NX-100
Network Audio Adapter
NX-100
The NX-100 Network Audio Adapter can transmit high-quality audio signals and such control data as serial 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).

The device shall be capable of simultaneous transport of audio, serial RS-232 data and contact closures. The device shall support three audio quality modes and have variable sample rate and audio bandwidth with a minimum latency/delay of 20 ms. Multiple error correction modes shall be available to address potential packet loss in high network traffic environments.
The network interface shall be 10BASE-T/100BASE-TX, Auto-Negotiation and utilize the network protocols TCP/IP, UDP, HTTP and RTP. The audio input shall be balanced, transformer-isolated, MIC/LINE switchable (-58 dBV to 0 dBV, 2k ohms) with adjustable volume control and plug-in screw connector. The audio output shall be balanced, transformer-isolated, (0 dBV, 600 ohms), with plug-in screw connector. Specifications shall include frequency response of 50 to 14k Hz and distortion of under 0.3% (1k Hz, sampling frequency 32k Hz).
The unit shall be capable of Unicast transmission to up to 4 simultaneous units/locations over LAN/WAN/Internet, and Multicast transmission to up to 64 simultaneous units/locations over LAN/WAN. The device shall include Java-based software for configuration, operation and management with password protected access. The device shall include a built-in web server for control and monitoring from any network-based PC with password protected access.
The control inputs shall include 8 channels, no-voltage make contact input, open voltage: 12 VDC, short-circuit current: 10mA with plug-in screw connector. The control inputs shall be individually programmable to initiate and terminate stored transmissions without the need for dedicated PC-based or other control equipment. Each unit shall have twenty programmable distribution presets. The control outputs shall include 8 channels, open collector output, withstand voltage: 30 VDC, control current: 50 mA max. with plug-in screw connector. Adjustable contact off delay time shall be available.
