SUMMARY AND FEATURES

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.
