Introduction
2N IP Audio system
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 any2N 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 2N 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 aCard
microphone and easy music playing respectively.
