STL-IP
Designed for broadcast use in Radio and Television, AudioTX STL-IP is an easy to use, cost-effective solution to audio delivery over IP networks. It is a new Oldproduct that is absolutely unique in offering the same quality, robustness and low delay as conventional audio circuits, but with the flexibility and low cost associated with using IP connectivity.Features
AudioTX STL-IP IP codec provides for live audio transmission over IP networks with transmission grade audio quality & robustness and extremely low delays - as low as 5ms!- IP Codec for live audio: Transmit and receive audio using point-to-point UDP or TCP/IP, and point-to-multipoint UDP Multicast network protocols over ANY IP Network - including private networks (LAN/WAN), Satellite, Wireless networks, T1/E1, ATM or the Internet.
- A single STL-IP system can transmit audio on up to six simultaneous connections, each using different audio coding and network protocols if required. Using Multicast, audio can be sent to an unlimited number of destination units. Audio can be received from one remote location, independently from transmission.
- AudioTX STL –IP works with linear (uncompressed) audio at up to 24 bits and 96kHz sample rate, or compressed audio via built-in Professional Grade MPEG Layer 2 or MPEG Layer 3 coding/decoding, J.41, ADPCM, G.722 or our extra Low-Bitrate speech codec.
- Optional Forward Error Correction (FEC) and network jitter compensation where required.
- Synchronous transmission of serial ancillary data and/or contact closures (TTL GPIO).
- Built-in silence and audio overload detectors.
- Monitor and control via web-browser control interface, SNMP traps and queries, E-mail alerts, Telnet style IP remote control interface (using simple text commands and responses), included software and logic level status outputs.
- Incredibly flexible and cost-effective solution.
AudioTX STL-IP can send live audio using up to 6 simultaneous connections - including any combination of UDP, TCP/IP or UDP Multicast (to an unlimited number of destinations for each UDP Multicast connection). The IP Codec system can receive audio from one location.
