HSE Audio writes. “We are glad to introduce the Variable Equalizer (VAREQ) option. Both, the VAREQ top plate and the EQ circuit can be integrated in 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 which do not have a 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 makes a precise linearization control possible. Every LP can be de-emphasized to compensate for the RIAA curve. This high precision passive filter makes it possible to manually adjust for optimal performance.
The high precision is possible thanks to the filter which is made from a total of 88 high quality metalized film polypropylene WIMA capacitors and 4 high quality class A gain stages. Long life is guaranteed thanks to the 4 ELMA rotary switches.”
