Base width fader: Here you can set the base width between 0 and 200. 0 means mono,
100 corresponds to an unchanged base width (stereo) and a value of 200 corresponds to
the maximum base width (differential signal).
Depending on the correlation between left and right, an increase in the level when reducing
the base width may come about. In more extreme cases it can bring about maximum
correlation, which then occurs when the left and right channels are identical. And when the
base width is set to zero (mono), a level increase by 3 dB will occur.
Raising the bandwidth (values over 100) diminishes the mono compatibility. If the base
width is reduced, mono compatibility is maintained.
Panorama controller: Here you can adjust the individual channels of the panorama.
Dampening for left and right is displayed above the controller in dB.
If the direction pan mode is active, the controllers operate as direction mixers. In this case
only the mono part (mid signal) is accounted for.
Filter setting parameters
Separation frequencies: With the two sliders "1" and "2" you can adjust the separation
frequencies of the three filter bands. The values are displayed in kHz (they correspond with
the intersection of the neighboring frequency curves).
Band separation: These parameters are used to influence different filter properties to
increase "precision". You have the choice between "Low", "Normal", and "High".
Increasing the band separation setting has the following effect:
• The edge steepness of the filter curves increases and the transition range between two
bands decreases.
• Dampening in the stop band increases (setting low: ca. 25-35 dB, normal: ca. 35-45 dB,
high ca. 55-75 dB).
• The ripple of the frequency range of the bands decreases. However, this is not a
problem as the ripple of the individual filter bands compensate each other when put
together thanks to the complementary filter technology. In any case the output signal
does not contain ripples.
The Multiband Stereo Enhancer in the master area of the mixer:
In the master area of the mixer you have access to the stereo enhancer by pressing the
"StE" button which can be found above the master faders. By right-clicking on this button,
the dialog window of the stereo enhancer will open. The knob next to it is connected to the
base width controller of the mid band.
If "Multi-band" mode is not active in the dialog, the changes affect the entire signal. The
knob then functions as a standard base width fader.
