The Omni Filter takes 4 filter sections and rewires them into the 
4 common modes using solid state switches. The solid state 
switches will switch VERY fast, so you can switch them at an 
ultrasonic rate. This is the equivalent of making them behave like 
VCAs. In the between settings (more than one mode light on) 
they are crossfading between filter modes. This was done in 
order to fit the 20 VCAs needed into the enclosure.

The switching frequency is 44.1 Khz. To avoid aliasing 
(ultrasonic ring modulation) there are 24 dB/Octave 20 Khz guard 
filters on the input and output. At least in theory, the entire system 
should be linear and will not produce distortion unless the Q 
control is up. Q is actually regeneration, or taking the output and 
mixing it in with the input (Regeneration would not fit on the 
panel). Since you are adding the output back into the input, this 
produces gain which can lead to distortion (clipping).
