1 Welcome
Thank you for purchasing the
Crown
P.I.P.-EDCb. P.I.P. ®
modules are designed to
quickly install in the back of
many Crown amplifiers.
P.I.P.
stands for “Programmable In-
put Processor.” Their versatile
features expand the capabili-
ties of your amplifier and en-
able you to customize it for your
particular needs.
The P.I.P.-EDCb adds state-of-
the-art error-driven compres-
sion, signal-driven input com-
pression with adjustable thresh-
old and a configurable sub-
sonic (high-pass) filter to each
input of your amplifier. Three
conditions can cause a com-
pressor to activate: (1) if the
compressor receives an “er-
ror” signal from the amplifier’s
input/output comparator (
IOC ® )
circuitry, (2) if the input signal
exceeds its adjustable thresh-
old, or (3) if an excessively large
input signal level is sensed.
The compressor circuits acti-
vate ahead of all preamp cir-
cuitry resulting in low distor-
tion.
Each channel’s compressor
can operate independently or
both channels can be tied to-
gether causing the compres-
sors to track each other.
Balanced XLR connectors are
provided for quick connection.
