and the usual consequence that the whole vocal phrase then suffers
from over compression. It is often difficult to achieve the attack
speed without the undesirable over compression.
The peakride compressor achieves this by altering the ratio of the
compressor dynamically. So you can set an average compression
ratio on the front panel control but the actual delivered ratio will alter
to suit the dynamics of the audio as it rises above the threshold level.
These principles are at the heart of the peakridedesign and are
achieved by mixing the three compressor side-chains at different
levels and with different compression ratios. In effect, the
compressor side-chain is able to ride the peaks of the audio, reacting
quickly but smoothly to fast attack peaks, and then able to track the
dynamics of the continuing audio till it falls below the threshold point.
Limiter
The P501 includes a switchable audio limiter which can be used to
prevent digital clipping in your recording chain. The limiter is sited in
the audio signal path immediately before the output level control and
operates at fixed threshold of +6dBu (nominal).
The limiter features dynamic adjustment of attack time, so the faster
the audio front edge, the faster the limiter reacts. So fast clipping
protection when tracking but also very useful as a creative tool in its
own right when pushed into heavy levels of limiting.
We’ve added a programme tracking release circuit which provides for
very smooth recovery from limiting, adapting to the natural dynamics
of the audio source.
Bring the limiter into circuit by selecting switch (6) downwards.
