Telos ProSTREAM eliminates PCs for web audio streaming 
Compact 1RU appliance frees broadcasters from sound card, computer hassles

Broadcasters have been saying some very nice things about ProSTREAM, the new hardware streaming audio encoder from Telos. And why not? Since radio stations first began streaming audio to the Internet, they've wanted to be free of reliance on error-prone PCs with noisy consumer sound cards. Traditional streaming solutions demanded one computer to process audio, a second to encode it, and a third to stream it. Telos ProSTREAM gives broadcasters the freedom they've craved by integrating all of these functions in a single streaming appliance.

"The Telos ProSTREAM is a perfect set-and-forget appliance to bridge your live audio to the Internet," says Matt Rockwell, Chief Engineer at the University of Wisconsin, Madison's WSUM-FM. "ProSTREAM does a fantastic job of getting audio ready for the Internet. It really sounds great! ProSTREAM delivers a lot of service and convenience in a small package."

ProSTREAM converts your programming to superbly detailed streaming audio, optimized for any bit rate you select. A full three-band audio processor by Omnia Audio feeds an encoder section with genuine MPEG encoding algorithms from Fraunhofer, the inventors of MP3. The two sections are closely coupled; Omnia's unique SENSUS technology actually works with the encoder to analyze and adapt the processor's algorithms to the specific bit rate chosen so that the resulting sound is clean, powerful and artifact-free.

Finally, ProSTREAM sends its encoded audio - with your choice of MP3, AAC-LC or HE-AAC encoding - directly to a specified stream replicator for distribution to Internet listeners. You can feed ICEcast or any SHOUTcast or SHOUTcast-compatible media server, Wowza or Adobe Flash Media servers for streaming to Flash clients, and other popular third-party servers.

ProSTREAM can accommodate analog or Livewire IP-Audio audio input. Two separate Ethernet ports let you keep your house network safely separate from the outside world: the LAN port for audio input and browser-based remote control, and the WAN port for sending encoded audio to your streaming service provider. An intuitive Web interface makes setup a breeze; simple front-panel controls with adjacent headphone jack make for convenient on- the-fly adjustments, even in noisy rack rooms. The Omnia audio processing comes with a variety of presets designed to get you running quickly, while an easy-to-use preset editor gives you the power to create and fine-tune custom settings.

Best of all, ProSTREAM is neatly self-contained in a 1RU box. Just slide it into a rack and it’s ready to go. ProSTREAM carries a list price of $1,995 USD.
