Description

3x MIA Eurorack Mixer, Inverter and Attenuverter

The Happy Nerding 3x MIA combines three two-input mixer sections in a compact 6HP Eurorack module. Mix signals, adjust their levels, reverse their polarity or generate offset voltages using dual concentric controls.

Use the sections independently or link them with the normalization switches to build a four-input mixer plus a separate two-input mixer, or a single six-input mixer. Choose a silver or black panel to suit your setup.

Signal Control and Mixing Features

• Six inputs in three pairs: each section has A and B inputs and an A+B mix output.
• Dual polarizer controls: set the level and polarity of each input signal.
• Offset generation: an unpatched input lets its control generate an offset voltage from -5V to +5V.
• Flexible section linking: normalize section 1 into section 2 and section 2 into section 3 for different mixing configurations.
• Signal LEDs: visualize input intensity and help locate the zero-output control position.

Controls and Connections

Each input pair is mixed at its section's output, whether you are combining incoming signals, offset voltages or both. The controls have no center detent; the input LEDs help you find the center position when suppressing a signal.
