Pressing ALL ACTIVATED deactivates all filters. The current
status is stored when pres- sing ALL ACTIVATED while a single
or several filters have been deactivated by marking the OFF
option in the according checkbox. Pressing this button once
again, e.g. activating the graphic equalizer, resets the formerly
stored state.

Q
Switching the graphic equalizer’s type between
SYMMETRICAL Q, PROPORTIONAL Q and CONSTANT Q.
SYMMETRICAL Q: The filters have an identical Q at all
accentuation settings. The lowering frequency responses are
symmetrical to the accentuation frequency responses.
PROPORTIONAL Q: A Filter’s Q increases as soon as
accentuation or lowering of the filter increases, with the
effect that the equalizer becomes ”sharper” with increased
EQ setting. The quality defined by Q corresponds to the
quality at full accentuation or lowering.
CONSTANT Q: The filter has the same Q at all accentuation or
lowering settings. The resulting accentuation or lowering
frequency response is not symmetrical.
0.7
0.4...40.0
Q set the quality of all EQ bands. A high Q value results in a
narrowband filter. A low Q value results in a wideband filter.
The fixed frequencies of EQ bands
Sets level amplification (accentuation) or reduction
(lowering) of a band. A band’s fader is indicated in red when
the band has been deactivated by marking the checkbox OFF.
Pressing the spacebar resets the currently selected fader to 0
dB.
Deactivating every single EQ-Band is possible by setting this
checkbox. Deactivating a band does not change the band’s
previously made settings.
Freely programmable LF FILTER and HF FILTER are provided
next to the 10, 15 or 31 bands.
PEQ

His- helv,

TYPE defines the desired LF FILTER or HF FILTER filter type.
PEQ is a parametric Peak-Dip-Filter with programmable
frequency, quality 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.
All pass is a filter which only affects the phase but not the
frequency response of the transmission function.
