2. SUMMARY AND FEATURES
The IP-A1AF is an IP Audio Interface which decodes IP audio streams into analog signals.
It is equipped with a built-in 15 W amplifier to drive Low-impedance speaker(s).
Analog audio and control outputs can be connected to an external amplifier for scaling up the
system capability.
• 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.
3. ABOUT SECURITY MEASURES
• Ensure that sufficient security measures are taken on the customer’s own responsibility.
• TOA Corporation takes no responsibility for damage or loss caused by security-related problems,
such as illegal access.
• To help prevent illegal access to the unit, be sure to change the user ID and password from those
used for initial setup. For setting methods and other details, please refer to the separate setup
manual which can be downloaded from the TOA DATA Library (https://www.toa-products.com/
international/).
• Take utmost care in the management of the unit’s communications password.
