TOA NX-100 SERIES NETWORK AUDIO is a reliable and easy to use solution for transporting mic or line-level audio signals over IP-based local and wide area networks (LAN/WAN), as well as the Internet. Applications include wide area paging, background music or messaging audio distribution for airports, convention centers, railway stations and transit systems.
The flagship model NX-100PS US transports variable bandwidth, bi-directional audio, up to 14 kHz, as well as serial RS-232 and contact closure data. Each half-rack sized unit includes a balanced mic/line input and output and a 10/100 BaseT Ethernet jack for connection to standard network hardware. The rear panel includes eight programmable trigger inputs to initiate and terminate audio transmissions, eight programmable open collector control outputs and an RS-232 serial port for data transmission/reception.
NX-100PS US also has a built-in web server to support browser-based programming, control and monitoring from any network-connected PC. Other features include multiple error correction modes, external 24 VDC input, and Flash-upgradeable firmware.
