SUMBOX 1602MS

Analog Summing for your DAW

Professional themes

 The SUMBOX is not a transparent unit it adds saturation to your mix.  It's effect can be subtle, but when driven adds depth, and dimension to your recordings.  

16 Inputs

The SUMBOX 1602MS features 16 Analog Inputs on 2 DB-25 connectors.  

2 Pairs of Outputs

The output is split into 2 pairs of outputs.  This creates the ability to apply parallel processing to the mixed signal, or have a dedicated monitoring path.   

Few Controls by Design

The only controls on the unit are the Mono/Stereo selection swtiches.  The first 8 inputs are Mono/Stereo assignable via the push button switches.  The remaining 8 are assigned to 4 Stereo Pairs.  This aids in recall as all volume and mix decisions are made in the DAW.
