Basics of Equalization 3

Description of the Basic Modes

Program mode

When this manual refers to Program mode, we mean the very top level of functionality of the DEQ230. Program mode is where you are when it is possible to use the [DOWN/UP] buttons to select between the different programs that reside in the unit. In this mode, you have access to the 30 Preset programs and 30 User programs.

A Program consists of all of the settings on the front panel, with the exception of the status of the [BYPASS] button. The things stored in memory and recalled when you select a program are:

•The gain settings of all 30 bands for both channel A and channel B

•The status of the [LINK/EXIT] button

•The gain settings for all 30 bands of channel B, even if the Link function is active. They are merely "hidden" by the Link function.

•The individual Channel Level settings for channels A and B

If the DEQ230 has been in some other mode, pushing the [LINK/EXIT] button will return it to Program mode. If you see a dot to the right of the Program number LEDs, that means the program has been edited. Be certain to save any changes you've made that you would like to keep! To learn how to Store an edited program, turn to page 38.

Edit mode

While in Program mode, if you push one of the [BAND SELECT] buttons the unit will enter Edit mode. You can tell you are in Edit mode when you see one or more of the LEDs above the [BAND SELECT] buttons blinking. Whichever bands have a blinking LED are the ones that will be boosted or cut when you use the [DOWN] and [UP] buttons.

After you have edited a frequency or an Edit Group (a group of frequencies), if you push the [LINK/EXIT] button you will be returned to Program mode. If you made any changes, you will see a dot to the right of the Program number LEDs. But be certain to save any changes you've made that you would like to keep! That is where Store mode comes in.

Pressing the [DOWN/UP] buttons at the same time will reset the band you have selected to 0 dB.

Store mode

Pressing the [STORE] button takes you into Store mode. From here you can decide which of the 30 User Programs will become the new location for the edited program. You may also instruct the DEQ230 to copy the settings from Channel A to Channel B during the Store process. For information on how to perform either of these procedures, see page 38.
