John G. (Jay) McKnight was born in Seattle, Washington, in 1931. He received his BS in Electrical Engineering from Stanford University in 1952, and worked for Ampex Corp from 1952 thru 1972, except for the years 1953...1956 when he served in the US Army, at the Armed Forces Radio Service (AFRS) in New York City, where he also worked at the Gotham Recording studio. At Ampex, he served in the magnetic recording research group, the stereo tape division, and the professional audio division. At Ampex, in addition to research he also worked on the design of the CinemaScope reproducer system; the Models 350, PR-10, and MR-70; improvements in the high-speed duplication system and operating procedures at the Ampex Music (Stereo Tape) Division; and developed the "Ampex Master Equalization" (AME). He has published over 60 technical papers mostly in the Journal of the Audio Engineering Society (AES), on the theory and practice of magnetic recording, and on audio engineering (see the bibliography of these papers, with many links to the papers). He received the Audio Engineering Society's Publication Award in 1982.
He is a co-founder of Magnetic Reference Laboratory (MRL) in Mountain View, California, where he was Engineering Vice-president from 1972 to 1975, and has been the president since 1975. He also develops new products and directs engineering at MRL.
From 1972 to 1974 he was also a consultant to Scully/Metrotech in
Mountain View, CA, and to MCI in Ft. Lauderdale, FL, on audio systems and magnetic recording.
In 1973 and1974 he was a member of Judge Sirica's "Advisory Panel on White
