Enterprise audio systems up to 7680 x 7680 using E-DXE processor. Designed specifically for large venue environments, the PESA Enterprise Audio Routing System provides a “unified” solution for audio and time code applications. At the heart of each distributed audio system is a 1RU Enterprise Data Exchange Engine (E-DXE) chassis that connects up to 24 independent I/O frames which can be stacked to serve as a centralized system; or each I/O frame can be independently located at the source several miles away by using fiber optic cabling interconnects. Each I/O frame supports up to 128 inputs or outputs for a total of 1536 X 1536 with one E-DXE. By adding additional E-DXE units, systems can be populated up to 7680 X 7680 using five DXE chassis. The Cheetah Enterprise DRS allows users to integrate AES/EBU, Analog Audio, MADI and Time Code – all within one distributed system.
