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.
Basic Features
10/100Base-TX LAN interface
12V DC/2A or PoE 802.3af power supply
Integrated 14W STEREO/MONO amplifier
Line/headphone output
Colour LED operation status indicators
Universal galvanically isolated output
Universal digital input
MicroSD card slot
Two universal programmable buttons
Infrared remote control

2.1 Product Description
2N®NetSpeaker is a LAN audio converter designed for public sound distribution
through the 2N®NetSpeaker System. It is connected to the 2N®NetSpeaker System
via the local area network (LAN). It communicates with the 2N®NetSpeaker Server,
receives the audio stream, decodes it and converts it into an analogue signal.
2N®NetSpeaker is equipped with an integrated 14W amplifier for direct loudspeaker
connection.
2N®NetSpeaker can be controlled by two front panel buttons or an infrared remote
controller.
2N®NetSpeaker is equipped with a digital input and output, which extend the
converter options and may be helpful in special applications.
2N®NetSpeaker helps you extend the internal FLASH memory using MicroSD memory
cards.
Use the integrated Telnet server to make basic settings for connection of 2N®
NetSpeaker into the LAN (refer to the Basic Parameter Settings). Apply the 2N®
NetSpeaker Software for configuration and use of all functions (refer to the
2N®NetSpeaker Software User Manual).
