NX-300 Network Audio Adapter
NX-300 W
The TOA NX-300 is a network audio adapter that utilizes packet audio technology (*1). Connecting the NX-300 to a network (LAN or WAN) permits high-quality audio or contact control signals to be transmitted in real time. As existing networks can be used, systems can be constructed with no need for the installation of new wiring. Broadcasts using audio files and up to 8 different levels of priority control can also be made, and provided by stations, factories or other central facilities to individual bases. It can be mounted in an EIA equipment rack (1U size) with the use of an optional rack mounting bracket or installed on a wall using an optional wall mounting bracket. (*1) TOA's unique technology which makes it possible to transmit high-quality audio signals in real time over an IP network.
