Expert Sleepers Beatrix Phaser Eurorack Synth Module
Beatrix · Expert Sleepers
11 for sale on Reverb1 finish at Thomann
The Beatrix is an analogue phaser made for Eurorack modular setups. You get controls for frequency, feedback, depth and input level, plus CV inputs so you can change those settings with other modules. It suits you if you already have a Eurorack case and want a phaser you can shape with control voltage.
Pros
- Analogue phaser built for Eurorack modular setups
- Controls for frequency, feedback, depth and input level
- Phase switch chooses effect only or effect mixed with the original signal
Cons
- Needs a Eurorack case with +12V and -12V power to run

This is a phaser module for a Eurorack modular setup. It has eight all-pass filter stages, controls for phasing offset, feedback, wet/dry mix and input level, and two outputs for stereo use. If you already build with Eurorack and want a phaser you can control with voltage, this one is a good fit.
Pros
- Eight all-pass filter stages give a deep phasing effect
- Photoresistors are used in the all-pass filter design
- Controls include phasing offset, feedback, wet/dry mix and input level
Cons
- Power draw is 30mA on both +12V and -12V rails, so it needs a Eurorack power supply

You get this module if you build a Eurorack setup and want a VCO signal split into four phase shifted copies. It is 14 HP wide and draws little power, so it fits easily in a standard rack. If you like working with phase effects on oscillators, this is a simple, compact option.
Pros
- Generates four phase shifted copies of a VCO signal applied to the audio input
- Eurorack format fits standard Eurorack modular racks
- Compact 14 HP width saves rack space
Cons
- Works only with a VCO signal fed into its audio input

You get a six-stage analogue phaser, a delay section for flanger and chorus effects, an LFO and a gate delay in one 16 HP module. It suits you if you build Eurorack setups and want movement effects you can control with voltage. The modulation intensity can be set by the internal LFO or by a CV input, so your patch can change over time.
Pros
- Analogue six-stage phaser with controls for shift frequency, resonance and modulation intensity
- Delay section covers flanger and chorus effects, with adjustable delay time, resonance and modulation intensity
- Built-in LFO with triangle and inverted triangle outputs, running from 0.02 to 10 Hz
Cons
- Draws 60 mA from both the +12 V and -12 V rails, so it needs a Eurorack power supply
How to choose the best phase shifter modules
Depth/Intensity Control
A good phase shifter needs real depth control. It's not just about 'on' or 'off'; you want to dial in subtle chorus-like movement or a full-on swirling vortex. Cheap ones often lack this nuance.
Rate/Speed Control
Similar to depth, rate control needs to be useful, not just a fast/slow switch. A wider range with finer adjustments is essential for finding the sweet spot, whether you're going for a slow, watery effect or a fast, almost tremolo-like shimmer.
Tone Color/Character
Some phase shifters just sound... sterile. The best ones impart a subtle coloration - maybe a little warmth, maybe a touch of grit - that complements the signal being processed. This is often a product of the component choices and circuit design.
Noise Floor
Budget modules sometimes cut corners on component quality, leading to increased noise. This can be a real problem in quieter passages or when layering with other signals. Listen carefully for hiss or hum.
Modulation Stability
Cheap voltage-controlled oscillators (VCOs) can drift, leading to wavering or unstable phase shifting. A stable LFO is crucial for predictable and musical results. Check how the rate changes with voltage changes.
Buying guide
Okay, so you're chasing that swirling, psychedelic phase shimmer but don't want to mortgage your apartment for it. Believe me, I've been there. Phase shifters are essential for adding movement and interest to everything from glassy Rhodes chords to searing lead lines, and you don't need to spend a fortune to get a good one in your modular system. Here's a rundown of solid phase shifter modules you can snag for under $200.
At this price point, you're going to be making some trade-offs. Don't expect pristine, studio-grade performance. Generally, you'll find compromises in component quality, leading to a slightly higher noise floor or less precise control.
Focus on modules with a wide range of rate and depth - those are the features that will make a real difference in your sound. Used gear is your friend here; you can often find higher-end modules at a discount.

Questions
Can I use a phase shifter as a chorus effect?
Technically, yes, but it won't be a true chorus. Set the rate slow and the depth subtle, and you can get a watery, thickening effect. It's not as rich or complex as a dedicated chorus module, though.
What's the difference between a phase shifter and a flanger?
Both use a modulated delay, but a flanger typically has a shorter delay time and a more metallic, 'jet plane' sound. A phase shifter is generally smoother and more subtle.
I'm getting a lot of noise - what's going on?
Budget modules often use cheaper components that generate more noise. Try reducing the gain staging, shielding the module, or using a noise gate. It's a common issue.
Can I sync the phase shifter's rate to my sequencer?
Most modules will offer a CV input for rate control, allowing you to sync it to your sequencer or other modulation sources. Check the module's specifications for details.
Is it worth spending more for a better phase shifter?
It depends. If you're serious about sound quality and need precise control and a low noise floor, then yes. But for basic swirling effects and experimentation, a budget module can be a great starting point.
