Travel back to the 1970’s with this spotlight on a Panasonic quadraphonic 8 track player complete with 4 speakers. This is the type of setup for quadraphonic sound. Of course a special quad 8 track tape is needed for that super 4 channel quadraphonic experience.
Quadraphonic sound – the precursor to what is now known as 4.0 surround sound. With four channels and with four speakers at the corners of the listening space sounds are reproduced in whole or separately. Quadraphonic audio was the earliest consumer product in surround sound and thousands of quadraphonic 8 track tapes and recordings were made during the 1970s.
