Arturia 2.6 manual Type Frequency Audio Output FM Inputs, Mod. Width input

Unlike the low-pass 904A filter, the high-pass 904B filter does not possess resonance. The cut- off frequency can be set with the rotating “frequency” dial or by the 3 modulation inputs which function in the same manner as the inputs of the low-pass.

The following image represents the spectrum of a high-pass filter with a cut-off frequency of 500 Hz.

The 24dB band pass filter resembles the Moog 904C filter, but the difference from it is that while the Moog 904C is a pairing of the 2 associated low-pass and high-pass filters, this one is independent of the 2 other filters. The central frequency can be set with the rotating “Frequency” button, the bandwidth, of 1/3 octave to 3 octaves with the “Resonance” knob. The
