Colour Duo 2-Channel Colour Channel Strip Kit

$500.00 $650.00

The Colour Duo is the ultimate tool for adding analog color to your tracks. Each of the Duo's two channels is a full channel strip, with mic preamps, line inputs, and three Colour slots each.

You can purchase the Colour Duo kit on its own or with one of our Colour Bundles. The bundles contain stereo pairs of each Colour, so six Colours each. To learn more about each bundle, check out our Colour Format Page.


The ultimate Colour Palette

With the Duo we set out to make the Colour Palette of our dreams. Each channel features three Colour slots, with their own independent controls and bypass switches. 

New to the Colour section is the much-requested wet/dry mix control. The MIX knob allows for versatile parallel signal processing without making extra tracks in your project file. Push your Colour modules as hard as you’d like, and blend in the dry signal till you get exactly the sound you’re searching for.

The Colour Duo is the first Colour Palette that lets you swap Colours on the fly without any tools. Simply loosen the thumb screws on the front panel and the entire panel slides out, giving you immediate access to the Colours at any time.


World-class preamps

The Colour Duo features the same pristine mic preamps that made the CP5 our best-selling kit. With exceptionally low noise and 66dB of gain, this isn’t your interface’s built in preamp. Once you hear them at work, you won’t hesitate to record your most important sources with them.

The Colour Duo’s line input is an independent stage that bypasses the preamp completely. And since the line and mic inputs come in on separate jacks, you can keep both connected and just switch between them with the LINE/MIC button on the front panel. 


Versatile connectivity

We gave you all the connectivity we could think of. Why? Because we like you and we hate adapters as much as you do. We even equipped a power THRU jack so you can power multiple Colour Duo units from one supply.


Using the Duo

Two Channel Mic Preamp

Track your two most important sources or a stereo pair with the Duo's two world-class preamps. You can track clean to process later, or engage Colours for processing on the way in.

Dual Channel Strip

Use the two channels as line inserts to bring real hardware color to your tracks. Warm up a vocal with saturation or push a room mic to the extreme with a compressor.

Stereo Bus Processor

Add punch to a stereo drum bus or glue your entire mix together with tape and transformer saturation.

What the Pros are Saying

"So, do I like it? Hell yes, I like it! As I mentioned, I’m a long-time fan of DIYRE’s work and use their CP5 and EQP5 (preamps and EQs, respectively) all the time. I love the Colour Duo preamps for the same things I love the CP5 for: overheads that have all the depth and pinpoint definition of a beautiful drum kit, acoustic guitars that sound like they are right in front of the listener, and strings that need to shimmer through a mix. Combine these gorgeous sounding preamps with the options available in the Colour modules, and you can create almost any flavor of preamps you want. Not to mention, you’ll have a new processor for mix bus or track insert duties allowing you to add transformers, compressors, or EQ curves – the Colour world is deep and constantly evolving!"

Block Diagram

Audio enters the Duo through either the MIC IN or LINE IN. The MIC IN can amplify the mic signal up to 60dB, while the LINE IN has a fixed attenuation of -6dB. The MIC/LINE switch selects which input is sent to the rest of the unit.

Signal is then sent to the Colours in series. Each Colour contains a bypass switch, and a dual-gang potentiometer which controls gain before the Colour and attenuation after. The Colours feed a gain/trim stage to make up for the gain or loss from the Colours. This signal then feeds the wet/dry mix stage, where it is summed with the dry signal from before the Colour section. The COLOUR switch selects between the output from the mix stage or the output from the MIC/LINE switch. This feeds the balanced output which provides +6dB gain.

Colour Duo Review

Using it on the 2-buss. Works great. There are a few colour modules I want to try but they're out of stock. Works as advertised with the modules I currently have. I will be using the pre's for tracking soon.

Just finished my build for my Colour Duo along with a few modules. Very happy with the results. I appreciate very much the idea behind buying a single unit and being able to color the sounds in so many different ways. As far as bang for your buck goes, I don’t think you can do much better than this on the hardware side.

The build is a marathon. Be prepared to be patient. Completed it over three lengthy sessions.The build instructions are excellent, and tools are included to help you keep components organized and placed properly.

Can’t wait to build more projects from DIYRE!

Colour Duo

Bought a kit in 2022. Finally assembled it in early 2023. The only assembler error was installing the header pins upside down; other than that, the assembly of the vast multitude of parts went smoothly. The assembly guide is excellent. My Colour Duo has no colour (so far), as it is used for live recording of classical music concerts, from solo to chorus and orchestra. I have little exposure to mic preamps, but the Colour Duo easily sounds better than my small mixer. Highly recommended. Thank you, Peterson!

A little or a lot of color

Purchased built...The DIYRE Color Duo is everything I hoped it would be. A super clean set of stereo pres and a stereo line-level coloring device that goes from super subtle to not so subtle. I use this to replicate Neve, API and SSL channels during tracking and mix down. And I use the color cards to add color to individual instruments. The pull out drawer is fantastic and lets me swap out color modules with ease.

ColorDuo The magic toolbox every engineer has to have !!!!

I have 4 colours of all the options and I can only say wow, it's the perfect toolbox to have a lot of options in a small space and not only that, being able to combine those colours makes it even more magical!

i love this product!
