Hello herd. How are you folks doing? Grooving on the groovy quad tunes? For a quad format that died out so long ago it is impressive how many folks still enjoy using that now nearly ancient equipment to make a far-out sound-field for audio enjoyment. It is helpful that the matrix quad decoders can create a surround sound by synthesizing a stereo input.
To assist this blog in sharing information about quad I created a Pinterest page showing pictures related to quad. Taken from many different sites the pics can act as a link to sites where the pic is located and that may have other pics and written information you find interesting.

Hello. How is everybody doing out there on planet Earth? Hope that all is well for you and yours. Sure is a crazy world we live in but let’s hope that the good outweighs the bad.
In the meantime we can keep grooving on the wonders of quadraphonics. Music can be enjoyed with no need to dabble in what has become ancient technology but there is fun to be had from the searching for quad hard and software… finding a functioning quad receiver or decoder or a quad vinyl record in great condition for a dollar at the thrift store or whatever you mess around with.
If you are lucky you live in an area where the people of the past got into quad but over time sold their stuff where you can find it at a garage, yard or estate sale or maybe there is a used audio equipment retail store or wherever you find used still-working equipment.
Back around 1993 I was reminded about quad when I saw a “Masterworks” quad receiver in a thrift store with a $9.99 price tag. I plugged it in and used the two available speakers to test for output. All channels worked as did the radio. So… the unit followed me home and a different thrift store had two inexpensive speakers to meet the required four and the used record store led to a demonstration quad album with Black Magic Woman as one of the tunes.
Sure, it was a non-logic SQ decoder but if a placed my rotund head in the proper place the “swirl” as the lead guitar flowed around me head lead me onwards to bigger, better and harder-to-find and more expensive stuff.
Quad hit the marketplace in a big way in 1971. Vanguard Records was one of the early players with their 4-channel reel-to-reel tape. Articles in various magazines from the period of around 1969 to 1970 mention quad sound from reel-to-reel tape. Quad from vinyl records and FM broadcasts is mentioned as being possible in the future.
Quad on tape is usually a discrete-type quad. True discrete quad uses 4 individual audio sources from input to output.
QADRAPHONIC TERMS, LINGO and ASSORTED BITS of STUFF
Decoders using ambiance recovery, such as early Dynacos, worked best on live recordings where the large area of the concert hall allowed natural reverberations and reflected sound waves to be recorded.
Radio-Electronics magazine in its March 1971 edition says the DynaQuad ambiance recovery unit first appeared in the spring of 1970. This product may have led the 70’s ‘quad craze.’
