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 nega- tive 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.
