Thank you for purchasing the
Crown
P.I.P.
®
-CLP
accessor y.
PIP
™
modules are designed to
install easily into the back panel
of many Crown amplifiers. PIP
stands for “Programmable Input
Processor.” Their versatile fea-
tures expand the capabilities of
your amplifi er and enable you to
customize it for your particular
needs.
The P.I.P.-CLP is designed to
detect and reduce overload in
the output stages of Crown
Com-
Tech,

amplifi ers. As the am-
plifi er output reaches the clipping
threshold, an internal error signal
activates the P.I.P.-CLP which
reduces the input gain of the am-
plifi er at a fast yet audibly unde-
tectable rate. This feature provides
an additional 13 dB of input signal
headroom, making it virtually im-
possible to overload the amplifi er.
By following the simple installa-
tion instructions in this manual,
you will expand your amplifi er to
include these capabilities.
Specifi cations
Connectors:
Two female XLR in-
puts; pin 1 is ground, pin 2 is posi-
tive (+) and pin 3 is negative (–).
Signal-to-Noise:
–85 dB (refer-
enced to 0.775 volts) equivalent
input noise from 20 Hz to 20 kHz.
Frequency Response:
Flat
±0.2 dB from 20 Hz to 20 kHz.
Input Impedance (Nominal):
20 k ohms balanced and 10 k
ohms unbalanced.
Limiter Action:
Range of lim-
iter action is restricted to 13 dB
(nominal). Threshold is set to
the point of amplifier overload.
Compression attack time is 0.35
milliseconds; decay time is 160
milliseconds.
