Application Note

System Design

It has never been so easy to design a bespoke high performance AVOIP system. No source and zone restrictions or limitations.

Redefined Signal Flow

Picture Picture

Conclusions

  • Signal flow is highly simplified. Channels can be fed into the network from anywhere and also taken from wherever they are needed.
  • Once a limiting matrix is lacking, the number of sources and destinations can be scaled as you ever dreamed of.
  • Get rid or channel limitationd on DSP’s matrixes.

Symetrix Symnet Integration

SDM can eavesdrop on communications with Symetrix Symnet devices and act on commands accordingly Together with predefined sources and destinations in configuration files, simple control numbers are used to select sources

Sources

  • Defined in config file symnet_config_sources.toml on SDM
  • Each value of a control number can be assigned to a source with an unlimited number of channels
  • For each source a delay can be defined which is applied before switching over

Destinations

  • Defined in config file symnet_config_destinations.toml on SDM
  • Each control number can be assigned to a destination with an unlimited number of channels
  • For each destination a delay can be defined which is applied before switching off
  • A feed back control number can notify the attached control system once a switchover or switch off executed successfully
  • Several Symetrix DSPs can be monitored, in extreme cases individually for each control number

How does it work?

Lets take as example that we are connected to a DSP and listen on control number 5001

  1. Once the control number 5001 appears SDM looks up in symnet_config_destinations and finds 5001 as the destination “Lounge”
  2. The value we received is 10, SDM looks up in symnet_config_sources and finds the value as defined for source “Radio”
  3. SDM now reads all channels for “Lounge”, finds the receiver for them and gives it the instruction to receive the source channels from “Radio”
  4. When the recipient has confirmed receipt, SDM sends back confirmation of the transaction to Symetrix
