One of the most misunderstood formatting experiments in popular recorded music was Quad.

Of course most of us are familiar with the basic concept of four speakers set up to give the listener the feeling of depth on a recording.  The systems usually required a special receiver, needle, etc. Quad was a blanket term for a bunch of sound designs. CD-4 discreet, UD-4/UMX. Q4, Quad 8, SQ, QS, EV Stereo-4, Dynaquad, Matrix  H & the Hafler circuit were all fairly different takes on the basic concept.  Most had to do with some sort of stereo synthesis or conversion in the audio chain.  WQSR in Sarasota, Florida was the nations longest running Quad radio station, but other stations did dabble in it.  It appeared in 1970 and was on life support by 1975 with only classical titles being produced until 1980...

This is a two parter, today's gallery will be made up of Quad propaganda, the next one will be various releases and such...
