It looks vaguely like 1970, maybe even 1980. Its online documentation is at avaya.com and it says Harris and Dracon on the documentation.

It's the brains of this: you pick up a phone and dial an extension. I don't know how this triggers the PagePac, but it records what you say, then you hang up. It then plays back the recording as a page in the zone that you chose by the number you dialed.

This particular one is the PagePac AmpliCenter 200, which seems to mean 200 watts, though it outputs to line inputs on the eight TOA amps below it.

The property has several buildings and the audio is at least 40% buzz. We need to clean this up, but we need to have a clue how it works first. I've downloaded something, but if you've had any experience with this beast, I'd appreciate any hints you might have.

Thanks.

Oh, yeah, this relates to the thread at [Link: remotecentral.com]. Those are the amps in the stack.
