Crossover frequency
See V.2.1and V.1, Controls the crossover
frequency of the low passfilter and the highpass
filter. Notify the frequency multiplier switch(1x
white or 4x red) so Twelve cross over frequency
values can be set,

Hp bypass
Activates or bypasses the highpass filter. see
V.2.1 to V.2.4

Order
This cotrol defines the rollof slope, choose
beteween first order(6dB/oct) of second order
(12dB/oct). The first order filter crossoverpoint
is at -3dB. And the second order filter is -6dB.

Paralell compression
New York compression, mowtown compression
or parralell compression is one or more
compressors working paralell on the same
material and later mixed together. Often, a
heavy compressed signal is combined with an
ligtly or uncompressed signal. The filter bypass
function makes it possible to change from a band
compressor to a set of three stereo
compressors configured in paralell, wich enables
paralell compression.
The bode plot’s in the prevous chapters indicates
that if the machine is set as three paralell
compressors, the order and filter crossover
frequency cotrol has no function, see for
example the right bottom bode plot (V.2.1-V.2.1)

Filter
In general, the filter splits the signal in a low, mid
a high band. furthermore the filter settings
enables the user to enables/bypass filters and
sets the order or bypass all the filters to enable
paralell compression. The next subjects besides
cross over frequency discribes one of the two
filter sections but they work equally.

Lp bypass
Activates or bypasses the lowpass filter, see
V.2.1 to V.2.4
