Active Matrix Surround Decoder

Use the Active Matrix Surround Decoder to create a 4 channel output with Center and Surround for use with Lt / Rt encoded stereo surround content.

In this example, an Active Matrix Surround Decoder is outputting the Lt / Rt / Center / Surround channels into the Amplifiers.

Tip: From top to bottom, the Active Matrix Surround Decoder reads: Left, Right, Center, Surround.

Tip: For additional properties not listed, refer to the Properties Panel help topic for more information.

Status

Component status is conveyed with the Status LED and Status box, which uses both color and text to indicate the current condition:

  • OK: The device is functioning normally.
  • Initializing: The device is in the process of a firmware or configuration update, or the design is starting.
  • Compromised: The device is functioning, but a non-fatal problem exists. Refer to the Status box for details.
  • Missing: The device cannot be discovered.
  • Fault: The device is malfunctioning or is not properly configured. Refer to the Status box for details.
  • Unknown: This status appears during a Core reboot (for example, during a firmware update), or when a design is being uploaded to the Core and before it has started running.
  • Not Present: If applicable to the device, this status appears when the device is not connected to the network and its Is Required component property is set to 'No'. This status also appears if the device component's Dynamically Paired property is set to 'Yes', pairing has not been assigned in Core Manager, and the device component's Is Required property is set to 'Yes'. See Dynamic Pairing.
