The MGV-4000/PA controller from Trans Data Management enables the routing of audio inputs to connected speaker zones with features including simultaneous announcements, speaker selection, and priority levels. It supports VoIP communication, provides recorded evidence of announcements, and allows remote configuration. The system meets several safety and EMC standards, operating under various environmental conditions and providing several interfaces and protocol support.

1. Features
 Up to 8 simultaneous announcements
 Speaker zone/group selection (line-based or serial protocol)
 Priority announcements
 Wideband audio
 Local pre-recorded announcement can be triggered by external events
 Simultaneous streaming to the voice recorder on TDM’s NIS system
 Integration into maintenance centre of TDM’s NIS system
 Remote configuration and software download
 Support DNS/DHCP
 Hot-swappable, field-replaceable front-end boards
The MGV-4000/PA Controller from TDM allows routing of audio inputs from different sources to the
connected speaker zones. The controller converts the VoIP audio codecs into analogue signals as input
for the connected amplifiers and their speakers.
The zone selection feature allows the operator or dispatcher to select dedicated speakers to broadcast
an announcement at a specific location. Each broadcast can be assigned a priority level, those with a
higher priority will take precedence over announcements of lower priority.
All announcements are duplicated on the MGV-4000 /PA Controller and forwarded to the voice recorder
on TDM’s NIS system; providing recorded evidence of each audio announcements.
