GAIN TRIM allows increasing the level of the
corresponding channel by up to 6 dB or lowering it
by up to 30 dB to allow level adjustment among
individual frequency bands.

The POLARITY parameter offers the possibility to
invert a channels audio signal, i.e. to rotate its
phase by 180°. Inverting the signal may become
necessary for some specific crossover settings to
eliminate the risk of sound cancellation at the
crossover frequency. The effect of the polarity
parameter becomes obvious when displaying the
summed signal of the two amplifier channels
(switch set to Sum).

DELAY allows delaying the audio signal of the
corresponding output by an adjustable period of
time.
This delay method is typically used as time-
alignment-delay to overcome negative sound effects
like they result from different distances between
loudspeaker systems within one cabinet or the
positioning of speakers in a PA-installation that
otherwise would cause a high amount of natural
delay.
BYPASS allows activating (button not engaged) or
deactivating (button engaged) the corresponding
delay.

Entering the actual ambient temperature is possible here.
In case you have chosen a distance value as unit of
measurement for the delay, delay times are corrected in
relation to temperature. Temperatures can be entered as
°C or °F.
Editing X-Over Filters by Dragging the Mouse in the Graphics Display
Active X-Over filters (Response not set to thru) are indicated by a white dot on the frequency response curve, which
represents the corresponding filter. A click with the left mouse button onto this dot and keeping the mouse button
pressed down lets you set the frequency of the corresponding filter by moving the mouse to the left or the right.
A filter’s title lights in color as soon as the mouse cursor is positioned on top of the corresponding white dot to provide
improved overview and handling. An extra white graph is displayed in addition, representing the frequency response of
the corresponding selected filter.
