Basics of Equalization 3

Likewise, if the lowest gain setting of any band in this same Edit Group is -4 dB, then the largest number you will see in the Relative Gain display going all the way up is 16 (see fig. 5).

So if you run the Relative Gain display up and down repeatedly with this Edit Group, the display will hit the "ceiling" at 16 and bottom out at 18.

The Release Edit Group function

Once you have changed the value of the Edit Group, the DEQ230 will react one of two ways to further presses of the [BAND SELECT] buttons. To decide which option suits your working method or circumstance, experiment with the setting for the Release Edit Group function in Setup Mode.

If this function is on, the very next [BAND SELECT] button you press after you have changed the level of the Edit Group will "release" all of the previously selected bands. The only band that will be selected is the one you just pressed. You will know this when it happens, because that's the only Band Gain LED that will be blinking.

If the Release Edit Group function is off, the next [BAND SELECT] button you press after you have changed the level of the Edit Group will simply add that band to the Edit Group.

For a more detailed explanation of the Release Edit Group function, see pages 44 and 45.

Remember, if you want to keep the edited program, be sure to store it to one of the User locations. For instructions on how to do this, turn to page 38.
