1U & 3U Eurorack Modules • Threetom Mixing Flask soft-clipping utility mixer extraordinaire

Hi all, I released Mixing Flask during Dutch Modular Fest on the 31st of August.



The Threetom Modular “Mixing Flask” is a utility mixer offering mix-bus limiting and a cornucopia of indicator lights integrated behind a unique chemical lab-inspired front panel.

I designed Mixing Flask as a solution to my three gripes with conventional utility mixers:

• Mixing too hot is too easy, leading to hard clipping on the mix-bus. And even when there’s an indicator light to warn you when this is happening, there are no features to actively prevent it.
• Utility mixers usually only offer unity gain, so when you have a weak input signal (like a MTM Radio Music), you’re out of luck.
• They’re nauseatingly boring.

Mixing Flask provides solutions to these annoyances in the following ways:

• I’ve implemented a soft-clipping limiting circuit on the mix-bus (inspired by Doppio). The highest setting prevents the mix-bus from hard clipping altogether in favor of warm saturation.
• All inputs have a gain of +6dB allowing you to better equalize between volumes while maintaining a hot mix-bus output.
• The myriad of indicator lights and front-panel graphics make you feel like a mad scientist in your own modular chemical lab. I bet you won’t find another utility mixer that makes mixing more exciting than Mixing Flask!

Features:

• Three DC-coupled mono input channels with an audio taper gain control, and a maximum input gain of +6dB
• Mix-bus with three different soft-clipping modes
  • Drive mode (gentle soft-clipping + hard clipping when pushed hard)
  • Off / linear mode (hard-clipping like a traditional utility mixer)
  • Limit mode (firm soft- knee limiting)
• Split-polarity indicator lights per input channel
• Split-polarity metering on the mix-bus
  • Green (signal present)
  • Yellow (signal nominal/soft-clipping)
  • Red (hard-clipping warning!)
• Reverse power protection
• 4-layer PCB design with completely separate audio supply rails and ground

Yesterday MATTHS released his demo video for Mixing Flask
