How can I connect a subwoofer to the EDGE W?

Although the EDGE W does not contain a dedicated subwoofer output, you can connect a subwoofer by connecting either of the unbalanced RCA Pre-Outputs to the corresponding inputs on the rear of your powered sub.

The sub's audio level will then follow the volume commands of the EDGE to ensure everything increases/decreases volume in sync.
