Colourupter Optical Disrupter Colour

The Colourupter brings the unique mojo of XQP Audio's Optical Disrupter to the Colour format. At the heart of the Colourupter's sound is a classic optical compressor employed in a deviously non-traditional way: instead being converted to a DC control voltage, the audio signal is sent directly to the side chain. This "incorrect" implementation paired with the natural character of the optical element yields a soft, asymmetrical distortion that remains musical even at extreme gain settings.


  • Optical element gently slopes waveform without hard clipping
  • Emphasis on bass harmonics creates a larger-than-life low end
  • Compatible with the Colour 500-Series Palette
  • Full, step-by-step assembly instructions and guaranteed support

Colour is a new format for analog audio gear designed for and by the DIY community. We took our favorite sounding analog circuits and put them on modules that are small, affordable, and swappable.

The Colour format consists of Colours and Palettes:

Colours are ultra-compact, pluggable analog circuit blocks that impart various types of analog color. Check out our ever-growing selection of Colours. Colours can be designed and released by anyone.

Palettes provide controls, power, and support circuitry for Colours. We currently offer the Colour 500 Palette and CP5 Mic Preamp with Colour.

Beautiful Sound

This sounds absolutely gorgeous on a range of material. Adding texture to bass drums or pushing the whole mix through it, this adds that bit of magic. The harmonics are musical and pleasant. This is not harsh at all and brings that desirable warmth. Well done XQP and DIYRE, inspiring collaboration and great product. Now.......need to buy another!

I couldn’t believe how fast and personal the service was when I made a mistake in my kit. My pair of palettes is now the favorite thing in my rack. Excellent experience!


I LOVE this, it responds so differently to different sources. I have a pair and I'm loving it on sampled orchestral stuff within my electronic tracks, but it's great on anything, so far. My favourite colour. I have a rack of much more expensive gear and this is getting most of the work lately.

Simply the best one so far

Ok So I don't know what took me so long to buy the optical disrupter, but had I known, it would've been my first choice from day one. Im an electronic music producer and use my colors to record my synths with an added flavor. I typically split my signal in the patchbay and record my dry signal on one stereo side, and the return of my colour rack in the other stereo input. Then I can use the pan button as a wet/dry inside my DAW. Of course it require to merge in mono in an aux track after. I STRONGLY recommend always recording both dry and wet signal when you use the colours, as they sound a lot fatter if mixed with the original sound. Now I have the LTL pentode tube, the cinemag, the multi stage saturation, the tape ips and the optical disrupter. I couldn't live without any of them by now, but the optical disrupter is now my favorite, I will have to perform more tests but for drums it's EXACTLY what you need. It has this sharp edge giving a soft grain but very efficient to enhence any drum, especially snare and hihat (TR-8 type). Can't recommend it enough. If i Had only 3 colours, the other 2 would be the pentode and the cinemag. I heard you can reproduce the pulteq effect by merging the rogue tech colour to the pentode, will have to try it out soon, but so far, those 3 are the "can't go wrong" choice.


Easy build, really colourful destroyer. Not nearly as 'spitty' as the ToneLoc Colour and a softer attack. Really breathes life into Drums and blues/roots guitar (really liked it on slide!)
