8.1 PIP Modules

One advantage of Macro-Tech amplifiers is the ability
to customize them using PIP (Programmable Input Pro-
cessor) and PIP2 modules. Macro-Tech amplifiers are
equipped with an edge card connector inside the back
panel PIP compartment. The modules install easily:

WARNING: Disconnect power to the amplifier when
installing or removing a PIP module.
PIPs carrying the PIP2 logo are configured to use one
or more of the PIP2 enhanced features. These features
are only available in a PIP2-compatible amplifier. Of
course, the exact features used will depend upon the
function of the PIP2 module. Here are some of the avail-
able PIP and PIP2 modules:
®
P.I.P. –AMCb unites many features of the P.I.P.-XOV and P.I.P.–
CLP. It offers a variable 4th-order Linkwitz-Riley crossover and an
IOC-driven, variable threshold compressor. In addition, it pro-
vides "constant-directivity" horn equalization and filter-assisted
B vented box equalization. Biamping and triamping capabilities
6
are provided via three-pin XLR connectors.
P.I.P. ® –EDCb combines a sophisticated error-driven compres-
sor and smooth limiter with a maximum level setting and a sub-
sonic filter for each channel. The compressors have adjustable
attack and release times, and can be set to track each other. The
compressors activate when a signal would otherwise clip the
input, an IOC error occurs, or the output exceeds the selected
threshold. The subsonic filters have corner frequencies of 24,
28, 32 and 36 Hz.

P.I.P. ® –FTE uses balanced 1:1 transformers to isolate the ampli-
fier from the input signal. It also includes 12-dB/octave RFI filters,
18-dB/octave high-pass filters, and 6-dB/octave 3-kHz shelving
networks for "constant-directivity" horn equalization. Screw ter-
minal plugs are provided for input.

IQ–P.I.P. –MEM is PIP2-compatible and integrates the amplifier
into Crown's patented IQ System. The IQ System provides com-
puter control of 1 to 2000 amplifiers. For example, each amplifier
channel can be monitored and controlled from a personal com-
puter attached to an IQ System. A memory backup feature en-
ables the IQ–PIP–MEM to remember all configuration settings
when the power is turned off.
IQ–P.I.P. ® –SMT is also PIP2-compatible and includes all the fea-
®
tures of the IQ–P.I.P. –MEM plus SmartAmp
the unit has been configured by an IQ System, its SmartAmp
capabilities enable it to function autonomously. We call this dis-
tributed intelligence. The SmartAmp™ features include a smooth
output limiter for transparent loudspeaker protection, power sup-
ply gates for energy savings, ODEP conservation to protect out-
put devices with precision input signal control, interrupt-driven
reporting that lets you define error conditions, and configurable
short circuit detection.
IQ–P.I.P. ® –DSP is PIP2-compatible and provides digital signal
processing capabilities to your amplifier, replacing the need for
outboard signal processing equipment such as equalizers,
crossover networks, signal delays and compressors. In addition,
the IQ–P.I.P.–DSP includes all the SmartAmp features of the IQ–
P.I.P.–SMT to give you access to standard IQ System amplifier
functions and autonomous operation.
