1.1 Product Description
The 2N®NetSpeaker System is a universal sound transmission system for IP
networks. Its purpose is to replace classic wire broadcasting systems using a
broadcast centre, obsolete 100V analogue circuits and loudspeakers. It finds a variety
of applications - in schools, hospitals, office buildings, hotels, production halls,
shopping centres, bus terminals, airports and so on. Compared with the classic
analogue solution, the system has a lot of advantages: uses the existing LAN
infrastructure, provides easy connection to vast or remote areas, helps users send
anything from anywhere to any place, shows no zone or sound source limitations and,
in general, is very flexible and easily extendable.
2N®NetSpeaker is a stand-alone sound decoder and converter with an amplifier
working as a terminal audio device for the 2N®NetSpeaker System. 2N®NetSpeaker
communicates with the 2N®NetSpeaker System via the local area network (LAN),
decodes the audio stream converting it into an analogue signal, which is then
amplified by an integrated power amplifier.
2N®NetSpeaker is available in two versions:
Module with an amplifier (Part No. 914010E), which can be connected to an
external loudspeaker/an external amplifier or used with headphones.
Module with an amplifier and a loudspeaker (Part No. 914020E), designed for
direct wall mounting (wall/flush/ceiling mounting).
This User Manual applies to Part No. 914010E.
