We are glad to introduce the Variable Equalizer (VAREQ) option. Both the VAREQ top plate and the EQ circuit can be integrated into the HSE Phono Preamp Masterline 7 (ML-7), where only the highest quality handmade Swiss components are utilized.

Thanks to the newly integrated variable equalizer, a more accurate reproduction of LPs that do not have RIAA filtering is possible. The new option can optimize all your recordings. You can now choose between 12 roll-off and 12 turnover positions per channel to find the very best sounding position.

The true-balanced Class A equalizer enables precise linearization control. Every LP can be de-emphasized to compensate for the RIAA curve. This high-precision passive filter allows manual adjustment for optimum performance.

The high precision is achieved through a filter made from a total of 88 high-quality metallized film polypropylene WIMA capacitors and 4 high-quality Class A gain stages. Long service life is ensured by the 4 ELMA rotary switches.
