About the Company

Ampex, founded in 1944 by Alexander P. Poniatov in California, was the pioneering American reel-to-reel manufacturer that commercialized high-fidelity audio tape recording in the late 1940s and dominated professional studio production through the 1970s–1980s.​ Ampex is widely regarded as the pioneer of professional magnetic tape recording in the U.S., supplying both studio-quality reel‑to‑reel audio recorders and industrial/instrumentation tape recorders. It was a key player in the U.S. broadcast, recording studio, and post-production industries for decades.



Key Production Timeline

1944–1947 — Company Formation & Early Projects

  • Alexander Poniatoff founded Ampex during WWII, focusing on electronics for military and industrial applications.

  • The first projects were industrial tape recorders and test equipment, not yet for mainstream audio studios. (Ampex History, Museum of Magnetic Recording)


1948 — Ampex Model 200

  • First commercially successful reel‑to‑reel tape recorder in the U.S.

  • Developed in collaboration with John T. Mullin, who brought German Magnetophon technology from WWII recordings to the U.S.

  • Significance: Marked the beginning of professional tape recording in American radio and music studios.


1950s — Expansion of Studio Tape Recorders

  • Introduced models such as Ampex 300, 350, 351, and 600 series, designed for high-fidelity music and broadcast recording.

  • These machines became the standard in U.S. radio stations and recording studios. (en.wikipedia.org)


1960s — Stereo and Multitrack Recording

  • Ampex MM-1000 (1965): First commercial 16-track tape recorder, a milestone in multitrack recording.

1970s — Professional Audio & Industrial Tape

  • Produced models such as Ampex ATR-102, the legendary 2-track mastering deck still used in mastering today.

  • Expanded into industrial, instrumentation, and military recording systems.

  • Introduced solid-state technology to replace older vacuum tube designs.


1980s–1990s — Shift from Tape to Digital

  • As digital recording emerged, Ampex pivoted toward video and instrumentation recording, eventually phasing out mass-market reel-to-reel audio tape decks.

  • ATR-102 and similar high-end professional decks continued in niche studio use.

Decline of Consumer Reel-to-Reel

  • Ampex never focused on consumer tape decks like Akai or Revox.
