What is the X.Sum Mixer?

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 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.

The In's & Out's

All audio inputs and outputs are fully balanced and available on TRS connectors.

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.

What We Think

Speck is Vince Poulos, Vince Poulos is Speck…Vince cares about what he does and it’s reflected in the sound of his products. Having been in the audio mixer (and various other products) business for over 25 years, I guess you could say he just keeps getting better and better! The X Sum is a colorless box, meant to give back as clean a sound as you could want. With plenty of features for line level mixing and routing, and as a summing box…you can’t go wrong with the X Sum. With the addition of the breakout modules the possibilities for adding flavor on the output or greater routing capabilities are now yours!
