Knif Audio Eksa 2x2 Channel Vinyl Mastering Edition Equalizer

While drawing inspiration from classic Sontec designs, Eksa extends far beyond traditional architectures. Its advanced topology allows noise performance and wideband gain behavior to remain largely independent of Q settings, ensuring exceptional consistency and clarity.

Eksa includes integrated M/S encoding and decoding and is built around 28 in-house class-A discrete operational amplifiers. Carefully implemented DC servos maintain absolute transparency, with time constants chosen to eliminate any audible influence. Precision relay switching and polypropylene filter capacitors further support wide bandwidth, low noise, and signal integrity.
