The release determines the level of the quietest signal. The combination of ratio,
threshold and release determines the overall dynamic range.
• If transients are not being compressed quickly enough, use the Fast switch to
give a faster attack.
4. Adjust the make-up gain to set the level of the output signal.

When to use Gating or Expansion

Use the gate or expander on a signal when there is a certain part of the signal that
you want to cut out, while letting the rest through. For example, when recording a
band live, microphones may pick up spill from other instruments, so you can use the
gate or expander to get rid of the spill.
Whether you use the gate or the expander depends on the type of material you are
recording. For example, you normally use the gate when recording drums, but when
recording vocals you normally use the expander, since you might hear the gate
cutting off the beginning and end of phrases as it opens and closes.

How to use Gating or Expansion

1. Set the release in the middle, and the threshold on minimum.
2. Select the Fast button when gating if it is important that the gate opens quickly
(for example, when recording a snare drum). When using the expander, the Fast
button is less noticeable.
3. Set the threshold so that the signal causes the gate/expander to open
successfully. If the end of the signal is cut off by the gate/expander closing,
lengthen the release time.
4. If necessary adjust the threshold again (particularly if you have made the
release faster).
