Link Frequency Sliders
Checkbox:
When checked, this feature links the 20 slider controls together such that
when any one of them is moved, all others move together in sync.
Uncheck the box to move the sliders without affecting the others.
Center Frequency: Note that the Center Frequency of each band is labelled underneath each
slider, and that bands are more closely spaced at low frequencies
Gain Indication: Above each slider control, the gain for that frequency band is given. The
gain can also be visualized graphically by the position of the slider control.
Normalize Button: This button instantly shifts all slider controls up together until the top
slider is at 0dB. After normalization, the relative positioning of the sliders
remains the same. This allows the digital equalizer to implement the
desired equalization curve with minimum signal loss.
Zero All Button: This button instantly moves the slider controls for all bands to 0dB,
defeating the entire equalizer. This is a useful feature when it is desired to
reset all sliders from scratch.
Maximize All Button: This button instantly moves the slider controls for all bands to -40dB,
maximizing the attenuation for all bands. This is a useful feature when it is
desired to quickly adjust the sliders such that only a few bands are passed
with all others rejected.
All Down 1dB Button: This button shifts all sliders down by 1dB from their current position; no
slider, however, will be allowed to go below -40dB. This button allows
the user to shift the entire equalizer curve down so that there will be room
to move one or more sliders up relative to the others.
Store Button: This button allows the user to store a slider configuration to a user-
specified disk file that will not be l
ost when the computer is turned off.
Clicking this button brings up the dialog shown in Figure 3-12 of Chapter
3: .0. Save the configuration to any specified filename; clicking the Cancel
button exits the Store window without storing the slider configuration in
any of the memories.
Recall Button: This button allows the user to recall a previously stored slider
configuration from any of the saved disk files previously generated using
the Store button. Clicking this button brings up the window given in
Figure 3-13 of Chapter 3: .0.
Note: The curve that is in memory prior to recalling any specified file
EXCEPT the one named “Previous Filter Settings” will be stored in
“Previous Filter Settings” as part of the recall operation. Therefore, you
can reload the previous curve at any time by recalling the “Previous Filter
Settings” file.
