We have been approached by a customer who has an existing Page Pac D20 in their facility that was originally used behind their Legend. They now have it connected to their IP system using an SLA of some sort. Over time, employees either removed or sabotaged many of the speakers. Now, the customer would like for us to put everything back together. What I need to know is:

1. There is a multi-zone adapter connected to the D20 amplifier. It appears to have four zones of speakers wired to it. How many total zones can this accommodate?

2. Is this a 70 volt system? The original installation has spare pairs in tie cables being used, and it appears that each zone uses two pairs. I'm not sure of this.

3. What kind of speakers should be used? Are the ones originally made for Lucent even available anymore? If so, is someone like Bogen making them?

Any help will be greatly appreciated.
