Public Address with VoIP Distributed Amplification

Building Block Typical Diagram

Features:

• Full integration with Intercom and Telephone Systems.

• Distributed amplification (alternative or integrative to a centralized amplification) performed through the use of IP self-amplified loudspeakers with built-in power amplifier.

• IP self-amplified loudspeakers (max power output: 25W with POE+ and 10W with POE), capable to be remotely configured and monitored, and fitted with ALC (Automatic Level Control) of the output power according to the variation of the ambient noise level.

• Extended intercom operation between access panels (omnibus page/party, selective point-to-point, group calls and conference calls), with virtually unlimited number of simultaneous conversations.

• Paging zone calls (including single zones, any combination of zones and all zones).

• Alarm tones and/or prerecorded messages zone broadcasts (including single zones, any combination of zones and all zones).

• Broadcast of pre-recorded messages and music through radios, CD readers and MP3 players.

• Main Public Address / Intercom stations (access panels) VoIP based, fitted with handset and keypad. If required, also equipped with gooseneck microphone and additional 40 buttons (up to 48 in total) keypad for direct activations.

• Very cheap and cost-effective cables network (LAN network to interconnect all access panels and one standard power pair for each speakers' loop).

• All access panels can be connected with a maximum allowed distance of 250 meters from the relevant LAN switch (instead of 100 meters as per usual standard).

• System architecture allowing, in case of fault of a field device, the complete operation of all other field devices even in case of multiple fault events.

• Interfacing with plant Telephone System, plant Radio System and with existing Public Address and Intercom Systems.
