Yes, I owned a copy of the long/short promo at one time and both sides were treated to that godawful Haeco-CSG system -- where the commercial 45 & the commercial 12' were NOT Haeco-CSG processed.

Andrew, I just read up on the Haeco-CSG processing that you mention. Given that it was developed by A&M, I think that is exactly what I was hearing on the Carpenters' "Calling Occupants..." promo 45. It sounded like things were out of phase. Totally sucks!

Can anyone confirm this one?


Exhibit "A"

Exhibit "B"


May I ask a technical question here? I noticed that Exhibit A showed a 45-rpm disc that was "stereo-compatible". The opposite of this was when records used to be labeled as stereo - but playable on mono equipment.

Now how can one stereo groove be any less susceptible to damage than another, when both are played with a mono cart? If the mono cart is made to not respond to vertical movements on a stereo groove, would it not damage both of them equally?

Just when anyone has time, I'd love to hear the answer.
Cheers,

To Jody:

The "Stereo-Compatible" designation on 'Exhibit A' meant in this case that the tape had been ran through the Haeco-CSG System. CSG stands for "compatible stereo generator' (NOT "compatible stereo groove").

The Haeco-CSG System pretty much shifted the left/right channels 90 degrees out-of-phase so that when the record was played on a mono system or broadcast the center-channel information wouldn't be 3db louder in respect to the hard left & right information.

Problem was, it sounded terrible in stereo with no distinct center-channel.

The old 'stereo--playable on mono equipment' designation really didn't mean much (other than the record company was trying to phase out mono records).

Using today's digital editing tools, is there a way to undo that phase shift, or did it involve "re-mixing" the channels after the phase had been tampered with?

The 45 version sounds great on Rhino's Just Can't Get Enough Vol. 2 (1994), with differently EQ'd digital clones on Time-Life's Sounds Of The Seventies Vol. 39 Pop Nuggets Late '70s (1995) and Time-Life's 2-CD Modern Rock Vol. 6 The '70s (1999).

The 45 version on Sire's Just Say Yesterday (1992) has a tape azimuth alignment error between the L and R channels, which screws up the soundstage and sounds terrible when summed to mono. Avoid.

The LP version is pretty hard to find on CD. I only have it on one disc, swaitek's 50-CD The A List Disc 6 (1994), where it's taken from vinyl.

The Ben Liebrand Remix was a UK hit in 1989 - that's what's on Priority's Mega-Hits Dance Classics Vol. 10 (1991).
