TOA Electronics IP-A1PG PoE-Powered IP Paging Gateway

The IP-A1PG is a PoE-powered Gateway Unit that integrates multiple IP Audio devices by converting the SIP voice or ONVIF Backchannel audio into multicast audio streaming. It can also transmit built-in sound source or input audio as multicast audio streaming. Moreover, the event broadcasting triggered by control input or remote API (HTTP) as well as the command set that sends multiple HTTP commands simultaneously are also available.

Key Features

• Convert SIP audio, ONVIF Audio Backchannel, internal audio files or local audio source into Multicast streaming
• System mute function to mute all broadcasts made by every single
• IP-A1 series devices within the same network
• 1 local audio input (LINE/MIC selectable, phantom power On/Off)
• 4 control inputs and 1 control output
• HTTP commands (receive/send)
• Audio file storage (20 files, total 80MB, WAV/MP3)
• PoE powered
