TOA extends its emergency credentials over IP

Capable of decoding IP audio streams into analogue audio signals, TOA has added a PoE-powered audio interface to its catalogue. The IP-A1AF is equipped with an integrated 15W amplifier to drive low-impedance speakers and internal memory, capable of storing up to 20 audio files, although an external amplifier can also be connected to the analogue audio and control outputs.

Capable of receiving broadcasts from Video Management Systems via ONVIF backchannel, device control is accessed through remote API (HTTP) or local control inputs. The PoE-powered Gateway Unit integrates multiple IP audio devices by converting the SIP voice or ONVIF backchannel audio into multicast audio streaming and the IP-A1AF can also transmit built-in sound sources or input audio as multicast audio streaming.

Equipped with a built-in 8W amplifier and internal data storage for up to 20 audio files, the IP-A1PC238 and IP-A1PC580R are PoE-powered ceiling speakers. Both models support the SIP protocol for integrations with VoIP devices and come with 20 available multicast ports for group paging operations. Boasting the same features, the IP-A1PC580S is a PoE-powered surface mount speaker.

Connection to the VMS network via a single LAN cable and assigned an IP address, the IP-A1SC15 can combine both video and audio systems. Live announcements or pre-recorded messages can be prioritised for broadcast during emergency situations with one of four different audio broadcasting modes (SIP Direct Call, Multicast Streaming, VMS Broadcast and Remote API).

An IP Setting Tool can assign IP addresses to all IP horn speakers during setup. Once network and host ID has been established on one speaker, all others are automatically assigned IP addresses for the remaining devices. Each IP horn speaker can be individually tuned by adjusting settings dependent upon height, distance and speaker environment.
