32x32 AES & MADI Router/Interface

Product ManualManual
  • VistaLINK® enabled

The 7800EMR-IO is a compact audio router/interface module that can be configured to operate in a number of modes depending on the application requirements. One mode as a fully functional standalone router with AES and MADI I/O another mode will allow the module to act as a input / output interface that can be used to connect to a ADMX crosspoint for integration into a Evertz modular EMR audio router. Further details and diagrams for both of the Standalone Router Mode and the ADMX I/O mode can be found in the Features and Benefits section.

Having multiple modes allows for future growth from the stand alone router into a modular EMR-Audio system, or even can be used to expand a existing EMR-Audio router.

Each module contains 32 unbalanced AES inputs and 32 unbalanced AES outputs using DIN connectors as well as 2 MADI Input and 2 MADI output ports, all these are used in both modes. There is an additional 2 input and 2 additional output ports that are software programmable to be MADI or TDM for the different modes.


Standalone Router Mode

This provides a 32x32 AES router (64x64 mono) plus 4 MADI inputs and 4 MADI outputs, giving a total of 320 mono I/O channels

Key Features

  • Mono routing
  • The synchronous Crosspoint only handles streams locked to the reference or the sample rate converted stream
  • AES SRC conversion with auto bypass for encoded streams
  • Crosspoint with processor block providing:
  • Cross fader for soft-switching PCM streams with auto bypass
  • 4:1 Mixer
  • Gain control
  • Mute
  • Phase inversion
  • Delay Option
  • Audio Monitoring
  • Adjustable Tone Generator


This provides a 32x32 AES that is used in conjunction with an EMR ADMX Crosspoint. It provides 32 AES input plus 2 MADI inputs to the ADMX, and 32 AES plus 2 MADI outputs from the ADMX, giving a total of 192 mono I/O channels.

Key Features

  • Dual TDM inputs with auto swap
  • Dual TDM outputs for redundant ADMX connection
  • AES SRC conversion with auto bypass for encoded streams
  • Input processor block providing :
  • 4:1 Mixer
  • Gain control
