Element Description
Switch for displaying frequency response (magnitude) or phase response (phase)
Switch for scaling the dB-axis to 25 dB (± 12.5 dB) or to 50 dB (± 25 dB)
Displays the resulting transfer function of all filter and level settings and therefore graphically
displaying the audible result at the amplifier‘s out- puts.
The ”Sum” switch causes display of the summed signal of the output channels, including Output
level and Mute. If the ”Sum ” switch is not pressed the output channels’ transfer functions are
indicated separately.
Switch for including programmed delays in the frequency or phase response indication. The delays
mainly affect phase response indication. Indicating the sound system processor channels’ summed
signals reveal very clearly the effect that the delays have on the frequency response, e.g. as notch
filter effect.
Switch for additionally displaying measured speaker transfer functions. For this function to be
effective you first have to load speaker data in the ”Speaker” tab.
Channel Selection

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 Array EQ-filter bank within the same project.
Filter Parameters

Default Range Description
Name of the corresponding filter band.
A click with the right mouse button on this field opens the ”Copy & Paste”
menu, which allows convenient copying all EQ-parameters of the according
filter to any other EQ 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.
6dB/Oct 6dB/Oct, 12dB/
Oct
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.
