    Sub Group passive summing for MultiBus Compression technique

    Based on the customers feedback, this is the best bus mixing technique there is. With a little practice and experience, your mixes will sound tighter, more energetic, more professional.

    Fixed sub mixers (slave sum AB) with dedicated inputs, each sub mixer (slave sum) group come with individual send/return for external process – then return to Master for final summing see documentation…..
