Basics of Equalization 3
Remember that a non-primary channel is “mirroring” the settings
of the primary channel. When you perform an edit on a non-
primary channel, you aren’t actually editing that channel; you are
actually changing the primary channe, and the audio for all linked
channels will be affected by the edit. But whatever settings existed
on the non-primary channel before it was linked will still be there
when you unlink it.
To find out which channel is the primary channel in a Link Group,
press and hold the [LINK] button. The Channel Number LED
for the primary channel will flash.

Basic operation: Real Time Analyzer mode
When you enter Save Curve
mode, RTA mode is exited.
When you finish saving the
curve, you have to re-enter
R
TA mode manually.
The DEQ830 is capable of a “light show” that is even more useful
than it is entertaining. Real Time Analyzer (RTA) mode uses the
Band Gain LEDs to show you exactly which frequencies are
present in the audio signal that is passing through the DEQ830.
This is an extremely useful tool that has been a mainstay of serious
sound reinforcement engineers for decades.
To enter RTA mode, simply press the [RTA] button located above
the [POWER] button. Immediately, the DEQ830 will start giving
you visual feedback as to what is going on with the instrument or
mix that is being processed. RTA mode can show you the
frequencies present in the signal either before or after the signal is
processed. To select which you want to see, use the [MONITOR
SELECT] button, located above the [BYPASS] buttons, to toggle
between Input and Output. The green LEDs above the button
will indicate what you are seeing.
[
BYPASS] and [ALL] work
the same in RTA mode as
they do in Program mode.
When you hit one of these
buttons, the Bypass status of
the channels will change as
described on pages 28 and
29.
If you press a [CHANNEL SELECT] button while in RTA
mode, the unit will remain in RTA mode, and the Band Gain
LEDs will show the audio going through that channel. By
switching channels while in RTA mode, you will get a better
picture of what’s going on with the mix.
I
f you were in Program mode
when you entered RTA mode,
turning the [VALUE]
encoder will change the
p
rogram number and the
D
EQ830 will exit RTA mode.
I
f you were in Edit mode
when you entered RTA mode,
the encoder will edit the
bands you had selected.
To exit Real Time Analyzer mode, simply tap the [RTA] button..
Using the [VALUE] encoder in RTA mode
The response of the [VALUE] encoder is determined by the state
the DEQ830 was in prior to pressing the [RTA] button. It might
help to think of RTA mode as a “submode” for whatever mode
the unit was in before you put it into RTA mode. If you had
selected an Edit Group and then entered RTA mode, the Edit
Group remains active. This is extremely useful, as you can see the
changes you are making to the sound as you turn the encoder! But
if you were in Program mode first, i.e., if you had simply been
scrolling through programs before you pressed the [RTA] button,
then the function of the [VALUE] encoder at that point was, and
remains, program selection. So be careful! Turning the [VALUE]
encoder can cause the DEQ830 to exit RTA mode and select
another program.
