The MP568C is a Studio Grade ultra-low noise Microphone Preamplifier with Instrument Input and Two-Colour Slots.

The MP568C is designed to process the sound with the use of Colour Modules by saturating and adding subtle harmonics to the signal, similar to the harmonics added by the vintage preamps.

The MP568C is a perfect choice for demanding professional recording applications. The input circuitry is based on the ultra-low noise, high-performance Verum’70 Discrete Input Class A Mic Preamp.

The logarithmic Gain control allows to accurately set the signal level fed to Colours or record from the microphone with the selected Colour Module.

Addition of Colour Modules increases the flexibility of the MP568C.

Just insert your favourite Colour Module and transform the MP568C into fully functional Vintage Mic Preamp!

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.

High-Quality Studio Grade Direct Input

Discrete Direct Input is suitable for a wide range of instruments such as acoustic guitar, electric guitar, bass guitar, synths and any other signal source.

The MP568C Active Infinity Impedance Direct Input is ideal for acoustic instruments like Double-bass, usually equipped with piezo pickups.

No more thin sound! The low-end will be reproduced down to the lowest note!

Optimised Gain Control

The Gain control is optimised for using the Colour Modules. The gain range up to +40dB covers the majority of the gain knob scale.

Such a solution allows better control of the saturation or drive of the colour modules. It also helps in recordings with condenser microphones.

It requires a little bit of practice and sometimes changing the habits to use the Colour Preamps.

More information about using the Colour Preamps and Colour Modules are in the User Manual.
