Section 2: INTRODUCTION – Getting to Know the Zephyr Xstream 16
2.2 Why the Zephyr Xstream?
Zephyr Xstream is the logical “next step” to our highly successful Zephyr and ZephyrExpress
products. We’ve taken the latest technology, years of experience, and suggestions from users
like yourself, to create these new products.
You and your staff will benefit from the fact that the three models of the Xstream are identical
in their operation. Only the audio menu differs between the mixer and non‐mixer versions.
ISDN stands for Integrated Services Digital Network. Xstream is the only codec that takes full
advantage of its integration, offering connectivity to telephones, the Xport POTS codec, as well
as ISDN codecs. You save on board/router inputs. Operators need learn only one box. And,
there is no need for another line at the studio, one ISDN line meets all your needs.
ISDN to POTS technology is undeniably superior for modem performance vs POTS to POTS, and
is exactly how Internet Service Provider's provide "56 K" modem connections. To describe this
succinctly, this arrangement is better because there is 50% less "POTS," and 50% more digital,
transmission (in the majority of cases) vs the POTS to POTS connection used by other
manufacturer's equipment. For more on the various types of connections possible with your
Xstream, see Section 10 (Applications Guide) where we illustrate them.
No other broadcast codec offers the flexibility and power available in the Zephyr Xstream family.
2.3 Xstream vs. Xstream MX vs. Xstream MXP
Zephyr Xstream
This is the basic model and will usually find its home in the studio. Highlights of the Zephyr
Xstream are:
• Supports the MPEG AAC, Layer‐2, Layer‐3 and G.722 coding standards.
• MPEG AAC‐LD offers Layer‐3 fidelity with 75% less delay.
• AES/EBU inputs and outputs (standard)
• Analog line level inputs and outputs (Switchable between “Consumer” and
“Professional” Levels)
• Short learning curve. Zephyr users will be up and running in minutes.
• High reliability design. No fan or battery to fail. Rugged chassis design.
Zephyr Xstream MX and MXP
These are typically found in remote facilities. These two units are identical with the exception
that the MX is rack mountable whereas the MXP has a portable chassis. Highlights of the Zephyr
Xstream MX & MXP are:
• Supports the MPEG2 AAC, Layer‐2, Layer‐3 and G.722 coding standards.
• Exclusive MPEG4 AAC‐LD offer Layer‐3 fidelity with 75% less delay.
• Short learning curve. Zephyr users will be up and running in minutes.
