Description
Switch for selecting output A or B for filter editing.
A click with the right mouse button opens the ”Copy & Paste” menu, which allows convenient copying all
EQs of the corresponding output to any other RCM-28 Output EQ-filter bank within the same project.

TYPE defines the filter type.
PEQ is a parametric Peak-Dip-Filter with programmable frequency, Q and
gain.
Loshelv / Hishelv creates a low shelving respectively high shelving equalizer
with the following editable parameters: frequency, slope and gain.
Lopass / Hipass creates low pass respectively high pass filters with
adjustable frequency, slope and Q.
Allpass is a filter which only affects the phase but not the frequency
response of the transmission function.

SLOPE sets the steepness or filter-order of low or high shelving equalizers
and low or high pass filters. Setting different slopes within the transmission
range is possible.

FREQ (frequency) sets the center frequency of a parametric EQ or the cut-off
frequency of shelving and Hi / Lo pass filters.

Q defines the quality or bandwidth of a parametric EQ. A high Q-value results
in a narrowband filter, while a small Q-value results in a broadband filter. The
Q-value also sets the quality and thus the response of Hi, Lo and All pass
filters with slopes of 12dB/oct..
0 dB
-18 to +12 dB GAIN defines the amplification (increase) or attenuation (reduction) of
parametric EQs or low shelving and high shelving equalizers.

ORDER (only available with All pass filters) sets the desired filter order of an
All pass filter. A 1st order All pass filter rotates the phase by 180°, a 2nd
order All pass filter rotates the phase by 360°.
