Pioneer SR-9 Stereo Reverberation Amplifier (Made in Japan)

Pioneer SR-9 Stereo Reverberation Amplifier (Made in Japan)

Enhance your vintage audio system with this iconic 1982-83 Pioneer SR-9 Reverberation Amplifier. A staple of the silver-face separates era, the SR-9 adds spacious, room-filling reverb effects that transform ordinary music playback into a dimensional, lifelike listening experience. This very good conditioned unit has been tested and verified working, delivering smooth, responsive reverb across all modes.

The SR-9 features Pioneer’s signature Time/Depth LED display that visually pulses in sync with the reverb decay, creating both functional feedback and aesthetic appeal. Two distinct reverb modes—Echo (0-3 second adjustable decay) and Duet (creates a layered “chorus” effect)—offer creative sound design flexibility. Multiple operating modes (Reverb On, Reverb On-Record, and Bypass) allow you to process playback, create effect-laden recordings, or switch reverb completely out of the signal path. A dedicated unswitched AC outlet (100W max) on the rear accommodates another component without requiring additional cabling.

The amplifier connects via RCA inputs for Reverb and Playback sources, with corresponding Reverb and Recording outputs on the back panel. Input sensitivity is conservative at 150 mV, ensuring compatibility with a wide range of audio sources from turntables to tape decks. The SR-9’s frequency response spans 5 Hz to 70 kHz with negligible distortion (less than 0.05% THD), and signal-to-noise performance exceeds 90 dB—exceptional specs for analog reverb processing.
