Excerpt from the description text of the operating instructions

Theoretically, the distortion in this circuit can be reduced to zero, because on the output side only the output stage equalization demodulated and connected. The dynamic characteristics are improved because the signal is not fed back to the input, which achieves high-speed signal transmission. (Rising speed +-350 V/µs)

Conventional LF and CR equalizers have been developed into high-quality "broadband equalizers" and a high noise ratio has been ensured as a result. Furthermore, the deviation from the RIAA curve in the frequency range from 20 Hz to 100 Hz is only +-0.2 dB.

The circuit design has been simplified by the use of a direct DC servo circuit. As a result, the large decoupling capacitors, which caused equalization from the beginning to the end, were completely replaced, and the device thus became a real direct amplifier capable of reproducing real music signals."
