    Question Commercial Matrix Quadraphonic Cassettes?

    I am trying to find a definitive answer to the question, were there any commercial matrix encoded quadraphonic cassettes manufactured during the quadraphonic era? I know that Angel records released most, but not all, of its LP's as SQ only. That is, there was no dual inventory for the Angel releases. What about their cassettes? Were the Angel cassettes remixed for two-channel stereo or were the SQ quadraphonic mixes used to make the cassettes?

    I have Angel brochure "The Angel Stereo Quad Catalog" with a list of some of their albums. Cassettes are not mentioned in the brochure. Only LP records are shown. The brochure does offer this: “Packaging identification. All Angel SQ albums are identified by the Angel trademark in the double circle.” Several Angel or Seraphim cassettes I have use the double circle logo on the label, however, nowhere on the cassette sleeve is there anything to suggest that the cassette is SQ quadraphonic encoded.

    Who can shed light on these questions?

    Good question, and I don't know the answer.

    Did Ovation do cassettes?

    On the surface, it might seem like a stereo cassette would be ideal for matrix quad, but in practice it really doesn't work very well. Tape head azimuth can really mess with phase, so recording on one deck and playing back on another would not likely decode properly into four channels ... especially when commercial high-speed tape duplication is used.

    With all due respect,
    I don't think that the difference for a misaligned cassette deck playback head would affect the SQ encoding, unless the angle was ridiculous-and then you'd get crosstalk.

    Mu guess is that ALL of the Angel EMI LPs that are listed as SQ and available in cassette , are SQ encoded..hell, I'll even stick my hand out for the Columbia ones...

    Ahh , cassettes...trip down memorylane

    Look up the difference between alignment and azimuth.

    IIRC, Phillips didn't allow it as the resulting tapes would not be compatible with regular cassette players.

    Oops, you meant matrixed.

    My thinking was that the Angel cassettes would be SQ encoded because their LP discs were single inventory. It is odd, in my opinion, that Angel did not acknowledge SQ encoding on their packaging other than the dual circles around the angel logo. The Columbia cassettes would likely not be SQ encoded because their records were mostly dual inventory. If they had made SQ encoded cassettes, I would have expected them to try to charge a premium, just as they did with the LPs.

    Thank you all for responding to my question.

    Several of the Syntonic Research Environments cassette tapes are matrix encoded but they do not reveal which encoding system they used. The liner notes only indicates the "tapes are matrx-encoded for quadraphonic playback"

    No actual experience myself but the editorial comments in the trade mags (High Fidelity and/or Audio and/or Stereo Review) was that the resulting phase errors from the decoding coupled with this mediums playback anomalies would not make for a stable listening experience.

    Not quite a cassette, but I have a very cheesy-looking 8 track with four programs and a logo that says "SQ - stereo quad encoded" (not the usual SQ logo though). It's "A Time For Love Vol. 2", Mirex MI655b (1974). Needs rebuilt and I dread the thought of what it would sound like anyway.

    Leaving the technical aspect aside--probably a good idea at the moment--I think it's safe to say if a recording was issued ONLY in SQ or QS format, if it were issued on cassette, reel, or 8-track, then that mastering would too be decodable just as the vinyl would have been. In other words, if you have a tape of any of the Angel SQ's or Impulse! QS's, then these should be the same encoding regardless of the sound carrier. How well these tape sources would play back and decode is harder to say, although the quality of reel tape would suggest that would, if available, be the best choice.

    But for those recordings that were issued both in stereo and quad, the odds are very much against (if always remotely possible) the tapes being anything other than stereo. A title or two might have slipped out with an SQ master, but I doubt that was likely with Columbia/Epic, since all the tapes I've heard of titles issued in quad seem to be stereo on whatever tape sources exist.

    I have 3 of those Syntonic cassettes...
    Don't ask me how or why I got them but
    I do believe they were SQ.

    I took some of my cleaned up SQ LPs and transferred them to reel to reel
    and played them back through my Sony SQ decoder just playing around to see what would happen and it didn't sound too bad.
    Obviously nowhere near what a true 4 channel tape would sound like but...
    it left me to wondering why Columbia didn't break through the stereo reel market with an SQ encoded quad compatible reel.
    Not that Columbia never got into quad reel tape anyway.
    At least not commercially.


    (Now I have like 15 reels of those "experiments" sitting on a shelf!)

    Nobody mentioned the EV and QS cassettes released by Ovation Records. They also did both matrixed and discrete 8 track tapes, and I think they had some discrete quad reels. Radio Shack also had some EV-encoded cassettes and 8 tracks as well.

    This affected SQ a lot more than it affected QS.

    True. Ovation did release EV- and QS-encoded cassettes, and even 8-track tapes. They also did discrete Q8's. Very few cassette decks could play these cassettes with good results
    because of the phase distortion that came from a number of problems, such as misaligned heads. High speed duplication doesn't help, either.

    Azimuth IS ONE aspect of alignment, there is of course also head height. I suspect that if azimuth were off far enough to cause a big phase error, it would also be quite noticeable in the high-frequency losses, considering how slowly cassette tape moves. If the error were, say 10* at 20 kHz, that would only be 2.5* at 5 kHz, better tolerance than the phase shifters in most SQ decoders. SQ being a "phase matrix" (you KNOW Sansui is right!) with rear channels defined by phase shift alone, it may suffer more than QS would, not sure, though. I have recorded QS and "Stereo-4" onto cassette, and decoded it just fine. Mileage varies with deck and tape, I'm sure, I used a tired old Tascam 122 deck with less-than-master-grade cassettes.
    Somebody out there with more time than I and a better calculator can no doubt figure how far off in degrees the azimuth must be to produce a given phase error at a given frequency...anybody? (Or cheat and use a tone generator and a vector-scope :>)

    There are actually 5 different parameters to head alignment, although some are fixed on many decks:

    1. Azimuth - Adjusting the angle between the line passing through the head gaps and the edge of the tape. Should be 90 degrees. Matches the head gap angle on the recording.

    2. Altitude - Adjusting the height of the head to center each head gap on the tape track. Minimizes crosstalk.

    3. Perpendicularity - Adjusting the head so the top edge of the head pushes against the tape by the same amount the bottom edge does. Makes sure that all tracks contact the head equally.

    4. Skew - Making sure the gaps are in the center of the area on the head the tape contacts (not near one edge of the contact area). Prevents dropouts.

    5. Protrusion - For cartridge and cassette decks, making sure the head protrudes enough to use the pressure pads, but no so much that it wears the tape.
