Why Choose a Passive Analog Summing Mixer?

Passive summing is the preferred method for engineers who want the warmth and depth of analog signal combining without the noise floor introduced by active circuitry. By routing your DAW outputs through a dedicated summing mixer, you gain a wider, more three-dimensional stereo image that in-the-box mixing simply can’t replicate.
