Low Pass Filter
The 904a from Aion Modular is Eurorack's first real authentic clone of the famous Moog modular low pass filter. It is not to be confused with the Minimoog filter which is a different design. The 904a, while simple in its appearance, just has the classic sound you'd expect from a filter of this heritage.
The Frequency Range switch sets the frequency band in two-octave steps:
1- 1Hz to 5kHz
2- 4Hz to 20kHz
3- 16Hz to 80kHz
