NX-100 Network Audio Adapter


The NX-100 Network Audio Adapter can transmit high-quality audio signals and such control dataas serial data over IP networks, such as LAN or Internet, in real time. It is especially useful whentransmitting audio signals to remote locations, as Internet use keeps running costs lower than theuse of dedicated lines. With the use of an optional rack mounting bracket, it can be mounted in anEIA Standard rack(1 unit size).
