  • Page 4 Dante products, this is further expandable with AES67 compatibility. With 64 channels per MADI Bridge (at 48kHz) and up to 512 channels per 1Gb network link, Dante is fully scalable and capable of providing routing channel counts from tens to thousands and beyond using standard IT infrastructure.
  • Page 5 MADI Bridge User Guide Contents Virtual Headphone Patch    Monitoring and signal present metering is provided for incoming and outgoing MADI and Dante ports. It replaces patchbay based routing with a digital network whilst retaining confidence and fault finding tools.
  • Page 6 MADI Connectivity for a System T Network  This provides MADI connectivity available to all networked System T consoles. The MADI Bridge can also be used as a clock master for the Dante network or to provide external TDM devices with a clock source.
  • Page 7 MADI Bridge User Guide Contents Building a Distributed and Expandable MADI Router    Redundant or Split Mode MADI  The secondary MADI input can be used as a redundant backup of the primary input, or as a second MADI input when in Split Mode. Here the MADI channel allocation is divided between the ports, dependant on the MADI and Dante sample rates.

  • Page 8: Hardware Connections

    MADI Bridge has two redundant sets of network connections. Note: Some Dante devices allow Dante ports to be set to Switched mode rather than Redundant mode. MADI Bridge uses the extension ports to provide this functionality, without loss of redundancy.
  • Page 9 MADI Bridge User Guide Contents Clock  CLOCK for setup details and Clocking Scenarios for additional information. GPIO  4 General Purpose opto-coupled inputs and 4 General Purpose relay outputs allow embedding and de-embedding of logic signals across the network. Appendix D for pinout information.

    Note that the Monitor ( MON ) menu remains accessible even whilst in front panel lockout. N.B. Holding both the LOCK and Z buttons together for 3 seconds restarts the MADI Bridge. The default Info page shows the following information:...
  • Page 11 MADI Bridge User Guide Contents Turning the SELECT encoder scrolls through the info pages: MON  Pressing the MON button brings up the Monitor menu or Channel Name page. Press the MON button again to navigate between these pages. The chosen page will be remembered when navigating to the MON page in future.

    MADI Bridge User Guide Contents REDU  The REDU (Redundancy) menu allows you to set up the MADI redundancy options when interfacing various MADI devices. In addition, it provides fault-finding tools to continuity-check the validity of MADI signals directly from the front panel, or instigate Forced Override should you need to override the automatic redundancy mode.

    N.B. With SRC on, the clocking options do not include Dante. Dante clocking is determined in Dante Controller. The CLOCK LED will flash if the MADI Bridge has swapped over to the secondary clock. A manual detection of the primary clock is needed to force it to the primary clock.

    With the focus box on Dante Info the encoder has no function, Dante Info reports the Dante sample rate set for the MADI Bridge from Dante Controller. The SRATE LED will flash if the sample rates do not match and SRC is switched off.

  • Page 17: Mode

    N.B. On older design MADI Bridge devices the MODE button is labelled U . To enable the pass-through of AES user and control bits the MADI Bridge must be set to PCM 32 encoding within Dante Controller. Changing the encoding setting is detailed in the Dante Controller section of this guide.

    MADI Bridge User Guide Contents Dante Controller  Refer to Audinate’s Dante Controller user guide for complete information on Dante Controller software. The information below details the basics required to get started. Clock sync, device naming and network management are all done within Dante Controller.

  • Page 19: User And Control Bit Pass-Through

    MADI Bridge User Guide Contents User and Control Bit Pass-Through    To enable the pass-through of AES user and control bits the device must be set to 32-bit encoding ( PCM 32 ). This is set within the Encoding section of the Device Config tab.

    ‘Enable sync to external’ within Dante Controller. This provides the network with redundant master clock sources referenced to the house synchronisation. One device would be elected as the Grand Master Clock for the Dante network, if that were to fail another MADI Bridge would take the role of Grand Master.
