OUTPUT PARAMETRIC EQ
All output channels employ 6-band parametric equalizers each, mainly for speaker equalization. Except for the
possibility to select ”All pass” as filter type, these filters are identical to the ones of the input EQ's.
Graphics Display Indication
The graphics display offers several different display modes, as described in the following table. Display generally
includes all effects of filters that are located pre Output Parametric EQ, which always provides precise overview and
control of the resulting frequency response at this point.
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 trim settings and therefore graphically
displaying the audible result at the amplifier‘s outputs.
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 indicating measured speaker transfer functions. For this function to be
effective you first have to load speaker data in the ”Speaker” tab.
