SoundLAN-E.UP devices are a family of IP amplified audio gateways that form the heart of the IP public address system
produced by ERMES. They are available with power ratings of 80W, 160W, or 320W and interface directly to the data network to
provide an audio output for 100V lines capable of driving one or more loudspeakers.
SoundLAN is an IP public address system based on native IP devices that use a Peer-To-Peer communication protocol
and connect directly to the ETHERNET network.
Thanks to the use of LAN for the interconnection of all elements, it is possible to implement Public Address and Paging systems
in a simple and economical way, especially in those cases where the considerable distances involved make it expensive and
sometimes impossible to implement traditional analog systems.
The SoundLAN system, in fact, overturns the traditional system layout of analogue sound diffusion systems that provide for
the installation of amplification equipment in a single centralized cabinet from which the 100V lines that feed the loudspeakers
installed in each zone to be sonorized depart, to pass to a solution that provides for the installation in each zone of an audio
gateway (amplifier in IP) that receives from the data network the audio stream to be reproduced and on whose output are connected
the loudspeakers of the zone.
Such a solution has multiple advantages:
if the area where you want to install the public address system already has a data network there is very little work work to
install it because the IP public address system can share the existing data network with any other system already installed
saving time and costs on installation
since the audio signal is transmitted in digital way there are no limits to the distance that the transmission of the audio
can cover and therefore it is possible to implement systems in geographical area too by transmitting audio streams even through
the public data network
if necessary, it is possible to modify in a very simple way the structure of the system either by adding new playback units
or by adding new microphone consoles without the need to modify the existing system and thus saving the previous investments.
the quality of the audio signal is always high and without any kind of degradation regardless of the distances that need to
since the transmission protocol and the coding system for audio that ERMES uses for the public address systems is the same
as that used for intercom and emergency call systems, it is easy to create systems in which, for example, a single amplified
gateway make both the function of intercom and the function of IP audio amplifier
(seeHERE a case history).
The system shown in the block diagram can be controlled from a simple desktop console such as the InterLAN-EO.PPM, but in the
case of complex systems with a large number of areas, it may be easier to use the SoundLAN.SW software installed on a PC that
allows you to manage a wider range of functions.
Some of the functions implemented by means of this software are the automatic broadcasting of announcements in different zones
on the basis of a timetable, the broadcasting of background music, WebRadio playback and other similar functions.
All in all, SoundLAN IP audio amplifiers, together with the other devices in the family, make it easy to set up IP-based
