Pioneer designed this amazing unit to add spring reverb to a home stereo. It uses RCA connectors and aesthetically matches Pioneer home stereo components of the era. There are some dings and dents, markings, etc. All are very visible in the pictures. Normal wear and tear. One side has a scratch that's significant enough to notice. It's small. The back left corner also has a bit of a ding. Please be sure to look at all pictures. We plugged it in and everything lights up. All knobs turn with ease. 

Item measures 12-3/4"L x 9-1/2"D x 5-1/2" height. It weighs approximately 12 lbs. 


SR-202W effectively adds good-sounding reverb to a signal. In addition to a brushed aluminum faceplate and Walnut wood paneling, it provides a large and distinctive display to illustrate the time setting with a retro look.


The SR-202W replaced the SR-101, its tube predecessor. The SR- 202W provides a nice stereo reverb effect at a very affordable price


The reverberation amplifier is one of Pioneer's unique products.


Unlike ordinary high fidelity systems that use single scatter systems, the SR-202 employs a double scatter system involving the merging and blending of two channels in a complex composite sound.


The direct signals from the pick-up that have been fed through the preamplifier, and the reverberation signals, which are comprised of the signals of the opposite channels to which reverberation effects have been added, are merged and blended to result in a composite sound that includes echoes and reflected sounds.


Two time delay circuits eliminate any peaks or dips in reverberation so what you hear is absolutely stable and has tremendous depth and brilliance.


The SR-202 reverberation amplifier can be used to increase the naturalness of your own recorded voice, radio broadcasts, records or tapes.


It can be coupled with your own system's amplifier (with tape monitor jacks) in various ways, to provide reverberation effects to the speakers only, or to just the recorded sounds, or both together.


You can even control two tape recorders at the same time by switch operation for simultaneous recording, recording with reverberation, playback etc.


In fact you can connect the SR-202 in practically any way you like for the effects you want. The system can be converted back to normal operation any time with the flip of just one switch.
