Convention Paper

A New Equalization Characteristic for Master Tape Recording

Authors: Goldberg, Abraham A.; Torick, Emil L.

AES Convention 11 · Paper 115 · October 1959

Abstract

Master tape recorders, running at 15 inches per second and using NAB equalization, are capable of providing a 55 db signal to noise ratio (peak record level to unweighted noise). Existing disc recording techniques had improved to a point where the audible master tape hiss became objectionable, especially during low level program material. An investigation of this problem resulted in a new equalization that reduces the hiss by 6 db. This work was done prior to the disclosure of the Ampex Master Equalization (AME).* It is gratifying to note the agreement in broad areas between Ampex and CBS data.
