Stereo Master XLR Summing Mixer – 4 Ch Input XLR Summing Mixer – Desktop Analog Summing (Dual Stereo Balanced)

The unit delivers natural analog glue, depth, and punch — perfect for hybrid mixing workflows.
Pro Tip:
Push your instruments into the summing mixer at a higher level until you start hearing a subtle harmonic saturation. This adds warmth, dimension, and better separation — giving your mix that polished, record-ready feel. The generous headroom ensures your transients remain clean and dynamic.

little beast – glues my mixes like a dangerous and api box
didn’t expect this tiny unit to sound that good. super clean, open, and transparent — exactly what i wanted for summing my dangerous and api chains together. i went with the -6db silver wiring version, and man… it’s smooth, punchy, and totally noise-free. feels like a high-end analog glue box in a compact form. love it!

Perfect clean analog cumming solution
Exactly what I was hoping for — clean, transparent, and perfectly balanced sound. I went with the -6dB silver wiring version, and it works flawlessly. I’m using it to combine two summing mixers (Neve and SSL), and this little box does the job beautifully. The sound stays pure, open, and natural — no loss, just smooth analog glue.
