WARNING - THIS IS A JAPANESE MODEL OPERATES ON 100V ONLY!!! FOR USE IN THE UK A 240v to 100v (NOT 120/110v) down-step transformer is needed.While quadraphonic encoders have not seen many changes in their designs over the years, the decoders have evolved rapidly since the first designs were introduced back in the early 70s. The Sansui QSD-1 quadraphonic decoder is the only decoder that utilizes an active crossover - processing the Low, Mid, and High Frequencies on 3 separate modules - resulting in superb, best analog QS separation. Hence, the Sansui QSD-1 is considered the best QS decoder and was an integral part of many recording and broadcasting studios back in the 70s.I was behind the first Quadraphonic audiophile listening event at Cafe Oto London in January 2020. Cosmic Quadraphonic at The Southbank Centre on July 22nd and WOH22. I always use the QSD1 in all my QUAD::raphopnic events.Photos exhibiting a few of my own QSD-1. 2nd photo provided by a happy customer, it showing the performance and great separation of his newly purchased QSD-1 through a visualiser.
