CX Discs : Better, Worse & the Same as a normal record - A Forgotten Format

CBS envisioned all records made after 1982 utilising their CX encoding system, but if you've bought any music on vinyl since the mid 80s, you won't see a CX logo on the sleeve...so what went wrong. Watch this video to find out.

Answers to regularly asked questions
Q) What kind of monitor is that?
A) Here's my video about it:
Q) if you could have played the audio samples shown, what do they sound like
A) It’s very hard to spot the differences. It’s just that the very quietest moments (which are fleeting and only last for a fraction of a second in these pop songs) are a little bit louder. You can hear the section highlighted on the waveform in the link below -and you'll see why I didn't include it in the video as it does a very good job of proving very little. The sample is played in the following order CX Disc, CX=ON, Normal Record, CX Disc, CX=OFF
Q) What is that Subscriber counter thing in the background?
A) Here's my video about it:
Other Questions:
Q) Did CED & LaserDisc players have built in CX decoders
A) Yes they did..except for some of the very earliest models.
Q) Could you take pictures of both sides of that circuit so I can try and reverse engineer it and make my own CX decoder.
A) Nope - there's no need - Instead, follow the guide in this issue of Popular Electronics if you want to build your own
