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.
