We will now detail some common uses of the P1 expander. In each
case remember to set the input gain correctly before switching
in the expander.
As a effects unit noise reducer : You have a really favourite classic
guitar effects peddle but it has a very high background noise level.
So record your killer guitar track as normal, then playback the
recorded track through the P1.
Switch in the P1’s expander and start with the THRESHOLD setting
at the -60dB setting. This should have no audible affect. Now turn
up the threshold control just far enough that most of the background
noise disappears and the killer guitar solo still comes through loud
and clear. Check the threshold setting on a few guitar phrases with
slowly decaying notes and maybe make a final small adjustment to
ensure the decaying notes sound as ‘natural’ as possible.
To improve the isolation of one drum sound; It’s quite common
when multi-track recording a full drum kit that getting enough sound
isolation between the individual tracks can be difficult. For example
it’s quite common to get ‘spill’ from the high-hat onto a snare drum
track.
Switch in the P1’s expander and start with the THRESHOLD setting
at the minimum –60dB setting. This should have no audible effect.
Now increase the threshold slowly until the extra high hat beats
between the snare drum beats are removed. If you push too far then
the dynamics of the snare sound will become altered. Sometimes
this is actually used as a way to get a synthetic ‘tight’ sound from an
acoustic drum kit. Keep turning up the threshold control and you’ll
hear what we mean.
To remove background noise on vocal tracks; this may be due to
fan noise from your PC or general room background noise,
sometimes made worse if you have used high levels of compressor
gain reduction to really tighten up a vocal track. Switch in the P1’s
expander and start with the THRESHOLD setting at the –60dB
