MODEL LP1200E

Multi-channel Fiber Optic Serial Digital Audio (AES/EBU) Transport Systems

DESCRIPTION

Model LT1200E The 1200E Series is a high performance, yet affordable, Fiber Optic Serial Digital Audio Transport System. The standard 1200E system is designed to transport four (4) or eight (8) channel AES/EBU serial digital audio signals over long distance through either singlemode or multimode fiber. The 1200E design accepts synchronous or asynchronous AES/EBU channels of 44.1 or 48 kHz frequency and many versions of optical transmitter and receiver combinations are available to address different distance requirements.

Because of the use of advanced digital fiber optic transmission technology, no user adjustments are required in the 1200E system, enabling quick setup and trouble-free operation. The 1200E is designed for compliance with AES3-1992 (ANSI S4.40-1992, IEC 958), a standard format and protocol for serial transmission of digital audio.

The 1200E comes with two packaging options: a rugged, standalone, and compact unit, or a plug-in card for a card cage system. Panel connectors are provided for digital serial audio (terminal block connector) and fiber connection (FC-type for the single modeversion, or ST-type for the multimode version). The 1200E can be easily monitored by front panel LED indicators for power, optical link, and channel activity.

The 1200E design is capable of addressing a variety of non-standard configurations. Contact us to discuss your custom, OEM/private brand and high volume requirements.
