K6501 // PHILTER

Eurorack Multi-mode Filter Inspired by PHENOL - 8HP

The incredible success of the

has created a buzz amongst Eurorack users. After being asked many times
whether we would release any parts of PHENOL for Eurorack, we finally
created the K6501 PHILTER, inspired by the amazing filters on PHENOL!
Offering the fat punchy sound and dirty overdrive when the resonance
setting is high, the PHILTER is redesigned to work with Eurorack
systems. It offers low-pass, band-pass and high-pass outputs
simultaneously. Each output contains a signal indicator showing when
that output is active. PHILTER has the same tone and range of control as
the PHENOL filters in a compact package.

Although it's only 8HP and looks quite tame, don't be fooled!
The sound and tone colour is completely massive! PHILTER will take even
the tamest sounding oscillators and make them completely explode. Try it
with drum loops and other sounds, or just run your whole mix through a
pair of them!
