3 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.
