AES Vienna Video: Comrex Access Remote Broadcast Interface
Here's one for the broadcasters: The Comrex Access is a telephony interface for sending stereo audio to wherever you need it in the world via a telephone or other network. It aims to replace the commonly used ISDN lines for such work and move that audio using mysterious magic called IP - although you probably call it the Internet. The mobile unit is paired with a nifty six-channel mixer, making it a decent choice for classic remote broadcast applications from sports to news to various live events including - oh yeah - music. Check out the Access in this Gearwire video shot live from the floor of the 122nd Audio Engineering Society convention in Vienna Austria.
SPEAKER: Hello. I'm going to show you this is the Comrex, the new portable Comrex Access, which is an IP internet codec designed for sending audio over the public internet. It works on contended circuits so when Joe90 next door starts downloading his movies, it still works over the internet. It doesn't demand much of it.
It's compatible with other internet codecs and what you do, you simply select your address book here. We've got these various codecs on the internet, for example in London, in Boston, and we push connect, and we join up, we connect to it, and we've got 15 kHz stereo working on 3G, so then.

JASON DONNELLY: And what will be the application for a device like this?
SPEAKER: Okay. It's typically used for reporting, for going -- this is your radio car. This now your handheld radio car, and it will plug into a mixer, so here's the same codec, plugged into the mixer, and this provides you with six inputs so your host, your producer, your guest, second guest, and then an auxiliary channel that will give you a feedback, so if you're going to a shopping center, for example, that will give you the feedback from the studio. And because it's stereo, you've got talkback from the studio plus programmed sound from the studio and you can send clean feed and also commentary separately back to the studio, so typically used for football, for news reporting, and replaces the ISDN type portable codecs and PSDN codecs, which this is also compatible with. It also works on stereo POTS codec as well.
