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