At ­800d or lower, input will be muted. If a preset value is recalled, the feedback value can be different from the input. Trim Controls ­ Slot 1, SubSlot 3 TrimBand TrimBand refers to a modification of the gain of the forty graphic filters. 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 = 10dB and Trim = -3dB, 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. 12 · Volume/Equalizer Control Expansion Card: C2VEQ-4 Operations & Installation Guide - DOC. 6136 Crestron C2VEQ-4 Volume/Equalizer Control Expansion Card A TrimBand value of 0 (0dB) means that the signal will pass unaffected. Values above and below 0 boost or reduce the gain in increments of . 1dB. That is, changing the analog value by one signifies a change in boost or attenuation of 0. 1 decibel. The C2VEQ-4 provides ten trim presets, where a trim preset is a set of all forty TrimBand values. On the rising edge of <SaveTrimPreset>, the forty TrimBand values will be stored in the preset specified by <TrimPreset#>. Valid values for <TrimPreset#> range from 1 to 10. On the rising edge of <RecallTrimPreset> the values stored in the indicated <TrimPreset#> will be recalled and propagated to the outputs.
