The change to UHJ at that time is very small and was made just to get rid of the need for another phase shifter in the decoder (IIRC).
Any of the Classic Decoders, the Integrex, Minims, A&D etc will decode this properly. I for one would be most interested in a copy of the recording as it represents Calrec before I was a padawan. The people who recorded it were my mentors at Calrec and have passed on. _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
