Indoor/Outdoor/Wall IP SIP Speaker
The AD638 IP-SIP loudspeaker is part of a series of TEMA loudspeakers to be connected in a standard LAN for public address Paging (PA) audio announcements, prerecorded messages and music, in offices, companies, hotels, medical clinics, hospitals, public places, schools, etc.
AD638 is particularly suitable when sound power and high sound quality is required at the same time with a pleasant and attractive design. The system, unlike the other models in the series, incorporates 2 speakers for low-medium and high frequencies sounds. The AD638 also incorporates a quality microphone for bidirectional communications and allows all the extended services of the AD63x SipComStage series.
The systems are equipped with PoE power supply to take direct power on the UTP cable and an input from an external 230Vac/12-24Vdc power supply to double the maximum power output.
Power Amplifier Technology
Two amplifiers in class “D” with high efficiency and low power consumption generates 40W (2x20W) and is self-protected against overloads and short circuits at the outputs.
In the internal SD card are recorded sounds and messages for automatic or command sending onto speaker, also automatically at pre-set times daily and weekly.
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
AD638 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.
Innovative features and performances
Ideal for creating Paging PA (Public Address) audio systems of any size using the existing LAN network infrastructure! Perfectly integrated with the PBX and the security system.
