Zephyr Xstream is the world’s leading ISDN codec, compatible with the widest variety of third party codecs. Coding choices include MPEG4-AAC and AAC-LD, Layer 2, Layer 3 & G.722 coding for full-duplex stereo operation of up to 20 kHz audio on a single ISDN line; broadcast quality mono audio at 15 kHz or 20 kHz is possible on a single ISDN “B” channel or other 56/64 kbps channel. All Xstream models feature professional balanced analog inputs/outputs, as well as Livewire® I/O for quick connection to Axia® networks; AES/EBU I/O is standard on rackmount model. An ISDN TA with integral NT1 provides worldwide ISDN compatibility without software changes. Remote Control is possible over RS-232 or Ethernet. Available in rack-mount version and portable version which incorporates a 4-channel stereo DSP mixer with selectable digital processing by Omnia®.

 

  • 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.

  • Low-Delay MPEG AAC-LD coding delivers crystal-clear audio quality and greatly reduced encoding delay for smooth, natural bi-directional remotes.

  • MPEG Layer-3 coding for compatibility with the largest number of third-party codecs. When using MPEG Layer-3, a unique Dual Receive mode allows reception of independent audio streams arriving from two distant ISDN lines – great for bilingual broadcasts.

  • Exclusive Error Concealment technology prevents occasional network glitches from being heard.

  • 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 placement of standard G.711 phone calls from your Zephyr Xstream.
