How to set up Symphony I/O MkII for Surround Monitoring (5.1, 7.1, 9.1, 11.1)

How to connect and configure a Surround Speaker Setup


When using Symphony with a surround speaker setup, the first set of outputs can be configured as speaker outputs suitable for connection to a 5.1, 7.1, 9.1, or 11.1 speaker system, depending on the analog outputs you have available. With this configuration, turning the Output Controller knob (or adjusting output from the keyboard, Symphony Control software, or optional Apogee Control Hardware Remote) will adjust all applicable line-outputs simultaneously.


Connect your speakers to Symphony’s analog outputs. A standard 5.1 surround setup is routed as follows:

  • Output 1: Front Left
  • Output 2: Front Right
  • Output 3: Center
  • Output 4: Sub-woofer
  • Output 5: Left Surround
  • Output 6: Right Surround


Open the Symphony Control app and click the Device button to reveal the Device Sidebar. The button looks like this:


From the Main Output Format drop-down box in the Device Sidebar, select your desired surround configuration:



  • Requires at least 8 analog outputs for the 7.1 option to become available
  • Requires at least 10 analog outputs for the 9.1 option to become available
  • Requires at least 12 analog outputs for the 11.1 option to become available
