3 Optional Modifi ca-
tions
Some amplifi ers are perceived to
be louder than others while they
actually deliver equal or less pow-
er. Such an amplifi er is typically
set up to clip the input signal, or it
uses built-in compressors that re-
duce dynamic range and increase
average signal levels. This is fi ne if
it's what you want. But if you don't
want it and you can't get rid of it,
it's a problem. This is why Crown
amplifi ers are designed to deliver
maximum power without distortion
or hidden compressors to make
them sound louder.
But what if you prefer the sound
and apparent loudness of a com-
pressed audio signal? In this

case, the P.I.P.-CLP can be modi-
fi ed to simulate the same effect.
Normally, the P.I.P.-CLP protects
loudspeakers from damage that
can result from a clipped signal.
For maximum protection, the
PIP's default configuration pro-
vides super-fast attack and decay
times with an infi nite compression
ratio.
Modifi cations to the PIP can slow
the attack and decay times to al-
low some clipping, which many
listeners perceive as a louder
sound. (This short-term clipping
does not damage loudspeakers.)
