Speck Electronics X.Sum Mixer Description
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.
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
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.
The Designer
The X.Sum
is the work of Vince Poulos, the designer and owner of Speck Electronics.
