Pure Analog Signal Path
Great care has been taken in engineering the K-2 MK II, including the true to the original VCO, VCF and VCA designs and pure analog circuitry with matched transistors and JFETs. This highly-focused attention to detail is what gives K-2 MK II its ultra-flexible sound shaping capability, which covers everything from super-fat bass and lead tones to stunning effects – all the way out to the otherworldly sounds of your imagination.
Versatile VCF
The very heart of K-2 MK II’s sound is its versatile 6 dB High/12 dB Low filter. The high-pass filter sets the level of signals below the cutoff frequency, effectively reducing the fundamental and lower-order harmonics levels. The low-pass filter controls the level of signals above the cutoff, which reduces higher-order harmonic content. K-2 MK II’s VCF Peak controls provide emphasis to the signals at the crossover frequency.
