setting. This should have no audible affect. Now turn up the
threshold control slowly so you lose as much as the background
noise as possible without losing the natural decay of the vocal
phrases. Make sure you turn up the threshold control far enough so
that the background noise doesn’t drift back during very quiet or
silent passages.
Occasionally, there are times when you may want to use the
expander when recording; for example;
You are doing some ‘guide track’ vocal recording through the P1 into
an absolutely state of the art super fast PC which generates fan
noise of a similar level to an F16 fighter jet! And no amount of
microphone placement in your studio makes it much better. Whilst
you could strip out the worst of the background noise after recording
using the P1 you just want a quick guide vocal track and the
background noise in the headphones is getting on your nerves, so;
Connect the P1 in the normal way for recording new source material.
Switch in the P1’s expander and start with the THRESHOLD setting
at the –60dB setting. This should have no audio affect. Now turn up
the threshold control just far enough that most of the background
noise disappears and the vocals still come through clearly.
