E-DXE Audio Processor

24 frame I/O ports, up to a group total of 1536 inputs and 1536 outputs


A minimum of one  EDXE  frame is required for every DRS Series Enterprise System. A second EDXE  may be added to any group for full data stream redundancy.

Each EDXE  provides 24 I/O Ports for connection with audio signal frames, MADI adapters or Cheetah Mux/Demux video cards, up to a group total of 1536 inputs and 1536 outputs. EDXE frames are equipped with at least one PERC1000 Frame Controller device; a second frame controller may be added for control redundancy. A second power supply may be added to any EDXE frame for full power redundancy. The frame controller in each EDXE communicates over a 10/100 Ethernet link; adding a second frame controller creates an additional network device for control redundancy.


  • 24 frame I/O frame ports
  • Group total 1536 inputs and 1536 outputs
  • PERC controller with optional second frame controller for redundancy
  • Optional second power supply for redundancy
  • 10/100 Ethernet link

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.

Frame Controller Ethernet Port: There are two Frame Controller Ethernet Port Connectors (RJ-45) located on the rear panel of each DXE frame. These are located on the lower edge of each side of the frame rear panel, labeled ETHERNET CTRL “A” (the primary frame controller) and ETHERNET CTRL “B”.

I/O Frame Ports: There are 24 I/O Frame Port Connectors (RJ-45) located on the rear panel of every EDXE frame – positioned as two groups of 12 connectors each. These connector groups are labeled 1 thru 12 and 13 thru 24, and are used to interface the EDXE frame with up to 24 signal frames through the TDM bus.

EDXE Links: Located in the center of the rear panel are four fiber optic cable connectors denoted as EDXE Links. These connectors are labeled A thru D and are used to interconnect EDXE frames in expanded Enterprise DRS systems requiring more than one EDXE. All EDXE to EDXE connections are made using LC to LC duplex fiber optic cable.

Sync Reference Connectors: The EDXE rear panel contains a pair of BNC connectors, labeled SYNC, for attaching a sync reference signal source to the audio router. Either connector may be used for signal input, and the remaining connector used as a looping output for the signal if you wish to daisy-chain the signal source to other equipment.

Power Cord Connector Access: Access port for attaching power cord directly to power supply portion of controller module. Each power supply carries its own dedicated power receptacle. Input power is not bussed between modules. When two power supplies are used (for redundancy) a separate power cord must be attached to each receptacle through its access port. Each access port is equipped with a harness device for the input power cord. The harness secures the cord to help prevent accidentally disconnecting the frame from its power source.
