Comrex Version Security Concerns and Firmware Fixes



NEW! Gagl

The perfect way to get more out of your codec. 

Gagl is a cloud-based remote contribution service that allows up to five users to send and receive audio from their smartphones or laptops. That audio is Gagl’d (if more than one user) and delivered to a Comrex IP codec (like ACCESS Rack). 

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

Learn more about 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 software 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. With the ability to manage all codecs from one simple window, this easy-to-use tool can save time and increase productivity for busy engineers.

Fleet Commander contains all of the functionality of the Web-based Interface, but also comes with a few more features like active metering and the ability to copy peers and profiles between codecs. A Windows application, Fleet Commander can be used to manage every Comrex IP Audio codec in your fleet (depending on CPU and network limitations).


  • Simple to use
  • Unified interface for multiple codec management
  • Compatible with Windows 7, 8, and 10

Learn more about Fleet Commander

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

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 a broadcast over IP.

Please note: FW 4.5p6 or higher is required on ACCESS Rack to use the US Connect Modem. 

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 United States) or CJ (for use in China, Japan, Taiwan, Korea, and Brazil). No Connect Modem mounting hardware needed.
