Audio In/Out, Voice and Guitar Processor

Programming the compressor

This is a compressor optimized for vocals. Be sure to reduce the level of

your amplification when adjusting the compressor, because high settings

can cause more gain and thus feedback.

Compression can be quite subtle until you educate your ears. We typically

sing dynamically, like this (capitals are used to show louder dynamics):

At acoustic singing levels with no, or very quiet instrumentation, this would

sound fine. When amplified however, the loud words become strident and

even worse, quiet words can be lost in the instrument sounds. The louder the

amplification system and band the more pronounced the loud parts become.

Compression seeks to do the following to your dynamics:

Applied appropriately, the difference between loud and soft is reduced with-

out killing the interesting dynamics in your performance.

amount of gain reduction (compression) specified by the Ratio control will

occur. The range is 0 dB to -40 dB: 0 dB being the loudest input signal that

can be accepted 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 setting for experimentation is -10 dB.

voice level goes above the threshold. The range is from 1:1 (no gain reduc-

tion) to Inf:1 (maximum vocal gain reduction ). A typical setting for Ratio is

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 compressor works is this: say a word

you sang went 4 dB over the threshold when the Ratio was set to 4:1. The

compressor would only allow it to go 1 dB louder.

Note that the Ratio control has to be set above 1.0 (1.0:1) to apply any com-

pression regardless of the setting of the Threshold.
