Stream audio and broadcast announcements and pre-recorded audio with the Toa Electronics IP-A1AF, a PoE-powered network IP audio interface that decodes IP audio streams into audio signals. The interface is fitted with a 15W amplifier to drive low-impedance speakers. Additionally, the analog audio and control outputs can be connected to an external amplifier for scaling up the system capabilities.
The interface supports SIP protocol for flexible integrations with VoIP devices, and its 20 multicast ports are available for group paging operations. The IP-A1AF can also receive broadcasts from Video Management System via ONVIF audio backchannel. Additional control and system integration is accessed through remote API (HTTP) or local control inputs.
- Receive SIP audio, ONVIF Audio Backchannel and Multicast
- Local broadcast using internal audio files or local audio source
- 1 audio input (Line/Mic selectable, phantom power On/Off)
- 8W (PoE) / 15W (PoE+) built-in amplifier, 1 Line audio output
- 2 control inputs and 1 control output
- HTTP commands (receive)
- Audio file storage (20 files, total 80 MB, WAV/MP3)
- Playback programs (Repeat, Weekly Timer)
- PoE/PoE+ powered
- Power is supplied by way of PoE+ (IEEE 802.3at) or PoE (IEEE 802.3af) switching hubs
- The IP audio interface is compatible with the following broadcasting modes:
- Internal sound source broadcasting mode: enables broadcast of up to 20 internal sound source files by means of control input or Remote API (HTTP)
- VMS broadcasting mode: enables backchannel audio broadcast from the VMS (Video management system) software using the common protocol for IP cameras
- SIP broadcasting mode: enables SIP broadcasts from any voice communications device that utilizes the SIP protocol, such as SIP or IP telephone (IP-PBX) systems
- Multicast broadcasting mode: allows up to 20 multicast ports to be set up, for 20 multicast audio stream paging groups
- Local broadcasting mode: local broadcasting mode enables broadcast locally to the speaker output and the LINE output from the sound source device or microphone connected with LINE/MIC input
- Orders of priority can be set among the various broadcasting modes, meaning higher priority broadcasts can interrupt and override lower priority broadcasts
- Since the unit is equipped with individual offset adjustable volumes for each broadcasting modes and patterns (internal sound source), actual broadcasting volume can be normalized or optimized
- Broadcasts can be controlled using Remote API or control inputs from connected external equipment
- Connected external equipment can be controlled by control outputs in synchronization with speaker broadcasts
