Alesis DEQ830 manual Limits of Relative Gain

Page 41

Basics of Equalization 3

One important note, though: Proportional Gain Memory is only temporary. If you run one or more bands “past” the +/-12 dB limit and then you exit Edit mode for any reason (such as to store the program), the gain value of those bands will be remembered as +/-12 dB (whichever was the value that was last reached for those bands).

The limits of Relative Gain

There will be times when the Relative Gain display will not go all of the way up or down to a value of 24. This is because the DEQ830 takes into account the gain setting of all of the bands when an Edit Group is formed. If the highest gain setting of any band in the Edit Group is + 6 dB, then from there down to -12 dB is only 18 dB. So this is the largest number you will see in the Relative Gain display if you run the relative gain value all the way down (see fig. 3 and 4).
