Congratulations on your purchase of
Crown’s
P.I.P.
®
–AMCb
.
PIP
TM
modules
are designed to quickly install in the
back of many Crown amplifiers. PIP
stands for “Programmable Input Pro-
cessor.” Each PIP
has features that ex-
pand the capabilities of your amplifier,
enabling you to customize it for your
particular needs.
The P.I.P.–AMCb is a versatile mono-
phonic
Acoustic Modeling Crossover
(version b) that plugs into any PIP-
capable Crown amplifier. It combines
the functions of a crossover, equal-
izer and compressor.
DIP switches, plug-in SIP resistors
and convenient jumper blocks make
it easy to configure any of its power-
ful operating features.
Features
❏ Variable 24-dB/octave (4th order)
Linkwitz-Riley crossover with state-
variable topology.
❏ Variable 12-dB/octave (2nd order)
low-frequency filter with Q=2 for
vented box equalization.
❏ Variable 6-dB/octave high fre-
quency shelving network with vari-
able 12-dB/octave high-frequency
low-pass filter for constant-directiv-
ity horn equalization.
❏ Variable threshold, feedback/error-
driven compressor/limiter with infi-
nite compression ratio.
❏ Configurable compressor control
path.
❏ Fully configurable outputs to supply
the amplifier channels.
❏ Configurable “daisy chain” output.
❏ 3-pin balanced XLR connectors for
input and daisy chain output.
