Outdoot IP SIP Projector

AD634 SIP projector speaker is part of a series of TEMA speakers to be connected in a LAN for the PA (Public Address) paging of ads, speech and music, in offices, factories, public places and outdoor.
The internal circuits incorporate a PoE power supply (Power over Ethernet) for direct power over UTP cable, but also allow input from an external power supply at 230Vac/12-24Vdc. The two power supply types can coexist in order to increase the safety of the service. AD634 is a bidirectional communication system with built-in microphone with local listening function and speaker-control functionality.

  • 1 3mt Patch Cord LAN UTP Cable for pre-installation test functions


Power Amplifier Technology

A high efficiency and low consumption double D-Class Amplifier can generate a maximum output power of 40W (2x20W) 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-20W PA line.

Pre-recorded messages

In the internal SD card are recorded sounds and messages for automatic or command sending onto speaker, also automatically at pre-set times.

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

AD634 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.
