LX-IP provides the perfect gateway from mission critical applications to RAVENNA and AES67 AoIP networks. Its 64 channels, 0.5 ms latency and phase accuracy match all requirements for high density, ultra-low latency on-air or production studio workflows. Hardware-based architecture maintains performance regardless of the computational load of other applications running on the host system.
LX-IP with MADI optional interface provides a seamless migration path from legacy digital audio to AoIP and provides all MADI features described below.
- High channel count, ultra-low latency and phase-accurate audio distribution on synchronous AoIP networks
- Phase-accurate clock synchronization between digital audio and AoIP networks
- Interoperability with traditional digital audio
- Performance & stability independent of PC applications
- Mission critical reliability
- Play/record 64 audio channels between a DAW (Digital Audio Workstation) or automation application and AES67 or RAVENNA synchronous AoIP network
- Play/record 64 channels between a DAW or automation application and digital audio MADI equipment
- Provides zero-latency routing on-board between 2*64 RAVENNA/AES67 channels, 64 DAW channels and (option) 64 MADI channels
- Provides PTP Grand Master clock to synchronous AES67 or RAVENNA AoIP network. This Grand Master can be slaved to WordClock or MADI inputs
- Synchronises RAVENNA/AES67 AoIP streams on external PTP clock. The MADI output and WordClock clocks can be slaved to the external PTP clock
