Auto Rel
Auto Rel modifies how quickly the compressor releases after compression (that is,
how quickly it stops compressing when the signal returns below the threshold). The
release on the Voicebox has been optimised for vocal use, which under certain
circumstances may not sound natural. Auto Rel reacts to the dynamic range of the
input, so the higher the signal is above the threshold, and the longer it stays there,
then the slower the release is. This means that fast signals that aren’t compressed
hard have a fast release time, while longer signals release more slowly, which makes
the compression in context with the signal.
Make-up Gain
Compressing a signal makes it quieter. After you have set the compression on the
signal, use the make-up gain to restore the signal to its original or desired volume.
For example, in the diagram the compressor reduces the signal by 20 dB, which
reduces the dynamic range of the input and in so doing makes the signal quieter.
Using the make-up gain restores the volume of the compressed signal.
If you make heavy use of make-up gain, you can introduce hiss into the signal - if so,
counteract it by using the NR control (as described earlier).
How to Use Compression
1. Using an input signal with wide dynamic range, set the controls in the following
starting positions:
