Comrex BRIC-Link III Stereo BRIC IP Codec

The Comrex BRIC-Link III, like the Comrex BRIC-Link, is a low-cost, high-performance solution for audio-to-IP conversion. Leveraging many of the core technical aspects of Comrex’s successful remote broadcast ACCESS product line, BRIC-Link III provides for an elegant way of moving linear or compressed audio with very low delay. BRIC-Link III is very simple to use, and can be deployed over a wide range of IP links. While it carries an entry-level cost, BRIC-Link II maintains superb audio specifications and hardware reliability, making the system suitable for STLs and other mission-critical functions without the expense required of more full-featured codecs. BRIC-Link III is contained in a small desktop package. Two BRIC-Links may be installed to occupy 1U of rack space.

Perfect for home studios, stadiums, and studio-to-transmitter links, this Comrex codec packs a powerful punch as a cost-effective, rock-solid, point-to-point IP audio solution that you can trust to do its job. It’s the “set-it-and-forget-it box” that’s beautifully boring – in the best way possible.

Now with a new, more powerful processor for improved performance and enhanced front panel for easy contact closure firing and auto-connects.
