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.)
