    LX-IP Synchronous AoIP & MADI Multichannel Sound Card

    Key Workflow: Bridges professional audio software applications to the ultra-low latency, phase-accurate and high precision clock management of AES67 and RAVENNA AoIP networks

    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.

    At a glance

    The LX-IP sound cards provide:

    • 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

    Key features

    • 64/64 Record/Play channels on PCIe bus
    • 64/64 AES67/RAVENNA I/O channels on each of the two Gigabit Ethernet interfaces
    • 64/64 I/O MADI (AES10) optical channels (option)
    • Ultra-low sub-millisecond round trip latency
    • Fully compliant with AES67 interoperability recommendations, including Unicast SIP support
    • Packet size from 128 down to 1 audio sample per RAVENNA packet
    • Local clock eligible as PTP Grand Master
    • Zero delay embedded routing matrix for AoIP / MADI / PC channels
    • Performance maintained regardless of the computational load of applications running on the host system
    • Fully configurable through Web user interface and EMBER+ protocol

    Benefits

    • Seamless migration to IP: High density, ultra-low latency and phase accurate AoIP / PC / MADI bridge
    • Secure content delivery: HW-based permanence of service whatever the applications running on the host PC
    • Same latency as Digital audio: Sub-millisecond round trip latency
    • Ensure interoperability: LX-IP is fully compliant with triple standards AES67, RAVENNA and MADI (AES10)
