Matrix Mixer / Eurorack / PCB + Front Panel

Matrix Mixer

The Matrix Mixer Eurorack PCB and Front Panel Kit is a versatile DIY utility module designed for flexible routing and mixing of both audio and control voltages. With a simple and intuitive 4×4 matrix layout, it allows any input to be routed to any output with precise level control.

Key Features

• Eurorack PCB and front panel kit
• 4 inputs × 4 outputs matrix configuration
• Mixes audio signals and/or control voltages
• Individual level control for each input-to-output connection
• Beginner-friendly DIY build with straightforward circuitry
• Compact and intuitive matrix layout
• Front panel made from PCB material, screen printed by hand

Routing & Modulation

Each input can be freely routed to any of the four outputs, making the Matrix Mixer ideal for:

• Audio signal routing and blending
• Complex CV distribution
• Feedback and cross-modulation patches
• Creating evolving modulation relationships

Because the circuit supports both audio and CV, it functions equally well as an audio matrix mixer, a CV router, or a hybrid utility for advanced modular patching.

DIY Build & Front Panel

This beginner-friendly Eurorack DIY kit is suitable for builders new to modular synthesis or electronics. The circuit is simple and reliable, making it an excellent utility module for first-time builders.

The front panel is crafted from durable PCB material and hand screen printed, ensuring a consistent look alongside other Guru Gara Synth modules.
