The ST552 is an Analog Tape Emulator dedicated to professional music producers and studio engineers.

The ST5552 accurately emulates the saturation of the Reel-to-Reel studio recorder adding colour and analog harmonics to your music production.

The 30/15 IPS modes are designed to mimic the LF resonance of the tape at the different feed speeds.

The FABRIC circuitry enhances the results produced by the ST552 Tape Emulator adding the harmonics and the final touch to the processed music material.

The ST552 is easy to use, and intuitive controls make tracking, reamping, or mastering a quick and satisfying job.

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 has developed a proprietary design for an Active Transformer, aimed at addressing the limitations of traditional passive transformers.

Traditional passive transformers are known to be vulnerable to electromagnetic interference, such as 50/60Hz hum and HF RF smog. Additionally, their frequency response is contingent upon load and source impedance, which adversely affects the overall performance of analog studio equipment.

The HRK Active Transformer is a game changer that not only resolves the issues associated with passive transformers but also retains and amplifies the desired characteristics of the transformer output stage. This includes the enrichment of harmonic content and the enhancement of tonal response.

What sets the HRK Active Transformer apart is its ability to deliver the rich, beloved sound that audio enthusiasts seek, including the harmonic content and tonal response, while simultaneously eliminating the drawbacks of passive transformers.
