AD633 is a two-way communication system with a built-in microphone with the dual local listening function and control of the speaker functionality.

Power Amplifier Technology
A double Class “D” Amplifier with high efficiency and low consumption can generate a maximum output power of 12W (2x6W) 8 ohms with high sound quality. The amplifier is selfprotected against overload and short circuit output power. It is provided a second auxiliary output which can be brought to another passive speaker to better distribute the output power or to generate a 100V-6W PA line.

Pre-recorded messages
In the internal SD card are recorded sounds and messages for automatic or command sending onto speaker.

iOS and Android APP
Free download APP are available for smartphones with operating systems iOS and Android. With these applications it is possible to operate with the IP speakers and launch announcements even from smartphones.

Integration with VoIP SIP phone systems
AD633 can be perfectly integrated with VoIP telephone systems (IP-PBX) with SIP protocol and can be registered as a regular VoIP phone or P2P (Peer to Peer) without a PBX.
