c.
Set all values of equalizator to
0Db
.
d.
Set all bands parameters with following value:
1 GAIN :
0 Db
2 ATTACK TIME:
10mS
3 HOLD TIME:
0%
4 RELEASE TIME: 10mS
5 THRESHOLD:
-2Db
6 TRANSITION:
15
7 DRIVE
:
1
You will get a gain of 0dB INPUT = OUTPUT.
Starting at 4.5 / 22Khz, adjust THRESHOLD A -30Db
Set the DRIVE to 10 and decrease the TRANSITION until reaching of the tone pleasing on the
frequencies of the selected band (recommended 4).
Perform the same operations on the other 3 bands going down to the band 1 to make last.
Now the parameters ATTACK TIME, HOLD TIME and RELEASE TIME remain to be adjusted
In order to obtain the result that is more in keeping with one's own transmission requirements, bearing
in mind the graphs of figures 1 and 2.
Figure 1:
1.
ATTACK TIME set at 300mS:
It establishes the time that elapses before the intervention of the
compression to the attack of the sound, in the case shown the initial peaks are allowed to pass, wider
sound dynamics.
2.
RELEASE TIME set to 10mS
: It establishes the time that elapses before the intervention of the
expansion, in the displayed case the expander intervention is very fast making the sound more abrupt.
3.
HOLD TIME: At 50%
of the RELEASE TIME, the intervention of the expansion is less abrupt.
