The Output Filters are color coded to show what channel is being adjusted. You can also enter the data in various ways. You can adjust the filters based on the other controls on the form or by dragging within the graph itself. Both the information blocks at the bottom as well as the graph itself can be clicked on and parameters dragged where needed.
Pressing this button will place the Input EQ, Crossover, and Output EQ response curves on the graph. These additional curves still respect the access and protection status of other processing blocks. These curves will not be modified by any of the settings on this page, they are simply for reference.
The Flat button returns all of the filters in on this form to their default values.
The Restore button returns the values of all filters to their previous values before activating the Flat button. If you have made a change to the filters, selecting "Restore" will return the values to the settings before the Flat button was pressed. This action will result in the loss of any changes.
The On/Off button in the upper left corner of the panel allows one to turn on or off the entire processing block and the filters.
This selector control allows you to decide what filter is currently being edited using the Filter Controls.Filter Type
This button turns the selected filter on or off.
This drop down list is populated with the type of filters that are available. The list defaults to being a Parametric EQ and will be sorted as indicated below:
Parametric EQ
Low Pass EQ
Low Pass Shelf (6dB/octave)
Low Pass Shelf EQ
Low Pass Butterworth (6dB/octave)
High Pass EQ
High Pass Shelf (6dB/octave)
High Pass Shelf EQ
High Pass Butterworth (6dB/octave)
This numeric spin box allows for the frequency to be set in single cycle steps across a range from 20Hz to 20kHz. The control allows for entering the data in numeric form (13000 Hz) or a number with units form (13kHz)
This numeric spin control allows for the amount of gain to be set between -24dB and +24dB with a step size of 0.1dB. The default value is 0dB.
This numeric spin control allows for the entry of the bandwidth value. This control follows the display mode set by the user preferences of either being displayed in Q or Octaves.
This button disables the selected filter and resets all the parameters for the filter to the default values.
