The ELSII-10WM IP speaker features a 10W Class D amplifier powered
over PoE and delivering 95dB SPL. This two-way cabinet is desiged for
more versatile audio replication, and intended for environments where
aesthetic considerations are important.
With networked audio, 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.
