CrossLock

Quite simply 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. CrossLock can also work in redundancy mode in where it sends two identical streams over each network.

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 codecs can sync with a cloud based server and deliver status information
  • Comrex 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 codecs can display presence, status, NAT info and IP addresses of other codecs within the same fleet
  • Comrex codecs can share this information with codecs outside the fleet (Shares)
  • Comrex 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.

Configuration & Control

MultiRack is controlled with an easy-to-use browser based interface. Using any HTML5-enabled browser, you can log-in from anywhere to manage settings, adjust controls, and monitor connections. 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.

In addition to the web GUI, Codec Commander is a Windows-based application you can use to control your audio codec. You can manage connections, check statistics, view audio metering, adjust audio profiles or change system settings.

Codec Commander is free to download and use. For controlling multiple Comrex IP audio codecs once, check out Fleet Commander (paid upgrade).

App Compatibility

ACCESS is compatible with smartphone applications, including Linphone and Luci Live. Connect to ACCESS from your smartphone quickly and easily for easy drop-ins and spontaneous remotes.

ACCESS 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.

HotSwap for Cellular Backup

HotSwap allows users to back up studio-to-transmitter links (STL) or other dedicated links with a wireless modem. For ACCESS codecs like MultiRack, any supported modem can be used as a back-up.

HotSwap lets users select a network that will only be engaged if the primary network fails. The system will warn of this status with a contact closure, and automatically fallback to the primary once it’s restored. Fall-over to backup happens in a matter of seconds, and fallback is seamless.

HotSwap is included in firmware v4.3 and higher. Visit the MultiRack support page for current firmware. Contact the techies with any questions.

Accessories

NEW! Gagl

Gagl is a great way to get guests on the air from anywhere, easily.

More on Gagl

Gagl is now available! Sign up directly on our website by visiting the Gagl web page.

Gagl subscriptions are $35.00 USD per month (or save $70.00 on a Gagl annual subscription with a code from a Comrex audio dealer or from us directly).

Free 14-day trial available with all new subscriptions.

Fleet Commander

Fleet Commander is a Windows-based application for controlling multiple Comrex IP audio codecs simultaneously. Rather than logging into each codec individually and juggling a desktop full of tabs, Fleet Commander puts you in control of your codec fleet through one unified interface.

This easy-to-use tool contains all of the functionality of the web-based interface plus a few extra features like active metering and the ability to copy peers and profiles between codecs, making it a MUST-have for busy broadcast engineers.

More on Fleet Commander

Fleet Commander is available as a one-time purchase of a license key per computer. Contact a Comrex audio dealer to purchase a Fleet Commander license today.

Comrex Connect Modems

The Comrex Connect Modem is designed to support the unique needs of remote broadcasters. A high-powered, industrial strength 4G/LTE modem outfitted with a high-gain antenna, the Connect Modem is more powerful than most USB data modems available on the market, to handle the heavy data load of IP broadcast.

Learn more about Comrex Connect Modems

Contact a Comrex audio dealer to purchase a Connect Modem and be sure to specify which variety: US (for use with Verizon or AT&T networks), International (for use outside the US) or CJ (for use in China, Japan, Taiwan, Korea & Brazil). No Connect Modem mounting hardware needed for use with ACCESS MultiRack.

A note about contact closures & serial data

ACCESS MultiRack includes connectors on the back to supply contact closure and serial data to the first codec instance only. In order to deliver contact closures and serial data for codec instances 2-5, an accessory is required, and found here (for contact closures) and here (for serial data).

Please note that we do NOT sell these accessories directly. You can purchase them from retailers like Digikey, Newegg, Amazon, Mouser, etc.
