The multi-bus compression sub-group passive summing technique is a game-changer for mixing engineers. The ability to process different elements of a mix separately and then sum them back together allows for greater control over the final sound.

The fixed sub mixers with dedicated inputs and individual send/return for external processing make it easy to integrate this technique into any mixing setup. Overall, this is a highly effective and efficient way to achieve a tighter, more professional-sounding mix.
