Speck Electronics XSUM

Manufactured by: Speck Electronics

Mix it - Group it - Combine it - Blend it - Sum it
The X.Sum design takes you beyond the simple “hard-left” or “hard-right” summing box, and gives you 16 stereo input channels with level, pan, mix assign and mono select.
Closeup View
If you need more than simple summing, then you need the X.Sum.
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.
The In's & Out's
 Features
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.

Rear Closeup View
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.
Breakout Box Details
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.
