3 Basics of Equalization
The "Hidden" Modes
There are a couple of sub-levels of operation that can be accessed
by pressing different buttons. We covered a number of modes on
the preceding pages; here are two more “hidden” modes:
Demonstration mode
Sometimes it’s fun to have a lot of little lights flashing from the
stage or in the studio. The DEQ830 has a special key combination
that will activate a “fireworks display” for the entertainment of
your clients, audience, or children. In this mode the DEQ830
automatically cycles through the first 25 programs at a rate of 1
per second. To begin the pyrotechnics, first make sure you are in
Program mode. Once you are, simultaneously press the
[UTILITY] button and the [CHANNEL SELECT] button for
Channel 6.
To help prevent an accidental exit from Demonstration mode, only
a few controls are active in this mode. The [MONITOR
SELECT], [BYPASS] and [BYPASS ALL] buttons work the
same way they do in Program mode (audio is bypassed by default).
The [CHANNEL SELECT] buttons can be used to switch
channels.
To exit Demonstration mode, press the [PROGRAM] button.
Lock mode
To access Lock mode, first you must turn off the DEQ830. Then
turn the unit back on, wait until you see the letters “DEQ830” in
the display, and then hold down the [UTILITY] button. After a
couple of seconds you will see the word "Lock" appear in large
letters above the [BAND SELECT] buttons. This mode allows
you to do one simple thing—lock the DEQ830’s controls. To do
this, use the [VALUE] encoder to select “On” for the Lock
function. Default is “Off,” of course.
This function enables you to choose a particular program as the
only one that can be selected once the DEQ830 is powered on.
After this has been done, pressing any button besides the
[POWER] button will cause the Numerical LED Display to show
“Lo” for “locked.” This is handy for environments in which the
DEQ830 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.
B
efore 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
p
rogram you are “stuck”
with when you turn the unit
back on after enabling the
L
ock
f
eature.
It's simple to restore the DEQ830 to full functionality (i.e.,
“unlock” it). Just turn the unit off and power it up in Lock mode
again (turn the unit on and then hold the [UTILITY] button).
Then use the encoder to turn this feature off. The next time you
power up the DEQ830, it will operate normally.
