A CD that is Multichannel

I just bought a CD, Angel CDQ 7243 5 55199 2 4 (good grief what a number) that is the 1994 Broadway cast recording of "Carousel". As it was playing I noticed on the cover the "Dolby Surround" logo. I went over to the prepro, which was set on 2 channel analog input, selected digital input and Dolby, and Bingo! Multichannel. Not bad either.

I didn't know that any CDs were multichannel. Does this conform to the Redbook specs? Are there other discs like this?

Dolby Surround is 2-channel, with some rear-hall ambient information mixed in the 2 front channels, reverse-phased. The DS decoder senses the out-of-phase info and sends it to the mono surround channel usually played by 2 channels of amps and speakers. This is a 'matrix' system, same as the QS and SQ 4-channel systems of the '70s.

I had an RCA CD of Mancini movie music that was mixed in Dolby Surround, and at least some of the RCA Classic Film Score Series CDs were mixed in Dolby Surround.

El, are you using some sort of signal processing? CDs really have just TWO channels. Maybe your processor is making more than what's there?
