Understanding Vinyl Matrix Numbers

Vinyl matrix numbers, often referred to as matrix or runout numbers, are inscriptions found in the dead wax area of a vinyl record’s label. They serve several important purposes:

• Identification: Matrix numbers help distinguish individual pressings of a record. Even if a record shares the same catalog number, the matrix number can differentiate between various editions, pressings, or reissues.
• Tracking: During the vinyl manufacturing process, matrix numbers assist in tracking and quality control. They help ensure that the correct stamper is used and that records meet the desired specifications.
• Copyright and Ownership: Vinyl matrix numbers sometimes include copyright information and ownership details, such as the name of the pressing plant or mastering engineer.

Deciphering Vinyl Matrix Numbers

To decode vinyl matrix numbers, you need to understand the basic format and elements typically found in these inscriptions. Here’s a breakdown:

• Catalog Number: The first part of the matrix number often corresponds to the record’s catalog number or label code, helping identify the specific release.
• Side Designation: Some matrix numbers include a letter (e.g., A or B) to indicate which side of the record it refers to. A “1” typically designates side A, and “2” designates side B.
• Mastering Engineer’s Initials: Occasionally, you may find the initials of the mastering engineer or technician involved in the record’s production.
• Pressing Plant Code: This crucial element identifies the pressing plant where the record was manufactured. Different plants may produce records with slight variations in sound quality and quality control standards.
• Sequential Identifiers: These numbers differentiate individual copies within a pressing run, often appearing as a combination of digits and/or letters.
• Copyright and Ownership Information: In some cases, the matrix number may include copyright symbols, ownership names, or additional information related to the record label or mastering process.

Example of Vinyl Matrix Numbers

Let’s break down a hypothetical vinyl matrix number to illustrate how to interpret it:

Matrix Number: ABC-12345-A-1A

• “ABC-12345”: This part could be the catalog number or label code, helping identify the specific release.
• “A”: The letter “A” indicates side A of the record.
• “1”: This could be the sequential identifier within a pressing run.
• “A”: This may represent the pressing plant or mastering engineer.

Tips for Interpretation

• Cross-reference with Label: To gather more information about your vinyl record, cross-reference the matrix number with the label, cover, and other identifying details.
• Online Databases: Numerous online resources and vinyl database websites can help you decode matrix numbers and gather information about your record’s pressing history.
• Variations: Keep in mind that matrix numbers may vary in format and content, depending on the record label and the era of production.
