Introduction

2N IP Audio system

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

Net Audio Decoder

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

Net Audio Decoder

system to save the total implementation time and, of course, cut your wiring costs.

The

2N IP Audio system

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

2N IP Audio

Console

2N IP Audio

Virtual Sound

are software products designed for everyday use – broadcasting messages via a

Card

microphone and easy music playing respectively.
