This Zenitel IP Projector speaker features two 130mm full-range loudspeakers driven by a 10W Class D amplifier, powered over PoE. This means that the speaker is capable of delivering upto 97 dB, depending on the signal input. the Bi-directional speaker design allows for a balance between the directivity of a horn speaker, and the visual considerations of a cabinet speaker. This speaker is ideal for installation on walls or at ceiling level for audio along corridors, walkways, air-bridges and platforms.

With networked audio devices  the system is able to monitor and address each speaker individually. By moving the amplifier from a central unit out to the speaker itself, the need for a central amplifier unit with conventional speaker loops is eliminated. This makes the system highly scalable, and adding another speaker is easy to do.

Whilst conventional speaker loops are not used, the speakers can still be divided into groups. These zones can now extend over networks or span the Internet.To provide maximum availability, the speaker comes with advanced supervision functions.

The built-in microphone enables intelligent features such as Self-checking, and Automatic Volume Control. It also enhances what is traditionally a broadcast-only medium adding Half Duplex speech, and Ambient Listen functions. Self-checking will detect whether there are any faults in the network or speaker electronics. The status of the speaker is reported to the central unit as well as to 3rd-party management systems using SNMP or Syslog. The speakers can also be discovered, receive messages, and use Talkback direct to a VMS over ONVIF. 

The speaker has a built-in web interface for status information, control, and upgrade. It is easy to install and maintain. In addition, there are possibilities where broadcasts can be logged in detailed reports.
