Why Use an Analog Summing Mixer?
Enhance your ITB mixes with subtle analog harmonic distortion, warmth, and depth. Push instruments slightly hotter into the summing mixer to add separation, clarity, and a polished, professional sound – just like a finished record. Headroom ensures transients are safe, keeping your mix clear and punchy.
