Mixer, Attenuator Modules by the numbers
Measured across all 96 models we track, not a sample.
Median $156 — half of all mixer, attenuator modules here cost less.
How to choose the best mixer, attenuator modules
Signal Integrity
Cheap mixers can introduce noise or muddy the signal. You want something clean, especially when dealing with sensitive oscillators or subtle modulation. A little hiss is annoying, a lot is unusable.
Attenuation Range
Being able to dial down a signal's amplitude is crucial for balancing levels and creating interesting effects. A wide range (e.g., -60dB to +10dB) offers more flexibility.
Routing Flexibility
How many inputs do you need? Can you route signals internally? Simple is good for beginners, but future-proofing is smart. Think about how many voices you realistically want to blend.
Ease of Use
Complex layouts and tiny knobs can be overwhelming. Look for clear labeling, intuitive controls, and a size that's comfortable to work with. You don't want to spend more time fighting the module than making music.
Power Consumption
Modular synths already draw a decent amount of current. Modules that are power hogs can overload your power supply, so check the specs and factor that into your overall system design.
Buying guide
So you're diving into the modular world? Awesome! But before you start patching oscillators to filters, you'll quickly realize you need a way to wrangle all those signals. Mixer and attenuator modules aren't the flashiest, but they're the unsung heroes of any modular setup - they're essential for getting a coherent sound and actually making something musical. Let's break down what beginners need to know.
For beginners, simplicity and clean signal path are paramount. Don't chase the 'boutique' vibe just yet - focus on functionality. You'll see a lot of modules with stepped attenuators (clicks as you turn) versus smooth ones; stepped are often cheaper and perfectly fine for learning, but smooth knobs offer more nuanced control.
Remember, a decent mixer is an investment; it's the glue that holds your modular system together. Cutting corners here will make everything else sound worse.

Questions
What's the difference between an attenuator and a mixer?
An attenuator just reduces a signal's level. A mixer combines multiple signals, often with individual attenuation controls for each. Most mixers include attenuators, so you'll often see them used interchangeably.
How many inputs do I really need?
Start with 4-8 inputs. It's better to have a few extra than to constantly be patching in and out of a small mixer. Think about the number of sound sources you realistically want to blend - oscillators, filters, effects, etc.
What does 'headroom' mean in this context?
Headroom refers to how much extra signal a mixer can handle before distortion. More headroom means you can push your signals harder without clipping. Beginners generally don't need tons of headroom, but it's a nice-to-have.
Are there any good, affordable options?
Mutable Instruments offers the Waveshaper which functions as an attenuverter. Intellijel has the QuadMix II which is a solid, reliable choice. Befaco has some interesting, more budget-friendly options too, but listen for noise before committing.
Can I use a regular audio mixer instead of a modular mixer?
While technically possible, regular audio mixers aren't designed for the low-level signals and patching flexibility of modular synthesis. You'll likely encounter issues with impedance matching and signal integrity.
