The Telos Zephyr Xstream rackmount transceiver is specially designed to work with a single ISDN line or other low-bitrate transmission paths, including IP networks, so it's an ideal choice for broadcast or voiceover studios, permanent remote locations or wherever high-quality transmission of news, sports, music or production is needed.

With its two-channel flexibility over a single ISDN circuit (or two synchronous links), Zephyr Xstream can transmit and receive 20kHz stereo audio to and from a single location, or two mono channels to and from separate locations.

Zephyr Xstream also offers IP streaming with both MP3 and AAC. Its AAC decoder incorporates error concealment.

Note: Audio codec systems require two units for operation.
