If you build a modular rig, this module gives you two ring modulators in one 4TE panel. It multiplies two signals together and handles both positive and negative voltages, which is what sets it apart from a VCA. It suits you if you want bell-like sounds or speech alienation, and you will need a supply that provides 12V and -12V.
Pros
- Contains two separate ring modulators in one module
- Multiplies two inputs, X * Y, to produce the output
- Handles both positive and negative input voltages (4-quadrant multiplication)
Cons
- Needs 12V and -12V power, drawing 40mA and -30mA
- Takes 4TE of rack width and 40 mm of depth

7 for sale on Reverb1 finish at Thomann
You might like this module if you build a modular rig and want to blend two signals together. It also works as an insert, so you can run an external effect through it. Its small size and low power draw make it an easy fit for a Euro rack.
Pros
- Works as a crossfader that blends between two signals in one module
- Can also sit inside a signal path as an insert for external effects
- Compact 8 HP width fits easily into a Euro rack format
Cons
- Only 8 HP wide and 40 mm deep, so it needs rack space to fit

2 for sale on Reverb1 finish at Thomann
If you build Eurorack setups, this module gives you two jobs in one 16 HP panel: ring modulation and voltage-controlled amplification. You get two signal inputs, two adjustable CV outputs for steering external oscillators, and gate inputs to switch modes. It suits you if you want a compact way to modulate and shape signals in your rack.
Pros
- Ring modulator and VCA combined in one 16 HP Eurorack module.
- Two signal inputs, each with its own level control.
- Switch between MOD and UNMOD mode to use it as a ring modulator or a VCA.
Cons
- Draws 60 mA (+12 V) and 45 mA (-12 V), so your Eurorack power supply must provide both rails.
-
You get a small module that fades between signals, and it works with both audio and control voltage. It suits you if you build a modular rig and want a compact way to crossfade sounds. It takes up little space and draws little power, so it works well for builders with a tight case.
Pros
- Crossfades audio signals as well as CV signals under voltage control
- Dual VC design gives two voltage-controlled crossfade channels in one module
- Compact 4 HP width fits into a modular case with limited space
Cons
- Only 4 HP wide and 45 mm deep, so your case needs room to fit it
-
This is a small Eurorack module that does two jobs. It turns triangle waves into sine waves, and it can blend two signals using a control voltage. It suits you if you build a modular setup and want a module that takes up little space.
Pros
- Combines two functions in one compact module: sine converter and VC crossfader.
- Converts triangle waves to sine waves.
- Voltage-controlled crossfader lets you blend two signals with a control voltage.
-
You get a voltage-controlled panning module with two VCAs that work in opposite directions. It can pan a sound between left and right, pan between two audio signals, or do both at once. It suits you if you already run a modular synth and want to move sounds around with an LFO, envelope, or other control source.
Pros
- Two linear VCAs that move in opposite directions under one control voltage
- Three audio outputs: VCA1, VCA2, and a Mix output
- Manual panning plus two external control voltages, one with an attenuator
Cons
- Works with control sources like LFOs and envelopes, which you must supply separately
-
You get four useful tools in one small Eurorack module. It covers ring modulation, noise, sample and hold, and an LFO, so you can build patches that change and move on their own. It suits you if you already run a Eurorack setup and want more modulation sources without using up much case space.
Pros
- Analogue ring modulator for metallic, bell-like sounds
- White noise and pink noise on two separate outputs
- Sample and hold unit with clock out, external clock in, and clock rate and lag time fader
Cons
- Needs a free 16 HP slot in your Eurorack case, so plan your space first
-
This is an active ring modulator with an SSI2162 VCA module, and it works with both audio signals and control voltages. At 6 TE wide and 32 mm deep, it takes up little space in a small modular rack. It suits you if you want a ring modulator for your modular setup and your power supply has enough capacity for its draw.
Pros
- Active ring modulator built around an SSI2162 VCA module
- Handles both audio signals and control voltages
- Compact 6 TE width fits small Eurorack setups
Cons
- Draws 25mA on +12V and 20mA on -12V, so your power supply needs room for it
-
The Zlin is a small Eurorack crossfader with two inputs, A and B, and a CV input that lets a voltage control the blend. Its aux output can sum or mirror input A, or send out CV, so it does more than one job. If you build a modular rig and want a compact way to fade between two sources, you will find it handy.
Pros
- Two inputs, A and B, let you blend two signals together
- Voltage-controlled crossfader with a CV input for modulated mixing
- Built-in LED shows the crossfader position at a glance
Cons
- Only 3 HP wide, so there is little room for extra controls

How to choose the best ring modulator, crossfade modules
Ring Modulation Algorithm
Some rings are pure, others add subtle waveshaping. A clean ring mod gives you the purest metallic interaction, letting the source signals shine. Waveshaping can add character, but can also muddy the tone - experiment to see what you prefer, but be aware of the trade-off.
Input/Output Level
A weak input stage can clip easily, while a weak output means you'll be chasing gain. You want headroom, especially if you're planning on running this through distortion or other gain-hungry effects. A module that consistently needs to be maxed out isn't giving you much flexibility.
Crossfade Time Range
A slow crossfade is subtle, a fast one is abrupt. Look for a wide range that lets you create everything from smooth transitions to stuttering rhythmic patterns. The ability to modulate the crossfade time is a huge bonus for evolving textures.
Noise Floor
Ring modulators, especially analog ones, can be noisy. A low noise floor means your subtle textures aren't buried under hiss. This is critical for quiet, ambient patches or clean recordings - the noise will be amplified by any processing.
Build Quality & Calibration
A flimsy pot or a poorly calibrated ring can ruin the experience. Solid construction and accurate calibration ensure consistent results and longevity. Cheap modules often use inferior components that will fail prematurely, especially with frequent use on stage.
Buying guide
So you're diving into ring modulation and crossfades in your modular setup? Smart move - they're sonic rabbit holes, capable of everything from metallic clang to evolving textures. Ring modulators can turn a mellow pad into something truly unsettling, while crossfades let you sculpt movement and rhythmic complexity. Let's break down what to look for to avoid buying a module that sounds like a cheap toy and actually delivers the weirdness you're after.
Don't be swayed by flashy graphics or marketing buzzwords. Ring modulators and crossfades are often the modules where corners get cut - cheap pots, noisy op-amps, limited input/output range. If you're on a budget, prioritize a clean ring modulator over a fancy one with waveshaping.
For crossfades, a wide time range and modulation input are more valuable than a bunch of extra features you won't use.

Questions
Can I use a ring modulator as an overdrive?
Technically, yes, but it won't sound like a traditional overdrive. It'll add metallic harmonics and a strange, dissonant flavor. It's more for creating textures than a warm, saturated tone.
What's the difference between a ring modulator and a wave shaper?
A ring modulator produces frequencies that are the sum and difference of the input signals - it's a specific mathematical operation. A wave shaper distorts the waveform in a more general way, adding harmonics and altering the overall tone. They can overlap in effect, but they're fundamentally different.
I'm getting a lot of noise - is that normal?
Some noise is inherent in analog ring modulators, but excessive noise indicates a problem. Check your patching, ensure proper grounding, and if the noise persists, the module might be faulty.
Can I use a ring modulator for vocal effects?
Absolutely! But be prepared for some seriously weird results. It's great for creating robotic voices or adding metallic textures, but it's not exactly subtle.
What voltage control signals work best for modulating a crossfade?
Anything slow and evolving is gold - LFOs, envelope followers, even random voltage generators. Experiment with different modulation sources to create rhythmic patterns and evolving textures. Fast, abrupt signals can create glitchy, stuttering effects.
