3 Basics of Equalization

Basic operation: Audition mode

No doubt there will be times when you want to switch back and forth between different programs to determine which one is best suited for the audio source. But as easy as it is to navigate between the DEQ230's programs in Program mode, it's still difficult to focus on what's happening to the audio when you're making sure you land on the right program.

Audition mode provides the solution. It allows you to specify any of the 60 programs within the DEQ230 as members of the Audition List. This is like a series of bookmarks, allowing you to jump over programs that are not intended for a particular audio source and only call up the ones that are.

To enter Audition mode, first be sure the DEQ230 is in Program mode. After that, press and hold the [LINK/EXIT] button and then press the [DOWN] button. You will see four more LEDs light up over one of the [BAND SELECT] buttons, in addition to the Band Gain LEDs that were already lit for the current program. These four LEDs indicate that the [BAND SELECT] button beneath them now represents the active program in the Audition List. You will also see the number of the active program in the Numeric LED Display.

As you know, the DEQ230 has 60 programs. Conveniently, it also has 60 [BAND SELECT] buttons. So in Audition mode the [BAND SELECT] buttons represent a "map" of the Preset and User programs, and are used to select the programs that will be auditioned.

For example, if you entered Audition mode while you were on Preset program 04, then the stack of lit LEDs would be above the 63 Hz band on Channel A. If you want to toggle between that program and Preset program 10, count six [BAND SELECT] buttons to the right and press the 250 Hz button. You will notice that now there are four LEDs lit above the 250 Hz [BAND SELECT] button and only two LEDs lit above the 63 Hz band. As you recall, the four LEDs indicate which of the programs is active. The presence of two lit LEDs indicates that a program is part of the Audition List, but is not currently the active program.

You may add as many programs as you like to the Audition List. If you no longer want a given program to be part of the Audition List, simply press its [BAND SELECT] button again briefly. Its LED will turn off, indicating that this program will be skipped over the next time you cycle through the Audition List.

To exit Audition mode, press the [LINK/EXIT] button again, or deselect all programs from the Audition List.

Be sure to store any edits you want to keep prior to entering Audition mode. The Audition list only uses Preset programs or programs that have been stored to the User locations.

The [BYPASS] button is also available in Audition mode. You can use it to “audition” the original signal manually, or you can use program 00 “Flat” in the Audition list to automate theDEQ230’s return to the unprocessed audio signal.

Remember, the very first program is program 00. So if you want to include program 01 in the Audition list, you will need to select the second [BAND SELECT] button from the left. This is because program 01 is the second program in the DEQ230’s memory.

If you can’t remember what factory curves correspond to each program number, refer to the Program Charts in Chapter 5.

DEQ230, DEQ230D specifications

The Alesis DEQ230 and DEQ230D are sophisticated digital equalizers designed for audio professionals seeking precision in sound control. Equipped with advanced features and innovative technologies, these units cater to a variety of applications, from live performances to studio recordings.
