LinPlug CrX4 - Manual (Page 27)

The Filter Envelope section is located below the just described filter
parameters and is working just like any other envelope (see chapter
Modulation / Envelopes).
Each filter also has its own pan (Panning or Panorama) dial. This is used to
position the filter's output signal within the stereo field.
Finally the balance of the filters output volume can be adjusted with the bal
(Balance) dial which is located in the middle between filter 1 and 2.
Left of the pan dial is the parallel/serial switch. It allows to operate the CrX4
filters in either parallel (two parallel, independent routes for audio from the
generators) or serial (where the output from the first filter is connected to
the input of the second filter).
Please note that even in serial the generators allow
to balance their output between filter 1 and 2. Also,
when in serial, the bal (Balance) parameter of the
filter has no effect and is disabled.
In Parallel the output from Filter 1 is sent to Effect 1
and the output from Filter 2 is sent to Effect 2. The
outputs of Effect 1 and 2 are then merged into the
input of Effect 3.
In Serial all Effects units operate in serial too. So the output of Filter 2 goes
into Effect 1, the output of Effect 1 in Effect 2 and so on. This is illustrated
on the setup page (see lower left of the setup page):
