to replace this ‘lost’ level and in the case of the P1 this is done
automatically; the amount of make-up gain applied being related to
the threshold and ratio settings.
The use of compression when recording both vocals and instruments
is a very powerful way of achieving the desired ‘live’ sound and so is
often used at the track laying stage as it can actually improve the
quality of the performance given by the artist. However it is also
possible to use the P1’s compressor as an effects device during mix
down.
As a general rule when recording; use compression sparingly
unless you are intentionally seeking a dramatic sound effect.
We will now detail some common uses of the P1 compressor. In
each case remember to set the input gain correctly before
switching in the compressor.
Vocal tracks : Most commercially recorded vocal tracks have some
compression applied. This is often done to help the vocal sit properly
in the mix and it also helps to even out the artist’s performance.
Before switching in the P1’s compressor, adjust the settings of the
threshold, attack and ratio controls as shown below.
Now switch in the
compressor. As the
threshold is set to 0dB there
will be no audible
effect.
Now slowly turn up the
threshold control until the
gain reduction meter is
peaking between 4dB and
6dB. This should be enough
for most vocals. Now let’s
turn to the attack and ratio
settings.
If you find that some of the first syllable vocal phrasing is still
uncontrolled or that the vocalist tends to lean into the microphone at
