Mixer, Attenuator Modules by the numbers
Measured across all 64 models we track, not a sample.
Median $106 — half of all mixer, attenuator modules here cost less.
How to choose the best mixer, attenuator modules
Signal-to-Noise Ratio
This is HUGE. A noisy mixer will ruin a subtle patch. Expect a bit more hiss than a top-tier unit in this budget, but it shouldn't be overwhelming. Listen for it in quiet passages - that's where cheap pots and op-amps really show their flaws.
Attenuation Accuracy
How consistently does the attenuator reduce the signal? Inaccurate attenuation throws off your tuning and timbre. We're looking for something that tracks reasonably well across its range, even if it's not perfectly linear.
Pot Quality & Feel
Cheaper pots can feel scratchy, loose, or just plain unpleasant to use. This impacts your workflow and inspires less experimentation. A smooth, responsive pot is worth its weight in gold, even in a budget module.
Number of Channels & Features
Do you need a simple two-channel attenuator, or a full-blown mixer with panning and EQ? Balancing features with price is key - more channels often mean compromises elsewhere.
Power Consumption
Every milliamp counts in a Eurorack system. A power-hungry module can eat into your available headroom and potentially cause instability. Check the specs and plan accordingly, especially if you're running a smaller power supply.
Buying guide
So, you're diving into modular and realizing quickly that summing signals can get messy fast. You need a mixer, or at least an attenuator module, to wrangle those oscillators and filters. Let's be real, Eurorack real estate is expensive, and we're not all blowing thousands on a Doepfer behemoth. Here's a look at some solid mixer/attenuator modules you can snag for under $200 that won't leave you feeling like you got ripped off.
At this price point, don't expect pristine audio or perfectly calibrated attenuators. You're making a trade-off. A few bucks more often buys you better pots, a lower noise floor, and more accurate attenuation.
Focus on modules with good user reviews - those experiences are more valuable than marketing hype. Seriously, a little noise is preferable to a module that's flaky and unreliable.

Questions
Can I use these modules for live performance?
Absolutely, but be mindful of the noise floor. A little hiss is one thing, but a loud hum can be a real problem on stage. Test thoroughly with your entire rig before a gig.
What's the difference between an attenuator and a mixer?
An attenuator reduces signal level, a mixer combines multiple signals. Some modules do both, but a simple attenuator is great for level matching and basic signal shaping.
Are there any truly 'silent' options under $200?
Not really. Expect a little hiss. Modules using higher-end op-amps (like TL072 or even better) will be quieter, but those are rare in this price bracket.
What about DIY options?
DIY kits can be a great value, but require some soldering skills and patience. The quality can vary wildly depending on the designer and your build quality - do your research!
I'm on a super tight budget. What's the absolute minimum I need?
A single, basic two-channel attenuator module will get you started. It's better to have something than nothing when you're trying to balance signals and avoid clipping.
