The NX-300 uses an advanced implementation of its Packet Audio™ streaming technology (same as NX-100) with improved broadcast capacity and system expandability, WAV file record functions and addition of other advanced features. The NX-300 can be used to create wide area PA and announcement systems over any IP network. Ideal for railway systems, airports, regional business broadcasts, Bank ATMs, parking system communications and industrial facilities.
