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 Doepfer A-101-8 Photo Phasing VE is a really cool, characterful phasing module. The photo resistor-based design gives it a warmth and unpredictability you don't often find in digital phasing. It’s perfect for experimental sound design and adding subtle movement to pads and drones – a great value for a unique sonic texture.
Pros
- Photo resistors offer a uniquely organic, subtly shifting phasing effect.
- Eight stages provide a wide range of phasing possibilities, from subtle to wild.
- Dedicated feedback control allows for self-oscillating, swirling textures.
Cons
- The all-pass design can be a bit muddy at extreme settings, losing clarity.
- 4HP width can be restrictive in smaller Eurorack cases; space is a premium.

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
-
You get a Eurorack phase shifter with eight all-pass filters and a built-in LFO for automatic sweeping. It also has Phase CV and Rate CV inputs, so you can control it from other modules. It suits you if you already use a Eurorack system and want a phaser with plenty of control over its movement.
Pros
- Eight all-pass filters make up the phase shift path
- Photo resistors handle control of the filters
- Built-in LFO offers rate control and two selectable waveforms
Cons
- Resonance path filter count is set on the rear DIP switch, not the front panel

How to choose the best phase shifter modules
Rate/Speed Control
This isn't just about how fast the swirling happens. Look for a wide range, and ideally, modulation input to tie it to LFOs or envelopes for evolving textures. A fixed rate is fine for some sounds, but flexibility is king.
Depth/Intensity
This controls how much the signal is shifted. Too little and it's inaudible, too much and it's just a warbly mess. A good module will have a sweet spot where the effect is noticeable but still musical.
Stereo Image
Many phase shifters are mono, which is fine, but a stereo phase shifter can create a massive, swirling soundscape. The wider the stereo field, the more immersive the experience - but be mindful of phasing issues with mono playback.
Tone Color
Some phase shifters are bright and sparkly, others are darker and more subtle. This is a crucial element; a harsh, ice-picky top end can ruin a pad, while a warm, organic phase can add depth to a bassline. Consider how it will interact with your other modules.
Modulation Input
This is where things get interesting. A modulation input allows you to use LFOs, envelopes, or even audio signals to control the rate or depth of the phase shifting. This can create incredibly complex and evolving textures, moving beyond a static effect.
Buying guide
Alright, let's talk phase shifters in the modular world. They're not just for cheesy 70s funk anymore - a good phase shifter can add movement and subtle texture to pads, leads, or even drums, giving them a swirling, almost liquid quality. But not all phase shifters are created equal; some are just thin and brittle, while others offer a truly hypnotic, evolving sound. This guide will help you cut through the noise and find a phase shifter that actually inspires you.
Cheap phase shifters often thin out the signal and lack a useful range of motion - that 'sweet spot' where the effect is musical. Paying more generally gets you better component quality, a wider range of control, and often a more nuanced tone. Don't be fooled by excessive knobs; a few well-implemented controls are far more valuable than a panel full of noise.

Questions
What's the difference between a phase shifter and a chorus?
Both involve modulating the phase of a signal, but a phase shifter typically has a more dramatic, swirling effect, while a chorus creates a thicker, more layered sound. Think 'psychedelic swirl' vs. 'choir of synths'.
Can I use a phaser on bass?
Absolutely, but be careful. Too much phase can make a bass sound muddy or weak. Subtle use with a slower rate can add movement and cut through the mix without losing low-end thump.
Does stereo phase shifting always sound good?
Not necessarily. Extreme stereo phasing can cause issues when played back in mono (like live). Experiment with the stereo width to find a balance between spaciousness and compatibility.
I'm new to modular, where should I start?
Start with a simple, well-regarded module. Don't get bogged down in features you don't understand. Focus on learning how the effect interacts with your other modules before chasing complex modulation schemes.
What's the deal with feedback on phase shifters?
Some modules offer feedback, which essentially sends the output of the phase shifter back into its input. This can create intense, swirling, and sometimes chaotic sounds - great for experimental textures, but be prepared for runaway feedback!
