3 Basics of Equalization

Basic operation: Edit mode

If you're not already there, exit to Program mode by using the [LINK/EXIT] button. Then select program 00 on the DEQ230 by pressing the [DOWN] and [UP] buttons at the same time.

Program 00 is a "flat" program, and it's easy to see why it's called that: the gain setting for every band is 0 dB. Calling up this program is almost the same as pressing the Bypass button, in that the audio passing through the unit will not be equalized in any way. Of course, the difference is that you can edit the program and hear the changes that you make. If you don't already know what kind of EQ you're looking for, this may be a good place to start.

Single Band Edit

Pressing a [BAND SELECT] button puts the DEQ230 into Edit mode. The Numeric LED Display will change from the current program number to the gain value in decibels (dB) of the band you just selected. In addition, one of the Band Gain LEDs above that [BAND SELECT] button will start blinking. If the gain value of that band is 0 dB, the green LED will blink. This means there is no gain change occurring in this frequency range. If it is higher or lower than that, one of the yellow LEDs will blink. This indicates that some amount of cut or boost is happening.

Use the [DOWN/UP] buttons to change the gain value of that band. The [DOWN] button will lower the gain value, or "cut" the chosen frequency; the [UP] button will raise the gain value, or "boost" the frequency. Pressing both the [DOWN] and [UP] buttons at the same time will reset the gain value of the frequency to 0dB. There is an overall range of +/- 12 dB of gain change available.

Band Solo

The DEQ230 has a handy feature called Band Solo that allows you to “isolate” a given frequency while you are editing. This can help you determine exactly which band you need to highlight or de- emphasize. It’s simple to do:

1.Select a band by pressing and holding its [BAND SELECT] button.

2.Press the [UP] button. You’ll see the LED for that band jump to +12 dB.

3.Press the [DOWN] button. The LED for that band will jump to –12 dB.

4.Release the [BAND SELECT] button and the value of that band will be unchanged.

This only works with one band at a time, but you’ll find it to be a very helpful feature.

To exit Edit mode, press the [LINK/EXIT] button. This will return the DEQ230 to Program mode. The same thing will happen if you de-select the single band you have selected.

Use Program 00 if you want to start with a “clean slate” and build a new program from the ground up.

If the Numeric LED Display shows “Li” when you press [BAND SELECT] buttons on Channel B, it means the channels are linked. Either make the edits on Channel A, or return to Program mode and press [LINK/EXIT] to unlink the channels.

After resetting a band’s value, you can change the level of that band in 2 dB increments if you hold one of the [DOWN/UP] buttons and press the opposite button repeatedly. This can help you set up a curve with greater accuracy and speed.
