Vortex Access-R

The industry-standard ACCESS from Comrex is a true revolution in audio codecs. Developed from the ground up for use over the public internet, it provides 2-way, stable, stereo, low-delay audio over pretty much any type of internet connection, including wireless systems such as WiFi, 4G and 3G. A pair of rackmounts will provide a superb ISDN replacement whilst the portable unit effectively gives you a radio car in the palm of your hand! It literally is as good as it sounds and is being used by a huge number of broadcasters worldwide.

IP Networks

IP networks are available virtually everywhere. ACCESS Rack offers several ways to get connected. You can use the integrated Ethernet ports to connect to wired DSL or broadband cable IP networks. ACCESS Rack has a built-in POTS/PSTN modem for use on legacy analog phone lines.


CrossLock is the most advanced network management tool on the market today, CrossLock gives users the ability to manage and bond multiple data connections together simultaneously. When a new network is introduced, Crosslock will immediately evaluate how much bandwidth is available, while factoring in latency and jitter information, and combine the two connections to take advantage of all available bandwidth. More than just combining networks, CrossLock can also monitor each data connection individually and, when necessary, apply appropriate error correction, recovery, or concealment techniques.

User Interface

ACCESS Rack is controlled with an easy-to-use browser based interface. Using any Flash-enabled browser, you can log-in from anywhere to manage settings, adjust controls, and monitor connections.

MCC Multi-Codec Control

MCC is the BRIC IP Codec Management software that helps control, maintain and monitor your ACCESS, BRIC-Link or MIDAS codecs. Call/Drop function for remote use, Packet Loss, Delay, Call Quality and many other parameters to help keep your broadcast seamless and problem free with full control of your codecs from a single instance of Windows.

App Compatibility

ACCESS Rack is 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.
ACCESS Rack is also compatible with FieldTap. A free application for iOS and Android, FieldTap makes it simple to connect with the touch of a button. Plus, FieldTap is compatible with all other Comrex IP audio codecs.

Switchboard TS

Comrex Switchboard is a feature that allows users to bypass common IP networking snags (like private LANs and firewalls) by routing data through a private server maintained by Comrex.

Switchboard within the hardware codec enables the following functions:

  • Comrex audio codecs can sync with a cloud based server and deliver status information
  • Comrex audio codecs can determine their public IP address and the type of any NAT-style router ahead of the codec, and display that information to the user
  • Comrex audio codecs can display presence, status, NAT info and IP addresses of other codecs within the same fleet
  • Comrex audio codecs can share this information with codecs outside the fleet (Shares)
  • Comrex audio codecs can take instruction from the server on how best to traverse NATs when placing a call between two codecs

Switchboard TS is included in the purchase of any ACCESS codec.

Codec Commander

Codec Commander from Comrex is also available. Codec Commander provides the same control capability as the existing web interface, but doesn’t use Adobe Flash, making it a good alternative for users who are concerned about frequent updates and security risks.
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.
