Element Description
Switches between frequency (magnitude) and phase response (phase) indication
Switch for selecting dB-axis scaling of 25 dB (± 12.5 dB) or 50 dB (± 25 dB)
Channel Selection
Element Description
Switch for selecting input A or input B for filter editing and display.
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 PEQ 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.
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.

Hz
20 Hz to 20 kHz FREQ (frequency) sets the center frequency of a parametric EQ or
the cut-off frequency of shelving and Hi / Lo pass filters.
0.7 0.4 to 40.0
(PEQ), 0.4 to 2.0
(Hi-/Lopass)
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.
