and unbalanced signals.

just one of the audio sources using the Admin panel.

Configure audio ports for stereo or mono
The four XLR professional line-level inputs are configured as two stereo pairs by default: XLR A (left and right

Using the Admin panel, you can configure these ports to function as a stereo pair (left/right) or as separate 
mono ports.
