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 reveals 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.

Switch for selecting output 1, 2, 3, 4. 5 or output 6 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 Dx46 Array
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 and slope.
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..
