TL Audio 5021 - Manual (Page 21)

7. When gain reduction is taking place, you should notice that the output
level is reduced. By switching the compressor ‘in’ and ‘out’, you can
compare the levels and the subjective sound quality of the original and
compressed signals. With the compressor active, use the Gain Make-
Up control to set the level so that when disabling the compressor, there
is no level drop. This way you can A/B the original and compressed
signals without the levels changing.
8. At this stage if you are unfamiliar with compression you should
experiment with each control to see how it affects the sound. Until you
are familiar with using compressors it can be difficult to hear these
changes, as a good compressor will retain the natural sound of the
source signal. If in doubt aim to use compression gently as it can be
difficult to compensate for over-compression. On the other hand there
are no rules, so if extreme settings get you the effect you are after, the
choice is yours. Let your ears be the guide.
9. For stereo signals or mixes, channels A and B need to be linked by
activating the ‘Stereo Link’ switch in the centre of the 5021. This
enables both channels to react equally whenever a signal on either
channel exceeds the threshold point. To maintain a consistent stereo
image the controls on both channels need to be set to the same values.
