Behringer 904B Voltage Controlled High Pass Filter Eurorack…
904B VC High Pass Filter · Behringer
7 for sale on Reverb1 finish at Thomann
This filter is great if you need a compact, cheap way to cut low frequencies in your rack. You can automate the cutoff with three CV inputs, and the two frequency ranges give you quick options. It works well as a simple tool, but the lack of gain and resonance controls means you won't get deep sound shaping. Perfect for beginners or those who just need to remove bass.
Pros
- Two distinct frequency ranges let you shape tone quickly.
- Compact 8 HP width fits tight modular cases perfectly.
- Three CV inputs let you automate the cutoff smoothly.
Cons
- Single high-pass mode lacks low-pass flexibility for full control.
- No gain or resonance knobs limit shaping the filter voice.

How to choose the best filter modules
Heritage/Accuracy
Behringer's really focused on nailing the sonic character of legendary filters like the Moog Ladder, Roland Juno, and Sequential Designs Pro. They're not perfect clones - there's always a Behringer 'flavor' - but the core essence is there, and often surprisingly close.
Tone Characteristics
The Moog-inspired filters offer that classic fat midrange honk, great for basslines and pads. The Juno filters give you that glassy, shimmering clean - think shimmering synth brass. The Sequential filters have a more aggressive, resonant character, perfect for cutting through a dense mix, but can get a bit ice-picky if you're not careful.
Build Quality
Let's be honest, these aren't built like a tank. The pots can feel a little scratchy, and the plastic case is...plastic. But for the price, they're surprisingly robust; I've gigged with them for years and haven't had any catastrophic failures, just a few wobbly pots that needed a bit of contact cleaner.
Versatility
While they're often modeled after specific synths, these filters are surprisingly versatile. You can use them to add character to external signals - guitar, vocals, drums - or as a creative element within your modular setup. Experiment with resonance and drive to really push them.
Value
This is the big one. The sheer affordability of Behringer filters is a game-changer. They open up the world of modular synthesis to a much wider audience and allow you to experiment with different filter types without breaking the bank.
Buying guide
Okay, let's talk Behringer filter modules. For years, Eurorack felt like an exclusive club, and filters, arguably the heart of any synth voice, were ridiculously expensive. Behringer changed that, bringing classic filter emulations to the masses. But are they good? That's what we're digging into - these aren't just cheap clones; they're a chance to explore classic tones without mortgaging your apartment.
Look, these aren't going to replace a vintage Moog, but for the price, they're an incredible value. The pots can be a bit finicky, so budget for some contact cleaner. Don't expect bombproof construction, but don't baby them either.
If you're new to modular, these are a fantastic entry point; if you're a seasoned synth nerd, they're a great way to expand your sonic palette without emptying your wallet.

Questions
Are they just cheap knock-offs?
They're inspired by classic filters, not exact clones. They capture the core sound, but there's a slight Behringer signature - sometimes a bit more aggressive, sometimes a bit more saturated. It's not always a bad thing.
The pots feel scratchy - is that normal?
Yeah, it's pretty common. A little contact cleaner usually does the trick. It's a trade-off for the low price point.
Can I use these with non-modular synths?
Absolutely! They're voltage-controlled, so you can use them to process external audio signals. You'll need a way to control the cutoff frequency with a CV source, though.
Which filter should I get first?
It depends on your taste. The Moog-inspired filter is a great all-rounder. If you're after shimmering, glassy tones, go for the Juno. For aggressive, resonant sounds, the Sequential filter is your best bet.
Are they noisy?
Some of the earlier models had a bit of noise, but Behringer has been working on improving that. Generally, they're not excessively noisy, but you might hear some hiss at high resonance settings. It's part of the character, really.
