External power supply
Overview
Knif Aski is a standalone phono preamplifier compatible for use with either moving magnet or moving coil pickup cartridges. The front end in both input modes is a hybrid op amp consisting of a cascode discrete JFET followed by a state-of-the-art OPA828 IC. The MC input has four parallel connected LSK389 JFETs contributing for lower noise. The JFET input also ensures very low non-linearity of the input capacitance, which is crucial for flawless MM operation.
Aski features RIAA equalization, a multiple of cartridge load options for both inputs, a switchable 20 Hz high-pass filter, and a wide range of gain adjustments. The unit can be powered either from an external power supply or the auxiliary power output in the Knif Mastering Controller power supply.
With its ultra high accuracy, ridiculous headroom, immeasurably low distortion, and very low self noise, the performance of Aski is immaculate.
