Description

The Best Way to Hear from There.

The Telos Zephyr is the best-loved broadcast codec in the world, and for good reason: Zephyr saves you time and money. A Zephyr Xstream at your studio becomes a “universal codec,” connecting with every popular ISDN codec for full-duplex, 20kHz stereo audio. Using ISDN you can transmit and receive two mono channels to and from separate locations, even transmit and decode streaming AAC and MP3 audio over Ethernet. And in the field, Zephyr Xstream is a powerful remote tool, with intuitive step-by-step operation, context sensitive help, and a simple user interface that eases operation for non-technical personnel. Zephyr pioneered the concept of the ISDN codec — which is why you’ll find more
Zephyrs in studios and remote kits around the world than any other codec.

Zephyr Xstream has a huge range of standard MPEG coding options, which include MPEG Layer-3 and MPEG AAC for indistinguishable source-from-input audio at only 128 kbps. Zephyr Xstream can also be used for LAN and WAN IP streaming of MP3 or AAC over properly managed networks. Zephyr’s AAC coding includes error concealment to inaudibly recover from a lost packet or two, and an adjustable packet jitter buffer allows you to easily accommodate different networks.

There are two Zephyr Xstream models tailored to fit your needs: The standard rack-mount Xstream, and the portable Xstream MXP, a ruggedized portable version with built-in DSP mixer and Phantom microphone power to help reduce field equipment inventory and setup times. All have standard Analog and Livewire I/O, and a built-in terminal adapter with integral NT1 for worldwide compatibility without software changes. The studio version also has standard AES/EBU I/O, and the portable XStream features a DSP-based AGC/limiter with Omnia audio processing and selectable presets for music & voice.

The Zephyr Xstream rackmount version is a full-featured ISDN transceiver with high-fidelity MPEG-2 AAC and lowdelay MPEG4 AAC-LD coding, along with standard Layer 3, Layer 2 and G.722. It includes AES/EBU I/O and features full duplex stereo operation of up to 20kHz audio on a single ISDN line; broadcast quality mono audio at 15kHz or 20kHz is possible on a single ISDN “B” channel or other 56/64 kbps channel. The front panel includes a backlit display screen with a friendly, logical control structure and Fast Access Menu Keys to quickly call up system information and settings. Other controls: send and receive metering, a dialing keypad, front-panel headphone jack with level control, and Auto-Dial of up to 100 stored Preset Numbers, each with its own bitrate and transmit/receive settings. 30 Location settings permit quick recall of ISDN line and audio settings for your most commonly visited sites.

Zephyr Xstream rear panelOn the rear panel you’ll find standard balanced analog I/O with auxiliary unbalanced inputs on the combination XLR/TRS connections. AES/EBU I/O is standard, with a separate AES sync inpurt. Remote control is supported via a Web browser interface using the 100 Base-T Ethernet port or RS-232 port. There are also eight bi-directional inputs/outputs for end-to-end contact closure emulation.. A built-in ISDN Terminal Adapter is compatible with telcos worldwide. Zephyr Xstream also has native Livewire support for one-cable connection to Axia AoIP networks.

The portable Zephyr Xstream MXP includes all the features of the Zephyr Xstream, plus a digital four-channel stereo mixer with two local mixes into a road-ready case for on-the-go broadcasting. The rugged shock-resistant case helps prevent bumps and bruisees, and an included flip-up metal stand tilts the unit up for the best viewing angle on desktops or whatever handy surface you’re broadcasting from. The alpha-numeric dial pad also generates DTMF tones for navigation through voice menu systems.

The four-input stereo DSP mixer directly feeds the codec section; mic/line switchable inputs with pan include a preset mic limiter & AGC processing by Omnia; inputs 1 & 2 also have switchable 48-volt Phantom power. There’s a front panel headphone jack for Local Mix 1 that monitors Send or Receive audio, or a mixture of the two. Local Mix 2 has separate front-panel controls for the three rear-panel headphone jacks, plust a pair of balanced XLR line outputs to feed guest phones or monitors.

Around back, the Xstream Portable differs from the rackmount Xstream by its inclusion of 4 input connections plus headphone/monitor outputs. Both Zephyr Xstream models are fan-free for silent operation.

Zephyr Xstream Specs At A Glance

Ethernet ports for remote control via LAN or WAN, and for connection to your Livewire AoIP networks. Bring audio from any codec anywhere in the world directly to your Axia network.
Auto Receive mode quickly determines the correct coding algorithm for incoming audio streams.
MPEG AAC (Advanced Audio Coding) permits true CD-quality stereo transmission with a connection speed of just 128 kbps. Exclusive Error Concealment technology prevents occasional network glitches from being heard.
Low-Delay MPEG AAC-LD coding: crystal-clear audio quality and greatly reduced encoding delay for smooth, natural bidirectional remotes.
MPEG Layer-3 coding for compatibility with the largest number of third-party codecs.
Unique Dual Receive mode when using MPEG Layer-3 allows reception of independent audio streams arriving from two distant ISDN lines – great for bilingual broadcasts.
RS-232 and 8-input, 8-output parallel ports provide ancillary data and bi-directional contact closures.
Hand-in-glove operation with companion Zephyr Xport portable codec for reception of 15kHz audio using a POTS field connection.
V.35/X21 option allows connection to serial synchronous data equipment, for use with dedicated lines, Switched 56 circuits or satellite services.
N/ACIP compliant for compatibility with the widest range of ISDN codecs.
Convenient ISDN Voice Telephone Mode allows standard G.711 phone calls right from your Zephyr Xstream
