Basics of Equalization

Description of the Controls

There are thirty buttons side-by-side on each channel of the
DEQ230. These are the [BAND SELECT] buttons. Above each
button is a number like "25" or "8k." These stand for the audio
frequencies, measured in Hertz (Hz), which are selected for editing
by the [BAND SELECT] buttons below them.
Situated between the [BAND SELECT] buttons for Channel A
and Channel B you will find three larger buttons. The one in the
very middle is the [POWER] button. On either side of that are
the [DOWN] and [UP] buttons, which are used to edit the gain
amount of the frequency you have selected with the [BAND
SELECT] buttons. (It is also possible to select and edit several
frequencies at once; more about this later.) The [DOWN/UP]
buttons are also used to select programs in Program mode.
Directly above these three buttons are three more buttons: the
[BYPASS], [STORE], and [LINK/EXIT] buttons. Their
functions are as follows:
[BYPASS]
When this button is first pressed, a red LED will light. This means
the DEQ230 is in Bypass mode. As long as this LED is lit,
incoming audio will pass through the unit without being affected
by the DEQ230. This is useful for comparing the "equalized"
signal with the original signal so you can decide if you like the edit
you made. Press the button again to get out of Bypass mode and
hear the effect.
[STORE]
Once you have made an edit you would like to keep, press this
button to enter Store mode. From there you can decide which of
the 30 User locations will become the new home for the edited
Program. You can also copy the settings from Channel A to
Channel B as you store a program. For more information on this
function, see page 38.
[LINK/EXIT]
This button serves a dual purpose:
1. While in Program mode, pressing this button will cause the
settings for Channel B to "mirror" the settings for Channel A.
Any further edits you make to a band on Channel A will also
happen to that same band on Channel B. This is useful for
quickly setting up a program without having to make
independent adjustments for each channel.
2. If you're in the middle of some other activity, such as editing
or storing, pressing this button will allow you to "exit" to
Program mode.

Bypass mode "hides" the
effect the EQ and Channel
Level controls have on the
audio. However, the Master
Level function from Setup
mode is unaffected by the
[BYPASS] button. For more
information about the
relationship between Channel
Level and Master Level, see
page 45.
It is possible to copy the
settings from Channel A to
Channel B during the Store
process so they are not merely
"mirrored." See page 39 for
further details.
