It was originally ordered for the American secret services and was even taken to the moon on one of the Apollo missions.

Key features

The SN solves film-makers’ synchronous sound recording problems: it can easily be concealed during filming and strict synchronization is guaranteed. For scientific research, the SN can also record data while on board a propelled craft.Reels of narrow 1/8″ (3.81 mm) tape are used, and tape drive is by a slaved capstan motor. Rewind is manual but rapid thanks to an overdrive system, using a small folding crank handle.

There are different versions of the recorder:

  • NAGRA SNN full-track recording, 3 3/4 and 1 7/8 in./sec. (9.5 and 4.75 cm/s)
  • NAGRA SNS half-track recording, 1 7/8 and 15/16 in./sec. (4.75 and 2.38 cm/s)
  • NAGRA SNG
  • NAGRA SNST
  • NAGRA SNST-R

The tape-deck is milled from a solid piece of metal and the case and lid are of drawn light metal alloy.

All electronic circuits are highly sophisticated and include a voltage converter with variable ratio, and an automatic level control. A special miniature omnidirectional capacitor microphone can be used and it is also possible to work with a conventional dynamic microphone.

A small meter indicates the compression rate of the automatic level control or the battery voltage. Headphones can also serve as an output monitor (confidence playback).

High-quality recording and sonic excellence

The Nagra SNST-R has a frequency response of 50 Hz to 15 kHz ±2 dB. The wow and flutter performance of 0.05% is also state-of-the-art. Its small size renders it an ideal candidate for all portable, location or discreet recording applications. The machine uses 0.15” (3.81 mm) tape on special open reel spools. Operating at a tape speed of 3.75 inches per second (9.5 cm / S), it yields duration of approximately 40 minutes per reel of tape. The Nagra SNST-R uses two “AA” size batteries or rechargeable cells. This enables more than 5 hours of operation.

Connectivity

Two connection sockets on the left-side allow the connection of either the two accompanying Beyer dynamic microphones or the line input cables. The outputs are available on the two 3.5 mm jack plugs, located on the front edge of the SNST-R. They can be used either for connecting the headphone (with an impedance of 2 x 600 Ω) or the line output cable.
