Just installed a new valcom paging system in a school. We are using a V-2924A with a V-2925 Expansion unit. All wiring is new and each speaker in wired individually except for the common areas (Hallways, lunchroom, etc.) Pages work fine but we get a constant hum on the speakers. It appears to be a power problem-if we disconnect the talk pair the hum persists. Anyone have any ideas?
