Audio transformers are key players in the sound of countless classic pieces of analog equipment. Often dubbed "the sound of iron," the complex, dynamic character of a good transformer is notoriously difficult to emulate. So why try when you can have the real thing? CTX brings the classic sound of iron to the Colour format in the best way possible: with a real Cinemag transformer.

CTX allows the custom-wound Cinemag transformer to work its inimitable magic on the signal. At moderate operating levels, the transformer's effect is vanishingly subtle, but can be perceived as making tracks sound more "finished" when stacked over numerous tracks. As levels increase the transformer's core begins to saturate, thickening the signal with low-frequency harmonics and natural compression.


  • Transformer wound by Cinemag in California
  • Steel core emphasizes the phase distortion and hysteresis effects associate with the "iron" sound
  • Compatible with the Colour 500-Series Palette
  • Red PCB!
  • Full, step-by-step assembly instructions and guaranteed support


We encourage you to order from our UK distributor, Big Bear Audio, to save the 20% import VAT.

The samples below provide a quick glimpse into the CTX Colour's tonal character. The samples were taken by running the dry signal through the Colour 500-Series Palette with only CTX engaged and Saturation set to 50%.

Real analog plugins.

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.
