Editing an EQ Curve
After you make an edit to a
Program, you must save
those changes to one of the
User Program locations. If
you select another Program
before you do, your edited
Program will be lost. For
information on how to save
an edited Program, see the
description of Save mode on
page 20.
Once you are in Edit mode, there are three EQ parameters
available. Use the Parameter Up/Down buttons to select the
one you want to edit, and then use the Value Up/Down
buttons to make an adjustment:
•
Frequency —select a value between 20Hz and
20Khz.
•
Gain —select a value between -12dB and +6.0dB.
Gain Value
TIP: To disable an EQ band,
set its GAIN value to 0 and its
Q to anything but HP.
•
Q —select a value between 0.25 and 4.0 octaves. If
the Value Down button is held, the values will
“race” downward to 0.25 and stop. However, there
are three more values which are accessed by
additional presses of the Value Down button: HSH
(high shelving), LSH (low shelving) HP (high-pass
filter). For definitions of these settings, see page
27.
Note: if a Q value of HP is
selected, the Gain parameter
is not available.
Remember the “double-
button reset” trick: pressing
the Value Up/Down buttons
at the same time will reset the
selected value to its default.

Q Value
The Band button
The Band button
Press the Band button to select which of the four Bands will
be edited. Each has its own Frequency, Gain, and Q
parameter.
To exit Edit mode, hit the Page button twice. Keep in mind
that any changes that were made will be lost if another
Program is selected before the edited Program has been saved.
