15.3 CHOOSING A CURVE
As already explained in other sections of the manual, the DSPs in the processor implement three compressors,
which affect the 3 bands: Bass, Mid and High.
The three meter bars displayed on the front panel indicate the level of compression exerted on each frequency
(in other words, the more notches shown, the more the corresponding frequency is compressed, and thus the
less will be audible).
The curves are identified by three letters: B (i.e Bass), M (i.e. Medium) and H (i.e. High).
The higher the value of a band in respect of the others, the more the band will be present on the output.
Example
:
The curve 02 (B3M0H3) mainly contains Bass and High sound components, as the Medium frequencies are
compressed (as indicated by the ‘0’ index, in respect of B=3 and H=3).
On the other hand, the curve 07 (B3M3H0) contains strongly presence of Bass and Mid frequencies, as High
frequencies are compressed (H=0).
As You can get from the preset table, curves 1, 11, 21; 2, 12, 22; 3, 13, 23, etc have the same ‘ratio’
between Bass, Medium and High frequencies (f.i. Bass level is twice the amount of Medium level, etc) but
the ‘absolute’ level index is higher, meaning that curve’s density is higher.
Example
:
The curve 12 (B6M3H6) presents the same relation between the band levels (i.e.the ‘sound equalization’ is the
same than curve 02) but density has changed: as ‘absolute’ level index are higher than curve 02 (B6 > B3,
M3>M0, etc), curve 12 allows you to reach a higher broadcasting sound level
The preset table provides also, in the last column, an useful classification of curves according to their ‘sound’
(pop, bass, disco, etc).
