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.
