The perfect gateway to RAVENNA and AES67 networks.
from mission-critical applications


When working with RAVENNA AoIP and AES67 networks on mission critical applications, our LX-IP card is the perfect addition to bridge professional audio software applications: it brings ultra-low latency, phase-accurate and high precision clock management of AES67 and RAVENNA AoIP networks. So seamless you don’t even notice the difference.  

Perfectly suited for on-air or production studio workflows, you will enjoy the full power of 64 channels, 0.5 ms latency and phase accuracy. Operating several applications at once? Our workhorse LX-IP has a hardware-based architecture that maintains performance regardless of the computational load running on the host system. Keep on!

LX-IP with MADI option provides a seamless migration path from legacy digital audio to AoIP and provides all MADI features described below.

    How to retrieve the IP addresses of the LX-IP

    The best way is to use Wireshark and directly connect your LX-IP card to your computer, after setting a capture filter to exlude your PC's IP address to narrow the displayed messages.
