If you run a Eurorack setup and want to mix several sound sources, this module gives you six channels to work with. Each one has its own panorama, EQ, mute and volume, and the master section adds a 3-band EQ and master volume. You can also grow it later with the Hexpander and Hex Mix VCA.
Pros
- Six channels, each with its own panorama, three-band EQ, mute and volume control
- Per-channel mute available as both a switch and a button
- Level LEDs show signal level on each channel
Cons
- Draws 106 mA on +12 V and 88 mA on -12 V, so it needs a Eurorack power supply

Mixer, Attenuator Modules by the numbers
Measured across all 97 models we track, not a sample.
Median $155 — half of all mixer, attenuator modules here cost less.
How to choose the best mixer, attenuator modules
Signal Integrity
Cheap attenuators can introduce noise or distort the signal, especially when attenuating significantly. We're talking about whether you get a clean, transparent reduction or a muddy, fizzy mess - and whether that's even desirable, sometimes a little grit can be cool.
Attenuation Range & Accuracy
A narrow attenuation range limits your creative options. Accuracy matters too - a 10dB attenuation should actually be 10dB, not 9.5 or 11.2. This directly impacts your mix balance and modulation response.
Routing Flexibility
Beyond simple left/right, consider modules with aux sends, pre/post fader switching, and even panning capabilities. Live, you'll want to quickly re-route signals to handle feedback or EQ adjustments; in the studio, it's about creating layered textures.
Noise Performance
Let's be honest, Eurorack is inherently noisy. A good mixer/attenuator minimizes that noise, especially when dealing with multiple oscillators and filters. A noticeable hiss can ruin a subtle patch.
Hands-On Control & Layout
A cluttered or unintuitive layout slows down your workflow. Look for modules that offer clear visual feedback and controls you can adjust without staring at a spreadsheet of patch cables.
Buying guide
Alright, so you've moved beyond basic modular patching and are actually shaping your sound, not just routing it. That means you need mixer and attenuator modules that can handle complex modulation, intricate signal flow, and the demands of a live rig. It's not about just blending signals anymore - it's about sculpting them, and that requires a different level of precision and flexibility. Let's talk about what you actually need, not just what's 'cool' on Instagram.
Don't get lured in by flashy aesthetics. A module that looks cool but introduces significant noise or lacks essential features is just a paperweight. Paying extra for accurate attenuation, low noise, and flexible routing is almost always worth it, especially if you're gigging.
Many cheaper modules cut corners on component quality, resulting in noticeable distortion or a higher noise floor - things you'll hear the moment you try to get subtle. Think of it like a good preamp - you don't notice it when it's doing its job, but you definitely notice when it's not.

Questions
What's the difference between an attenuator and a mixer?
An attenuator primarily reduces signal level. A mixer combines multiple signals. Many modules combine both functions, but understanding the core difference helps in patching - an attenuator is great for modulating a single signal's level; a mixer is for blending multiple sounds.
My module introduces a lot of noise. Is that normal?
Some noise is inherent in Eurorack, but excessive noise indicates a problem. Check your power supply, grounding, and cable connections. If the noise persists, the module itself may be faulty.
What's the benefit of pre/post fader switching?
Pre-fader allows modulation sources (like LFOs) to affect the signal before the overall level is adjusted by the fader. Post-fader means the modulation happens after the fader, so the modulation's effect is consistent regardless of the fader position - useful for subtle swells or creating a base level before modulation.
How important is headroom?
Headroom is crucial for avoiding clipping and distortion, especially when stacking multiple modules. More headroom means more dynamic range and cleaner signals, particularly important for aggressive sounds or complex modulation schemes.
Are there any modules that are particularly good for live performance?
Modules with robust build quality, clear labeling, and intuitive layouts are essential for live use. Look for features like aux sends for external effects and pre/post fader switching for quick adjustments on the fly.
