The FABRIC Harmonics Generator

In addition to the tape emulator, the ST552 is equipped with HRK proprietary FABRIC harmonics generator.

The FABRIC adds the combination of 2nd and 3rd harmonics to enhance the results of the tape emulator circuitry.

The BLUE mode produces transformer-like harmonics and if used in a moderate amount it will add a magic touch to your tracks.

The RED mode is flat and amplifies midrange harmonics producing the tonal response of a mixing desk.

Each mode can be used creatively to achieve unconventional tonal results.

HRK Active Transformer

Bart Hrk developed the propitiatory design of an Active Transformer to solve the problems of the common passive transformers.

Passive transformers are susceptible to electromagnetic interferences (50Hz Hum, RF Smog) and the frequency response dependents on load and source impedance, negatively influencing the overall performance of analogue studio equipment.

The HRK Active Transformer delivers the sound that we love, including the harmonics content and the tonal response, and removes all the hassles associated with passive transformers.

The Active Transformer produces a subtle “Air” effect and provides extended LF performance.

The Active Transfomer saturation depends on the output level. Higher output signal levels will saturate the Active Transfomer more, like in the classic studio equipment.

7 Days Return Policy

 
Our return policy is a part of the general Terms & Conditions, which you must acknowledge at the checkout. We stand for fair rules and a win-win approach.
We understand that our customers may wish to return the product, and we provide such an option.
 
However, because we are a small company, we can’t afford to run a grade B outlet shop like big distributors and providing the 30 days return period. We can’t also scrap every returned unit.
 
We could charge our customers more to offset the cost of the returns, and this is what major distributors do. Or we can keep our prices low and hope that our customers will appreciate our policy.
 
This is why we provide the 7 days test period after receiving the package with the ordered items. If you wish to return the item, we will accept the return request, providing that the item is not damaged.
 

If the item is damaged during the transport, we will do our best to help you and provide the replacement product.
