This section describes the parameters that can be changed
(edited) in the different modes, and explains how to make
these changes -- in other words, how to edit.
Editing in the AFB Mode
Quick Edit
When you use the AP-700 in the AFB mode, filters are set
manually. You can also use the same procedures to modify
filters set by the Auto function.
* Filters produced by the Dynamic function cannot be modi-
fied.
EDIT >
1. Move the cursor to the filter number and use
the (VALUE) buttons to select the filter number
you wish to modify.

2. Use the cursor buttons to move the cursor to the
parameter you want to work with, and make
the settings with the (VALUE) buttons.
If you modify the parameters for a filter that was set by the
Auto function, the filter number is highlighted (inversed),
indicating that the setting has been modified. Also, when
feedback occurs at the same frequency as a modified filter,
the feedback is eliminated by a different filter set to the
same frequency.
You can repeat steps 1 and 2 fo set the para-
meters for all filters.
* Settings for the filters can also be made in the screen called
up by using the following procedure.
MENU > AFB mode P EDIT P
[FILTER NUMBER] (A1 to Ai8 and M1 to M18)
This selects the filter to be set. The parameters for the cho-
sen filter appear on the display.
A:
Displays a filter set by the Auto function.
M:
Displays a filter toggled on or off by the Manual func-
tion.
* A filter set by the Auto function can be made into a Manual
function filter, and a filter reserved for the Manual function
can also be made into a filter reserved for the Auto func-
tion. This change is made by selecting the filter number to
be changed and pressing [ENTER]. When you do this, a
message asking you to confirm the change appears on the
display. Press [ENTER] to change the Auto or Manual func-
tion. If you want to start over, move the cursor to [CAN-
CEL] and press [ENTER].
If you choose not to make the above change, only the para-
meters will be changed.
(If a change has been made in the reservations, the filters
numbers will be rearranged.)
[FILTER TYPE]
(PEAKING, LOW SHELVING, or HIGH SHELVING)
This selects the type of filter.
PEAKING:
Sets Frequency, Q, and level as a para-
metric type equalizer.
LOW SHELVING:
Sets frequency and level as a low-shelv-
ing type equalizer.
HIGH SHELVING:
Sets frequency and level as a high-shelv-
ing type equalizer.
* The type of a filter reserved for the Auto function is fixed
at "PEAKING" and cannot be changed.
[FREQUENCY] (19.7 Hz to 20.2 kHz)
For a parametric type filter, this sets the center frequency.
With a shelving type filter, this sets the frequency at which
the filter begins to be applied.
[Q] (0.3 to 100)
This sets the range over which the filter is applied, center-
ing on the frequency set with "FREQUENCY."
Larger values for Q result in steeper filter characteristics.
* The Q value for a filter set by the Auto function is set auto-
matically according to the level. However, this parameter
can be used to change the value set for Q.
* The Q value is not displayed when "LOW SHELVING" or
"HIGH SHELVING' is selected for Filter Type.
[LEVEL] (AUTO: -40.0 to 0.0 dB; MANUAL: —40.0 to +12.0 dB)
This sets the filter level (amount of boost or cut).
* Setting the level to "0 dB" clears the filter.
