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. Here the

<TrimBand#-#_FB> outputs may have different values than the TrimBand inputs

(the only time these values will differ).

If <RecallTrimPreset> goes high and <TrimPreset#> is set to an invalid value (out

of the 1 to 10 range) all trim settings will be cleared, and all signals will pass with

whatever gain setting was in effect. This is the same as recalling a trim preset in

which every TrimBand value is set to 0.

A rising edge of <ClearTrims> will also set all TrimBand values to 0.

The Trim Controls symbol is illustrated below and on the next page; the tables

following the illustrations provide join details.
