The NX100S Network Audio Adapter can transmit highquality 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. The network audio codec shall be IPaddressable and convert analog audio (mic or line level) to standard IP packets for transport over an IPbased network including local area, wide area and the Internet. The device shall be capable of simultaneous transport of audio 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 10BASET/100BASETX, AutoNegotiation and utilize the network protocols TCP/IP, UDP, HTTP and RTP. The audio input shall be balanced, transformerisolated, MIC/LINE switchable (58 dBV to 0 dBV, 2k ohms) with adjustable volume control and plugin screw connector. The audio output shall be balanced, transformerisolated, (0 dBV, 600 ohms), with plugin 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 Javabased software for configuration, operation and management with password protected access. The device shall include a builtin web server for control and monitoring from any networkbased PC with password protected access. The control inputs shall include 8 channels, novoltage make contact input, open voltage: 12 VDC,shortcircuit current: 10mA with plugin screw connector. The control inputs shall be individually programmable to initiate and terminate stored transmissions without the need for dedicated PCbased 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 plugin screw connector. Adjustable contact off delay time shall be available. The front panel shall include Link/Active, FullDuplex/Collision, Signal, Peak, Status, Error, Run LED indicators plus recessed Reset button. Firmware shall be FLASHtype and upgradeable from any network PC. Power requirements shall be AC adapter (optional) with 24 VDC output with current consumption of 200 mA. The finish shall be black steel plate, 30% gloss. Dimensions (W x H x D) shall be 8.27” x 1.81” x 7.4” (210 x 46 x 188 mm) and weight shall be 2.65 lbs. (1.2 kg).
