Product Description
TOA NX-300PS Network Audio Adapter
The NX-300PS US uses an advanced implementation of its Packet Audio™ streaming technology (same as NX-100PS US) with improved broadcast capacity & system expandability, WAV file functions and addition of other advanced features. The NX-300PS US 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 & industrial facilities.
The latest NX-300 firmware version is 2.0.1(update:2016/10/7).
The software version is 2.0.0(upload:2016/9/23).
