6-Channel Passive Analog Studio Summing Mixer – 6 In / 2 Out Balanced Stereo Summing Box

6×2 TRS – XLR Passive Analog Studio Summing Mixer

Bring your digital mixes into the analog world.

AVAILABLE WITH TRS, XLR OR DB25 I/O – ASK!

The Vintage Maker 6×2 Passive Analog Summing Mixer is designed for engineers and producers who want greater depth, punch, stereo imaging and headroom than traditional in-the-box mixing.

Instead of summing audio mathematically inside your DAW, six balanced analog channels are combined through a carefully matched passive resistor network, creating a wide, open and natural stereo image.

Compatible with every professional DAW and virtually any balanced audio interface.

Why Analog Summing?

Passive analog summing offers benefits impossible to recreate with simple digital summing.

Benefits include:

• Bigger stereo image
• Better instrument separation
• Improved transient response
• Increased analog headroom
• More natural low-end
• Smooth high frequencies
• Better depth perception
• Easier mix balance

Drive your output converters slightly hotter into the summing mixer to introduce subtle analog saturation and harmonic richness while maintaining excellent transient headroom.

STM – Stereo or Mono Input Switch: It provides an extra stable Real Analog Mono Base for your mix (on monos like Kick/Bass/MainVox/Snare and so on), saving precious digital-to-analog (DA) channels (so you don’t waste stereo L/R for a mono instrument), and offers superior separation and 3D depth for the rest of your stereo instruments. This feature turns L/R inputs ‘COMBINED’ (two hard-panned L/R inputs) into an absolutely centered mono signal (1 x stereo to 2 mono). For example, ‘SNARE’ on channel 1 (left), ‘KICK’ on channel 2 (right). Mono instruments in the DAW sequencer (Steinberg cubase, pro tools, flstudio, reaper, logic pro, Ableton etc.) should place the kick hard left, the bass hard on the right, and so on. Stereo instruments: If you don’t use mono channels in your mix, simply turn down all the mono switches, and you’ll have a fully stereo analog summing mixer with panning options available from the DAW. See documentation and audio examples…

Mono Mode Routing from DAW:

• In 1: Mono Kick

• In 2: Mono Bass

• In 3/4: Snare, hi-hats, some percussion → Stereo

• In 5/6: Percussion, toms, synth blips, etc. → Stereo
  Panning from DAW is available for 3/4, 5/6, stereo inputs.

Stereo Mode Routing from DAW:

• In 1/2: Main Stereo tracks → Stereo

• In 3/4: Kick, Snare, hi-hats, some percussion → Stereo

• In 5/6: Percussion, toms, synth blips, etc. → Stereo
  Panning from DAW is available for all stereo inputs.
