One important note, though; Proportional Gain Memory is only
temporary. If you have 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
DEQ230 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).
