About DADC Austria matrix numbers
Matrix indicators: 'Manufactured by DADC Austria' most probably in use until 1988 (represses occur), 'Mastered by DADC Austria' most probably until 1994, solely 'DADC Austria' most probably until 1998.
1987-1995: 'Label prefix-catalog number BB CC' (e.g. [logo] CDCBS-450152 43 A1, [logo] BIAS-47-CD 12 A1, [logo] SPOONCD-26 11 A1). CD-singles/Maxis only show 'Catalog number BB CC (e.g.'
1991-1997: 'nn-xxxxxx-yy BB CC' - (e.g. [logo] 01-468884-10 13 A12) - these nn-xxxxxx-yy numbers appear also on the face of the CD but only when manufactured for the Haarlem production cycle.
1995-1997: Axxxxxxxxxx-yyzz BB CC (e.g [logo] A0100181635-0101 15 A1)*
*pattern remained in use after renaming of the company, around A0000250xxx (~1998) the DADC Austria logo had more or less been replaced.
- For CD releases: 'A' indicates 'Anif', 'yy' indicates the disc number (always 01 for single-disc releases; 02 and onwards are used for multi-disc releases), while zz indicates the number of discs in the release (again, always 01 for single-disc releases). DVDs do not seem to use the same numbering for the yyzz part however.
- BB is a two digit number, usually between 11-25. The second digit is the same as the last digit of the mastering SID code (IFPI L55x).
- CC is printed into the matrix ring and is usually A1, A01, A00, B1, etc.
From 1994, DADC Austria glass masterings can be identified by Mastering SID code ifpi L55x
When entering DADC Austria matrix numbers into LCCN, ONLY the "Axxxxxxxxxx-yyzz" part of the string should be entered. An example of how to correctly enter the DADC Austria number is Burzum - Filosofem. The typical glass mastering indicators in the matrix - e.g. the logo - can certainly also be found on post-1997 reissues.
Please note that all submissions dated prior to July 1987 and all Columbia / Sony Music Entertainment branded releases submitted before 1991 must be considered as erroneous.
