Technics SA-8500X
A quadraphonic AM/FM receiver from the Technics SA-5xx series, produced during the early 1970s with support for CD-4 discrete four-channel audio.
Overview
The Technics SA-8500X is a CD4 AM/FM two/four channel receiver made by Technics, a brand of Matsushita Electric Industrial Co. It belongs to the SA-5xx series, which was known for solid build quality and advanced features for its time. It plays both stereo and quadraphonic, so discrete four-channel sound is possible with compatible records and decoders. The front panel is busy, with a lot of controls and a bright display. That was typical of high-end receivers in the mid-1970s.
