Roberjerman, from somewhere in cyberspace,
“Yes. I have the Audio Pulse Model One Digital Time-Delay System. It was purchased new I believe in 1977 for over $700. The manual is very informative and well printed and is spiral bound. The effect on the sound in the room is very live sounding. One feature it has is the ability to make Mono recordings have a Stereo quality about them. Audio Pulse uses ninety separate shift register IC’s to provide delays of 8, 12, 22, 36, 58, and 94 milliseconds of discrete delay. Reverberation decay time: variable from 0.2 to 1.2 seconds, and those times are measured as the time for the reverb output to fall by 60 db after a transient.”
