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

Signal Descriptions

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

dB, the result is 7dB.

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.
