8.1 P.I.P. Modules

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:

WARNING: Disconnect power to the amplifier when in- stalling or removing a P.I.P. module.

Here are some of the available P.I.P. modules:

Input Processor (P.I.P.)

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 B6 vented box equaliza- tion. Biamping and triamping capabilities are provided via XLR connectors.

Input Processor (P.I.P.)

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

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.

Input Processor (P.I.P.)

P.I.P.-FTE includes all P.I.P.-FXT features, and adds

12dB/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,™SMX-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, ODEP 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.

Input Processor (P.I.P.)

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-
