Advent 101


The Advent Model 101 makes the considerable benefits of the Dolby Audio Noise Reduction System available to anyone who owns a good tape recorder.

By significantly reducing the normal proportion of background noise in a recording at any speed, the Dolby System yields a better overall signal to noise ratio and a quieter background level (virtually non existent noise in many cases) than previously possible.

Noise reduction makes lower tape speeds (3-3/4 and 1-7/8) usable for the first time for high quality music recording.
