Introduction

2N NetSpeaker

is an IP audio system which allows you to play an acoustic message

or any other audio stream from any LAN/WAN – connected PC. All you have to do to
get a virtual broadcasting exchange is connect a standard loudspeaker or amplifier to
your

. The virtual exchange helps you play any audio system and

2N NetSpeaker

create separate zones with different communication contents. You can make use of
your existing LAN/WAN while installing your

system to save the total

2N NetSpeaker

implementation time and, of course, cut your wiring costs.

The

2N NetSpeaker

ystem consists of two basic components – a server and an

audio converter. The Control Panel software has been developed to configure the whole
broadcasting system.

and

are software products

Console

Virtual Sound Card

designed for everyday use – broadcasting messages via a microphone and easy music
playing respectively.
