Hal,
We tried initially. We were referred to an authorized Engineered Systems authorized dealer. District administration tried to get the dealer on site but after several phone calls with no estimates decided to find an alternate solution. Since the system is only being used as a glorified PA, there has been talk of abandoning the Multicom and replacing it with a Bogen GS150. Trying to give the MACPI2 a try before investing in the new amp and labor of re-terminating all the speaker/phone lines.

tim10,
Thanks for confirming the modules are compatible.
