Applied appropriately, the dierence between loud and soft is reduced without
killing the interesting dynamics in your performance.
The Threshold control sets the singing level at and above which the amount of
gain reduction (compression) specied by the Ratio control will occur. The range is
0 dB to -40 dB: 0 dB being the loudest input signal the Voice Processor can accept
without distortion and -40 dB being a very quiet signal. If you sing consistently
more quietly than the Threshold, you will not hear any compression. A good set-
ting for experimentation is -10 dB.
The Ratio control sets how much gain reduction you prefer when your voice level
goes above the threshold. The range is from 1.0 : 1 (no gain reduction) to 50.0 : 1
and then Inf : 1 (maximum vocal gain reduction ). A good setting where to start
from for Ratio is 4.0 : 1.
The number on the left side of the : (colon) symbol is how loud the peaks in your
singing have to be in order to achieve a 1 dB gain increase. A brief example of how
adjusting the ratio of the compressor works is this: say a word you sang went 4 dB
over the threshold when the Ratio was set to 4.0 : 1. The compressor would only
allow it to go 1 dB louder.
Note that the Ratio control has to be set above 1.0 : 1 to apply any compression
regardless of the setting of the Threshold.
Programing the Gate
Use the Gate if you hear feedback or there are other sounds entering the mic
other than your voice.
A typical, xed gate works by shutting o, or reducing the level of any signal below
a threshold that you set. When you sing louder than that threshold, the gate will
open and your vocal will come through the amplication system. When you aren’t
singing, the gate will close and block sounds around you.
You can also turn the gate to O with good results if you are in a quiet, low volume
musical environment.
