2 Dear Reader,

These are good times for Telos and Omnia. We get great satisfaction knowing that broadcasters in over 175 countries are using our gear everyday.

We’ve just celebrated the 10th anniversary of the Telos Zephyr family of codecs. With over 10,000 Zephyrs in use around the world, it is the most successful digital broadcast product ever.

More than half of the USA’s top 100 FM radio stations process with Omnia – as well as hundreds of major broadcasters such as the BBC, the NRJ Network, RTL Radio and the Korean Broadcasting System.

Our work has always involved audio and networks. Taking this to a higher level, we’ve just opened a new division and product family called Axia. These products bring the benefits of networking to the modern computer-centric radio studio.

Our goal from the very beginning has been to find new and better ways to do things. As should be clear after you browse this catalog, we’re not in the “me-too” business. Even after 20 years, we’re happiest when we are pioneering.

And each day we give thanks that you have placed your trust in us. We promise to keep earning it.

—Steve Church, Founder and CEO (on behalf of the amazing Telos/Omnia/Axia team who develop, build, sell, and support all the kool stuff!)

3 Axia: The Name Is As New As The Possibilities

Meet Axia, a new Telos company, focused audio signals over a CAT-5e wire from one on helping you build studio facilities to room to another. Insert some fiber in between, meet today’s most demanding broadcasting and go across campus. Attach a few more applications. Axia specializes in audio routing nodes and an Ethernet switch and you have a switchers, digital mixing/processing engines distributed multi-room routing switcher. Plug and control surfaces, as well as a wide range in a control surface and a mix engine and you of other devices used to distribute, mix, and have a powerful networked broadcast console. process audio within the broadcast plant - Now, plug your delivery system PC into that with a unique advantage: Every piece of Axia same Ethernet switch and you can transfer gear is fully networked, including the audio! files, live audio, and associated data - all over that same net. Axia offers a variety of Ethernet networked audio devices - think of these as “building Axia simplifies, saves you money, gives blocks” - that allow you to assemble different you choices, and prepares you for today’s applications for your radio studios.

You can transmit and receive 10,000 Zephyr codecs in radio two mono channels to and from stations and production studios separate locations, even transmit around the globe. Zephyr Xstream and decode streaming MP3 audio in your rack or remote kit gives you over Ethernet.

20 Flexible, Economical, Easy To Use There are three Zephyr Xstream models with capabilities tailored to fit your need, but all Zephyr Xstream models share these advanced features:

• MPEG2 AAC (Advanced Audio Coding). This new standard for audio coding permits true CD-quality stereo transmission with a connection speed of just 128 kbps. • Low-Delay MPEG4 AAC-LD coding. Using AAC- LD, you’ll enjoy crystal-clear audio quality with greatly reduced encoding delay for smooth, natural bidirectional remotes. • Works with companion Zephyr Xport portable codec to receive 15kHz audio using a POTS field connection. • V.35 option allows connection to serial synchronous data equipment for use with services such as dedicated lines, Switched 56, or Satellite services. • A unique Dual Receive mode in MPEG Layer 3 allows reception of independent audio streams arriving from two distant codecs – great for bilingual broadcasts. • Auto Receive mode searches and determines the correct decoder settings for the incoming audio stream. Zephyr Xstream allows you to transmit two-way 20kHz • Advanced technology with low heat generation stereo audio plus ancillary means no cooling fan for silent operation. data anywhere in the world using a single ISDN circuit, or 15 or 20kHz mono audio on a single ISDN “B” channel.
