Manufacturer's Description from Speck

The X.Sum is a 32 x 4 line mixer that can be used for external DAW summing or as a line mixer for synths, samplers, and effect returns. Any of the 16 stereo channels can be assigned to either the main stereo Mix output or the stereo Mix-B output.

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.

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.

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.
