COMBINATION EQs 
USING BOTH BANDS

Sometimes it's necessary to treat a
couple of frequency bands simultane-
ously. The Dual Parametric D.I. is per-
fect for this. In some cases, the bands
may be very close together, requiring
fairly narrow bandwidths (setting the
Octave control to less than .5). Here's
the combined response of two bands
boosting frequencies near each other:

Notice that because the bandwidths
can be wide or narrow, they may over-
lap, creating a less pronounced boost
(or cut) between them.
