Basics of Equalization 3

The "Hidden" Modes

There are several sub-levels of operation that can be accessed

from Program mode by pressing different buttons. We covered

Channel Level mode and Audition mode 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 DEQ230 has a special key combination

that will activate a “light show” for the entertainment of your

clients, audience, or children. To begin the pyrotechnics, first make

sure you are in Program mode. Once you are, hold down the

[LINK/EXIT] button and press the [UP] button.

To exit Demonstration mode, press the [LINK/EXIT] button.

Real-time Analysis mode (DEQ230D only):

The DEQ230D is capable of another “light show” that is even

more useful than it is entertaining. Real-time analysis (RTA) mode

uses the Band Gain LEDs to show you exactly which frequencies

are present in the audio signal that is passing through the

DEQ230D. This is an extremely useful tool that has been a

mainstay of serious sound reinforcement engineers for decades.

To enter RTA mode, press the two leftmost [BAND SELECT]

buttons on Channel A (25 Hz and 31 Hz). Immediately, the

DEQ230D will start giving you visual feedback as to what is going

on with the instrument or mix that is being processed. RTA mode

monitors the outputs of the DEQ230D, so when you press the

[BYPASS] button you will be seeing what you are hearing: the

unprocessed signal.

Metering modes

Like any professional audio product, the DEQ230D allows you to

configure the response of the Band Gain LEDs while in RTA

mode. Use the [DOWN] and [UP] buttons to select between the

four different settings:

00 Peaks are not held.

01 Peaks are held for one second.

02 Peaks are held for two seconds.

Peaks are held until the metering mode is switched

to another setting, or until you exit RTA mode.

If you want to reset the peaks while they are being held in

Momentary 1, Momentary 2, or Continuous settings, press the

[DOWN] and [UP] buttons at the same time.

eing in Demonstration mode

is something like being in

udition mode; the DEQ230

will cycle automatically

through all 60 programs one

after the other. The main

difference is that while in

emonstration mode, the

audio signal is bypassed.

eld peaks may be reset at

any time by pressing the

[

DOWN] and [UP] buttons

simultaneously.

There are two ways to get out

of RTA mode: pressing the

25 Hz and 31.5Hz buttons on

Channel A simultaneously, or

by pressing the [LINK/EXIT]

button.
