite sound.
    • Time Delay Circuits: Two time delay circuits eliminate peaks and dips in reverberation, resulting in stable sound with depth and brilliance.
    • Flexible Integration: The SR-202 can be coupled with existing amplifiers (with tape monitor jacks) in various configurations, allowing users to apply reverb effects to speakers, recorded sounds, or both.
    • Multiple Connection Options: It supports various connection setups, including the ability to control two tape recorders simultaneously for recording with or without reverb.
