Basics of Equalization
If the Release Edit Group feature is off, the next [BAND
SELECT] button you press after you have changed the level of
the Edit Group will simply add that band to the Edit Group. The
upside of this is the convenience of being able to edit three
frequencies +3 dB, for example, and then add another frequency
to the pile and edit them all another +2 dB without having to
reselect the first three. The downside is that you will have to
deselect all four bands if you want to grab one more frequency
and edit it by itself.
There are pros and cons to both ways of working. So, experiment
with this feature and see which way works best for you.
To enable or disable the Release Edit Group feature from this
Setup mode page, press one of the [DOWN/UP] buttons.
Button 3: Edit Time Out (on/off)
The Edit Time Out function serves as an "auto-exit" feature.
When it is enabled, if you have not changed the gain value of any
band or Edit Group for 30 seconds, the DEQ224 will exit
automatically to Program mode.
We have included this feature so the DEQ224 can mold itself as
seamlessly as possible into your working style. If you prefer not to
have the unit continue reminding you it is still in Edit mode by
blinking its LEDs, vying for your attention, as it were, with the VU
meters on your mixer, then Edit Time Out is a feature you will
appreciate.
On the other hand, if you prefer to have the DEQ224 remain in
Edit mode so you will not lose your chosen Edit Group when the
unit returns to Program mode, you may want to turn the Edit
Time Out function off.
The default setting for this function is "Off"; to enable it press one
of the [DOWN/UP] buttons.
Button 4: Lock (on/off)
This function enables you to choose a particular program as the
only one that can be selected once the DEQ224 is powered on.
After this has been done, pressing any button besides the
[POWER] button will cause the Numeric LED Display to show
"Lo" for "locked." This is handy for environments in which the
DEQ224 is used for tuning a room, for example, or whenever you
don't want someone calling up a different program, editing the
current program, and/or storing a different program on top of the
one you have created for a particular application.
Before you try this feature, make sure you're happy with the
program you had selected prior to turning the unit off. It will be
the program you are "stuck" with when you turn the unit back on
after enabling the Lock feature.
If you're already in Setup mode, all you have to do to enable this
feature is press the fourth [BAND SELECT] button and then
press one of the [DOWN/UP] buttons. You should see the
