8.1 PIP and PIP2
Modules
One advantage of Crown PIP2 compatible amplifiers is
the ability to customize them using PIP (Programmable
Input Processor) and PIP2 modules. The PIPs shown
here may be used in any Crown PIP2-compatible am-
plifier. PIPs carrying the PIP2 logo have been config-
ured with an extended, PIP2-enhanced feature set.
The modules install easily:
For PIP units featuring an
edge-connector, first in-
stall the PIP2 adapter,
then carefully slide the PIP
card edge into the
adapter’s edge connector.
Finally, insert the com-
bined units into the ampli-
fier and screw securely
into place (see Figures 8.1
and 8.2).
For PIP2s featuring
ribbon
cable connectors, simply
locate the two connectors
on the underside of the
PIP circuit board, then
connect the two input rib-
bon cables coming from
the amplifier. Both ribbon cables should run smoothly
from the amplifier to the PIP card. Insert the PIP and
attached cables into the PIP opening in the back of the
amplfier, then screw securely into place (see Figure 8.3).
WARNING: Disconnect power to the amplifier when
installing or removing a
PIP module.
For more information on these or other PIPs under de-
velopment, contact your local dealer or Crown’s Techni-
cal Support Group.
IQ-P.I.P.-DSP
is an IQ System Programmable Input
Processor with DSP (Digital Signal Processing) for PIP-
compatible amplifiers. As a component of the IQ System, it
connects the amplifier to the Crown Bus so the amplifier
can be controlled and monitored. Its DSP capabilities
enable it to be programmed with a variety of functions,
such as filters and crossovers, signal delay, input
compressor and output limiter, and a variety of other useful
features similar to those included with the IQ-P.I.P-SMT.
Requires an IQ2 interface and a computer for initial setup.
IQ-P.I.P.-MEM
Integrates Crown PIP-compatible amplifiers
into Crown’s IQ System. Each channel of each amplifier
can be monitored and individually controlled from an inex-
pensive PC. A total of 15 functions can be either monitored
or controlled. Memory backup is also incorporated in case
of power failure. Requires an IQ2 interface and a computer
for initial setup.
IQ-P.I.P.-SMT
“Smart Amp” offers impressive new features
unavailable elsewhere. The processing speed is substan-
tially enhanced over other designs. A programmable power-
supply gate conserves energy by shutting off the amplifier’s
high-power supplies until an audio signal is present. The
user may define error-reporting conditions of the amplifier.
There is much greater flexibility and thermal operational pro-
tection available, as well as a built-in smooth output limiter
to discretely control maximum amplifier output. Requires
an IQ2 interface and a computer for initial setup.
