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 Mini-Moog 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
