  Professional Studio Amplifiers

One advantage of 

Studio Reference amplifiers is the

ability to customize them using 

P.I.P. (Programmable In-

put Processor) modules. Each amplifier is equipped with
an edge card connector inside the back panel 

P.I.P.

compartment. The modules install easily:

compressors activate when a signal will 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 includes all P.I.P.-FXT features, and adds
12 dB/octave RFI filters, variable 18 dB/octave high-pass
filters, and 6 dB/octave 3 kHz shelving networks for “con-
stant-directivity” horn equalization. Screw terminal plugs
are provided for input.

IQ-P.I.P.-AP  integrates the amplifier into Crown’s pat-
ented 

IQ System.

®

 The IQ System provides centralized

computer control of 1 to 2,000 amplifiers. Each ampli-
fier channel can be monitored and controlled from an
inexpensive personal computer. Any combination of mic-
and line-level signals can also be mixed and routed with
optional 

MPX-6,

 and 

AMB-5

 mixer/multiplex-

ers, and the MRX series matrixers.

IQ-P.I.P.-AP 

Smart Amp

 offers the monitoring and

control features of the IQ-P.I.P.-AP

 plus the ability to

function as a stand-alone unit as part of the 

IQ

System’s distributed intelligence.

 Features include a

smooth output limiter for transparent loudspeaker pro-
tection, power supply gates for energy savings,

conservation which protects the output devices with
precision input signal control, interrupt-driven report-
ing that lets you define error conditions, and config-
urable short detection.

P.I.P.-CLP is designed to detect and prevent overload.
Its compressor is driven by the amplifier’s built-in 

IOC

error detection circuitry. Unlike typical signal-driven com-

stalling or removing a 

P.I.P. module.

Here are some of the available 

P.I.P. 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 com-

pressor. In addition, it provides “constant-directivity” horn
equalization and filter-assisted B

 vented box equaliza-

tion. Biamping and triamping capabilities are provided
via XLR connectors.

P.I.P.-EDCb combines a sophisticated error-driven com-
pressor and smooth limiter with a subsonic filter for each
channel. The compressors have adjustable attack and
release times, and can be set to track each other. The
