Active Summing Mixers with Legendary NOS Transformer Amplifiers

Hand-built in the EU · Neumann · Filtek · Lawo · Custom-Calibrated

Unique 2-in-1 Technology

On request, every unit can be built with an Active/Passive dual-function option — switching between ultra-transparent passive summing and transformer-driven active mode with harmonic character and controlled gain recovery.

VintageMaker active summing mixers aren't just signal combiners — they're hybrid analog summing weapons for DAW professionals, delivering transformer-driven depth for music production, mixing and mastering.

The Sound of Heritage: Neumann, Filtek & Lawo NOS Transformers

Our active transformer summing mixers are built around rare, iconic New Old Stock (NOS) transformers sourced from the golden era of German vintage mixing console professional broadcast engineering. Each transformer series delivers a distinct, studio-proven sonic signature impossible to replicate in software:

Neumann V475 Series German Broadcast Legend

The absolute legend of analog summing. The Neumann V475 delivers massive headroom, a wide 3D stereo image, and that elusive "analog glue" that brings a mix together with warmth and dimension.
