<h3>X.Sum Ins & Outs</h3>
	Connect the X.Sum to virtually any line level source: balanced, unbalanced, transformer, or transformer-less. The  X.Sum has high headroom that will handle balanced signals up to +28dBu. All audio inputs and outputs are fully balanced and available on TRS connectors.
<br /><br />
Looking a bit closer at the rear panel, you will notice a Multi-function I/O connector. This connection increases the functionailty of the X.Sum's inputs and outputs.<br /><br />
The X.Sum includes an external breakout box that adds connectors for the Mix-B outputs and "Pre" Mix-A outputs. The left/right "Pre" Mix-A outputs bypass the X.Sum's master section so you can use your own external preamps to add character and color to your mix.<br /><br />
