Quadraphonic L P played with a 2 chan. cart.

This may sound like a stupid question since I grew up in the 70's when quadraphonic recordings and equipmnet were around, but as I am getting older my memory is really begining to suck. Anyway, I am interested in purchasing a Japanese quadraphonic recording of rare LP and I can not remember if the cartridges were 4 channel or not. Thus; can a stereo cartridge process the information on the LP at least the front two channels?

I still use a Lafayette SQ quadrafonic decoder for the few QS records that I have. I also use it for a way to 'simulate' rear channel information for ambiance effect. There has been no damage done to the original SQ 4-ch recordings by using an 'ordinary' 2-ch phono cartridge - in my case, either the B&O MMC3 or Sumiko Bluepoint special.

Fear not, play away.

Eldarford, I believe the quad LP system, which uses a FM signal, to which you refer, was the JVC CD-4. It was arguably better than the SQ & QS systems, but at least, as you said, it improved the high frequency tracking of cartridges to this day.
