Ready out-of-the-box so forget hardware card upgrades, just connect and go! Supports 2 AES67 streams.
ST 2110-30 Ready
SMPTE ST 2110-30 compliant out-of-the-box.
SmartStream PLUS redundant streaming
Connect multiple IP links to codecs and use SmartStream PLUS to stream simultaneous redundant data streams and deliver seamless redundancy when streaming over IP.
Bond multiple interfaces with Fuse-IP
Imagine the peace of mind knowing you can bond data links from different Telcos and let Tieline’s Fuse-IP technology automatically manage the data capability of each link!
Flexible Audio Distribution
The Gateway-4 supports multi-unicasting and multicasting for audio distribution.
- Multi-unicast mono or stereo to audio to up to 20 endpoints in total.
- Multicast mono or stereo audio to unlimited endpoints over compatible networks
- Gateway-4 multi-unicasting to up to 20 codec endpoints
- Gateway-4 Codec Delivers 4 Mono Connections
Multiple Backup Options
The Gateway-4 has multiple levels of power, audio and network redundancy. The codec features dual Gigabit Ethernet ports, dual AoIP ports, dual internal power supplies, automated audio silence detection and IP network backup solutions to ensure you’re always on the air.
Automated network failure detection provides auto switching to a backup IP connection. The codec can automatically switch between 4 backup audio sources to maintain program output at transmitter sites. It is also possible to fail over to ISDN using an optional ISDN module. IP fail over options include:
- Connection audio.
- Icecast streaming client.
- Audio file backup.
- Hardware bypass of audio inputs to outputs if power fails.
