TrimBand
TrimBand refers to a modification of the gain of the forty graphic filters.
There are ten trim presets. A trim preset is a set of all forty TrimBands. (The
TrimBands are not labeled with actual frequency values since they can be changed in
the Digital Audio Tools or by setting the full parametric filters in the symbol.) Trim
presets can be used to modify the soundfield for different kinds of music where you
might want to emphasize the bass, or bring out a treble frequency.
Programming in SIMPL Windows
Each channel has a set of ten TrimBand inputs. The TrimBand inputs only adjust the
gains of the gain-adjustable filters; thus <TrimBand1-1> corresponds to channel 1,
filter 1; <TrimBand1-2> corresponds to channel 1, filter #2; <TrimBand2-1>
corresponds to channel 2, filter 1, and so forth. The gains are adjustable within a
range of -10dB to +10dB. All TrimBand values propagate immediately to the
outputs. TrimBand values are added to the gain values of the filters. If Gain = 10
and Trim = -3 , the result is 7
dB
Valid values for TrimBand range from -100 (-10dB) to +100 (+10dB). 2-Series
symbols such as the Analog Scaler with I/O Limits and Analog Ramp (Bounds
Limited) can handle range and sign mapping.

VALUE DEFINITION
1/0 Saves current mixer values
on mixer channels 1-4 into
the given MixerPreset#, on
the rising edge of the signal.
1/0 Recalls the current mixer
values on mixer channels 1-4
from the given MixerPreset#
on the rising edge of the
signal.
1 to 5 Five user-definable mixer
presets, each includes all
MixerBands.
0 to –800d (0dB to –80dB) For these
or lower controls of audio outputs 1,
2, 3, and 4, each analog
increment of 1 = 0.1dB.
0 to –800d Feedback immediately
or lower tracks input. At –800d or
lower, input will be muted. If
a preset value is recalled,
the feedback value can be
different from the input.
