Filters are paramount in shaping the tone of your 
sound. While an oscillator’s waveform determines the 
harmonic content of a raw wave, it is the filter that 
allows that harmonic content to be shaped, sculpted, 
and modulated over time to create something truly 
unique.
Matriarch’s filters operate in one of three selectable 
modes; Series, Parallel, or Stereo. Depending on the 
current setting of the FILTER MODE switch, VCF 1 has 
the ability to operate in either High Pass or Low Pass 
mode, while VCF 2 maintains its Low Pass operation 
at all times.
NOTE: A stereo signal path is available from the filters onward.
MODULE PROVENANCE: Matriarch’s filters are based on the 
classic Moog 904A module.
