Knif Audio Eksa Standard with gain+filters

The Knif Audio Eksa Standard with Gain+Filters is a dual-channel mastering analogue EQ with a dedicated filter and gain section, epitomising the zenith of sound purity. Unlike Knif's usual tube-based offerings, Eksa utilises custom-designed class A discrete Op-amps crafted in-house for unparalleled sound fidelity. This device is the quintessential counterpart to the Soma, renowned for its sound beautification. In contrast, Eksa offers unmatched precision, a broad Q value spectrum, and extensive frequency options.

The Knif Audio Eksa is inspired by the legendary Sontec designs. Yet, its Q circuitry is significantly more sophisticated, allowing for independent control over noise and gain across the entire range, irrespective of the Q setting. 

Within the Eksa are 24 discrete operational amplifiers, each featuring JFET inputs and outputs and operating consistently in class A. The configuration includes two OP amps for the primary signal path and two additional ones for each band in every channel. Moreover, it employs DC servos for each band and the core amplifiers, meticulously calibrated to minimise their impact on the audio range. The servos boast extended time constants exceeding one minute and incorporate high-calibre OP amps and polypropylene capacitors to enhance performance. As is customary in Knif equipment, Elma rotary switches replace potentiometers, ensuring precise control.

The Eksa's external power supply contributes to its remarkable sound profile, characterized by unparalleled transparency and accuracy, yet devoid of harshness – a quality that inspired its name, derived from 'exact'.
