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.

As an over 50 year user ot analog tape, there is no better way to assure tape machines remain at their optimum. MRL has always been our go-to allignment tape since the 1970's. Proper setup for a particular tape type is a tedious process and a calibrated tape is a necessity. Must have one for each tape speed, too.
