Range Meaning

Display area Use the radio buttons ‘ Mag’ or ‘Phase’ to switch the diagram from Cartesian coordinates (level vs.

frequency) to polar coordinates (angle vs. frequency).

Use the radio button ‘SHOW ALL EQ’ to display the parameters for all nine frequency bands.

Control area For each output channel and all nine frequency bands (numbered with ‘PEQ’ ) you can enter the

parameters of the parametric equalizer directly as numerical values in the left part of the window:

Centre frequency, lter quality, slope, lter type. With the ‘Bypass’ button, the equalizer for the

respective frequency band and the respective channel can be bypassed temporarily.

In the middle part of the window ( ‘PEQ Parameter’ ) you can adjust the parameters centre frequency,

lter quality and slew rate with the faders and the arrow keys on the PC keyboard. The setting refers

to the frequency band that is highlighted green in the left part of the window.

When the IIR lter is selected, you can select the cut-o frequency and lter type for the low-pass and

high-pass lters. Use the ‘Bypass’ button to temporarily bypass the lter.

If you select the FIR lter, the PC software displays the FIR coecients. You can select and adjust the

type (low-pass, high-pass, frequency band) and set the cut-o frequency for the high-pass and low-

pass lters. The FIR curve appears with numerous setting options. Here you can select the number of

taps from ‘512’ … ‘1024’ (preset: 512). The FIR lter becomes active when you click [OK]. To import

external FIR coecients, select for ‘TYPE’ ‘External FIR’ and click on the le to be imported (supported

le formats: csv and txt). The imported FIR-PEQ is displayed immediately in the FIR curve.

Drag the fader in the right part of the window using the mouse to set the level for the output channel.

The ‘Mute’ button mutes or unmutes the respective channel. The ‘Normal’ / ‘Inverse’ button inverts

the phase of the respective channel by 180° when needed.
