Comrex ACCESS MultiRack

A rackmount IP audio multi-codec, capable of five full-duplex IP audio codec connections

For users who need to run multiple IP codecs at once, Comrex has created ACCESS MultiRack. ACCESS MultiRack is equivalent to five codecs, contained within a sleek 1RU chassis.

Exceptional CrossLock VPN Technology

When used in “bonding” mode, 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. In Redundant mode, all data will be sent over all networks.

CrossLock also monitors each data connection individually and applies appropriate error correction, recovery, or concealment techniques as needed. It’s quite simply the most advanced network management tool on the market today.

Switchboard TS for NAT Traversal

Comrex Switchboard was created to make it easy to make connections between Comrex IP codecs. This is especially important when broadcasting over networks that have firewalls and routers and other IT snags. Switchboard allows your codec to sync with a cloud-based server, making it possible to connect without having to know the IP addresses on either end of the link.

Switchboard saves all the details of the codecs subscribed to the server so that, when it’s time to connect, you don’t have to enter any information – you can just choose the codec you want to connect to from a menu and hit a button.

Switchboard is included in the purchase of any Comrex ACCESS IP audio codec.

Configuration & Control

NX Rack 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).

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 NX Rack, 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 NX Rack support page for current firmware. Contact the techies with any questions.

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.
