Description
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.
Q sets 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. Pres- sing 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.
Press the EQ FLAT button to reset the gain of all filters to 0 dB.
