Enterprise Audio Systems up to 7680x7680

Designed specifically for large venue environments

DRS - Enterprise Audio Systems


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 (EDXE) chassis that connects up to 24 independent audio I/O frames which can be stacked to serve as a centralized system; or each  EDXE frame can be independently located at the source several miles away by using fiber optic cabling interconnects. Each audio I/O frame supports up to 128 inputs or outputs for a total of 1536 X 1536 with one EDXE  By adding additional EDXE  units, systems can be populated up to 7680 X 7680 using five EDXE  frames .

The Enterprise DRS allows users to integrate AES/EBU, Analog Audio, MADI and Time Code – all within one distributed system.


  • AES, analog, MADI, and time code in one common package
  • 1RU supports 128 channels per audio I/O frame
  • Select from BNC, ELCO, or 6-pin pluggable connectors
  • Build systems that support I/O capacity up to 7680x7680
  • Connect up to 24 audio I/O frames per EDXE
  • Support I/O capacity up to 1536x1536 using just one EDXE frame

The Cheetah router can be integrated with the DRS Audio system allowing users the flexibility to route embedded AES or discrete audio with any SDI/HD-SDI video stream. With the DRS compact audio router system and Cheetah MUX/DEMUX modules, users have the ability to reduce overall cost and power consumption. With DRS integrated audio modules, any audio input can be embedded to any video output.
