Product Overview

These tapes contain a series of recorded sine-wave signals for general-purpose use for standardizing azimuth, equalization, and sensitivity (usually called "gain" or "level") of open-reel analog audio magnetic tape reproducers. They are not intended for testing tape reproducer speed, flutter, distortion, or track placement.

The signals on these tapes can be monitored with a voltmeter—either the program level meter in the tape reproducer or an external voltmeter. Useful auxiliary test equipment includes a loudspeaker or headphones to hear the voice announcements of frequencies and levels, an oscilloscope to observe waveforms, and a level recorder in order to provide a graph of the frequency response.

Specifications:

  • Tape Width: 1/4" (6.3 mm)

  • Tape Speed: 3.75"/s (95 mm/s)
  • Equalization Standard: IEC & NAB
  • NOT Fringing Compensated
  • Level of Frequency Response Section: -10 dB
  • Catalog Number for Reference Fluxivity (250 nWb/M): 21F201-A
