TOA Electronics IP-A1PG PoE-Powered IP Paging Gateway
The IP-A1PG is a PoE-powered Gateway Unit that integratesmultiple IP Audio devices by converting the SIP voice or ONVIF Backchannelaudio into multicast audio streaming. It can also transmit built-in soundsource or input audio as multicast audio streaming. Moreover, the eventbroadcasting triggered by control input or remote API (HTTP) as well as thecommand set that sends multiple HTTP commands simultaneously are alsoavailable.
Key Features
- Convert SIP audio, ONVIF Audio Backchannel, internal audiofiles or local audio source into Multicast streaming
- System mute function to mute all broadcasts made by everysingle
- IP-A1 series devices within the same network
- 1 local audio input (LINE/MIC selectable, phantom powerOn/Off)
- 4 control inputs and 1 control output
- HTTP commands (receive/send)
- Audio file storage (20 files, total 80MB, WAV/MP3)
- PoE powered
