Comrex BRIC-Link II

List: $1,700.00






The BRIC-Link II is a low-cost, high-performance solution for audio-to-IP conversion. Like its predecessor, the BRIC-Link, BRIC-Link II provides an elegant way of moving linear or compressed audio with very low delay. BRIC-Link II is 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 perfect for studio-to-transmitter links (STLs) and other mission critical applications.


BRIC-Link II works with:

ACCESS Rackmount




  • Works on variety of data networks: T1/E1, ISM Band IP Radios, Satellite, WANs and LANs, public Internet connections
  • Low delay – less than 25mS in linear modes, less than 30mS in FLAC modes
  • Codecs – Stereo and mono linear mode, FLAC modes, AAC/HE-AAC modes, Opus, G.722 and G.711
  • Web-based user interface
  • Small size – 2 BRIC-Link IIs occupy 1U of rack space
  • Streaming server capabilities


Transmission Modes and Delay

BRIC-Link II is a true codec, offering a full-duplex stereo encoder and decoder in each box. The BRIC technology incorporated includes a jitter buffer manager that automatically balances delay and stability, dynamically increasing and decreasing delay based on network performance. End to end coding delay in linear modes is less than 25mS and FLAC modes are less than 30mS.


CrossLock technology employed by BRIC-Link II enables you to use multiple networks at once. By sending two identical streams through two separate networks, CrossLock provides a fail-safe in the event that the primary network falters. With seamless transition between the two audio paths, listeners will be none-the-wiser if one of your networks completely fails. With additional tools, such as forward error correction (FEC) and dynamic jitter buffer, CrossLock gives you confidence.

Audio Coding

For users concerned about delay and coding artifacts, BRIC-Link II offers a robust stereo or mono linear mode that does not compress audio. BRIC-Link II is also the only real-time audio codec to offer FLAC lossless compression. Additionally, BRIC-Link II offers AAC/HE-AAC modes as standard, along with Opus, and VoIP standards G.722 and G.711.

User Interface

BRIC-Link II acts as a web interface, allowing the user to access all controls through an intuitive web interface. The page displays connection status, extensive network diagnostics, and audio level meters for remote monitoring. From any location, users are able to configure profiles for various connections with point-and-click connection commands.

Streaming Server Mode

BRIC-Link II can function as a streaming server, delivering multiple streams to computer based media players that support HE-AAC – up to 40 streams over a T1 Internet connection at once. BRIC-Link II also offers the ability to act as a source feed for both SHOUTcast and Icecast servers – with a single BRIC-Link II, you can expand your radio presence to the Internet without the need for a dedicated PC.

App Compatibility

Both BRIC-Link II and BRIC-Link are compatible with smartphone applications, including Linphone and Luci Live. Connect to your codec from your smartphone quickly and easily for easy drop-ins and spontaneous remotes.

Codec Commander

Codec Commander is a Microsoft Windows™ application you can use to control your audio codec. You can manage your connections, check statistics, view audio metering, adjust audio profiles or change system settings.
