4-Channel XLR Summing Mixer with Volume Control – Mute & Mono Switch

Pro Tip: Push the instruments into the summing mixer at a higher level until you start hearing a subtle harmonic distortion. This will add warmth, depth, and better separation to your mix, giving it a more professional, polished sound—just like a finished record. The headroom provides a safe place for transients, ensuring clarity and punch in your mix.
