Modular systems already exist, so why the Inherit system?
Modular systems like the 500 are imperfect and like all versatile systems, they do not excel in any one area and are therefore not the ultimate solution for solid state or tube amplification for the ultimate sound seeker. The function of preamps is to process weak signals, so they are very sensitive to electromagnetic interference and require shielding that the foramt 500 cannot provide.

Moreover, the shielding of racks and lunchboxes 500 is not always of very good quality. The Inherit system offers a high quality multiple power supply and an excellent shielding environment.

The concept
The idea behind the Inherit system is to offer an uncompromising mic/instrument preamp, incorporating exceptional components and offering a modular amplification expert. A preamp is the main element for a good sound recording. In an audio chain, it is placed just before the digital conversion. It is therefore by definition analog and not transformable.

Contrary to other modular formats, it allows the implementation of high voltage or high current multi-voltage preamplification technologies. In addition, the lack of space constraints and the improved EMC (electromagnetic compatibility) environment allow for fewer compromises in electronic designs. The result is exceptional audio quality. The preamps available through the Inherit system are simply not available in the 500 format, due to its limitations.

Isolation
The proprietary Inherit format keeps the sensitive part of the electronic design in a one-piece machined cartridge that acts as a Faraday cage to offer optimal electromagnetic shielding performance. and the design allows great convenience for the user is very practical.

Uncompromising sound quality
This is a premium recording preamp for professionals and sound engineers looking for uncompromising results. But although it is primarily dedicated to recording studios, its rugged construction allows for extensive use on tour for FOH engineers who want to use different sound colors without the hassle of carrying multiple racks.

Exclusive characters
When recording, users can quickly and easily compare, for example, the sharpness of a Solid State mic pre with the warmth of a real tube preamp, without having to patch. Some cartridges are designed around proven technologies that are standard in recording studios and others are designed around new, exclusive technologies specific to the Inherit system. The Inherit system will therefore allow you to access complex preamplifiers such as true tube preamplifiers or complex discrete designs that are impossible to obtain with a 500 Series modules.

The Rack
All functions of the Inherit rack are analog, digitally controlled in a highly shielded construction to protect the signal path. This allows each cartridge to retain its unique and unaltered sound.

As for the proven technologies, many improvements have been made to achieve a high signal-to-noise ratio while maintaining the original exceptional behavior and tonal color that made them classics.

The power supply
The rack's custom power supply was designed with great care and contains 7 unique voltages that are generated by three toroidal power transformers.
