HRK Colour Modules – True Analogue Plugins!

Colour Modules are Hardware Analogue Plugins made with NOS Discrete Components and Valves which add pleasing harmonics and subtle saturation to the signal, delivering the sonic results of the Vintage Studio Equipment for a fraction of the Price!

Each Colour Module is different and uniquely impacts the sound. You can use the Colour Modules for Recording, Tracking and Mastering.

What benefit I will get from Colour Modules?

The modern DAW systems can produce great results, but most of the sound engineers and music producers will admit that the mix produced with DAW is missing something… some special ingredient, which is the analogue magic.

This is why the big recording studios have racks filled with vintage preamps, compressors and equalizers. The HRK Colour Modules are real Analogue Plugins which will help you to make better recording and mixes standing out from the crowd.

HD Audio Samples

Audio Samples are level matched. The subjective loudness difference is a result of the native compression effect introduced by the British Driver Colour Module.

How to use the British Driver Console Colour Module.

The British Driver is easy to use saturation colour module.

In low levels of drive, the saturation will be suttle.

For medium levels of drive, the saturation effect will become audible.

At the overdrive level, the asymmetric clipping will produce audible levels of THD.
