Nagra III portable tape recorder, 1958-1969.

Very high quality portable audio recorder usually used for film sound recording and sound gathering. It is a solid-state machine, with the tranistorised modules enclosed in metal cases. It is powered by conventional “D” type batteries. There is a true peak meter called a “Modulometer”. Over 10,000 Nagra III recorders were sold.

Stefan Kudelski introduced the “Neopilot” system and the first NAGRA III machines equipped with the system appeared in 1962. "Neopilot" was the standard synchronization system used to synchronize sound and vision elements until the late 1980s, when time code became the preferred standard.
