Fellow pro-am audio guy here.
Do you know anything about the Summer Jam at Watkins Glen in 1973?
There’s an ad in the current TapeOp magazine for a Eventide 500 series hybrid analog/digital delay referring to this concert as the (presumed) first use of digital delay timing in a live audio PA to synchronize the the huge speaker stacks deployed for the 600,000 person (!!) concert.
Using delay is all standard ops and procedures today, but I’m a huge fan of tuning (much smaller) systems with delay timing. The first time I figured out how to use something like a DriveRack PA to not only get the crossover points and slopes right but the inter-speaker delay timings right as well was practically a religious experience for me.
It makes a sound system sound so much better, punchier and cleaner even though the differences are often just microseconds or milliseconds in even a 6 cab tri or bi amped club or outdoor mobile sound system.
I’m really curious about any history you know about this Digital Delay Line system, produced by what appears to be “Eventide Clock Works” according to the badging on the units shown in the picture in the ad.
