1 Welcome

Congratulations on purchasing one of the renowned Crown® Macro-Tech®power ampli- fiers. They are designed to provide enormous levels of pure, undistorted power in a rugged, low-profile package — making them the choice for pro sound reinforcement. They utilize our patented ODEP® protection circuitry to keep the show going long after other amplifiers have shut down. And with their PIP™ expandability, Macro-Tech amplifiers can be easily custom- ized with one of our many optional input mod- ules (see Section 5 for a list of available PIPs).

Modern power amplifiers are sophisticated pieces of engineering capable of producing extremely high power levels. They must be treated with respect and correctly installed if they are to provide the many years of reliable service for which they were designed.

In addition, the Macro-Tech 02 Series amplifi- ers include a number of features which require some explanation before they can be used to their maximum advantage.

Please take the time to study this manual so that you can obtain the best possible service from your amplifier.

1.1 Features

•Crown’s Grounded-Bridge™ design deliv- ers large voltage swings without using easily stressed output-transistor configu- rations like conventional amplifiers. The results are lower distortion and superior reliability.

•Patented ODEP (Output Device Emulation Protection) circuitry compensates for

overheating and overload to keep the amplifier working when others would fail.

•Complete protection against shorted, open, and mismatched loads, overheating, DC, high-frequency overload, and full internal fault protection provided by our latest protection scheme: “Quad-Mute.”

•Two mono modes (Bridge-Mono and Parallel-Mono) for driving a wide range of load impedances.

•Dedicated power supply transformers iso- late channels in Stereo mode for superb crosstalk characteristics and reliability — each channel is virtually a separate amplifier.

•High damping factor provides superior control over low-frequency drivers for a clean, accurate low end.

•PIP (Programmable Input Processor) con- nector accepts accessories that tailor the amplifier to suit specific applications.

•Enhanced PIP2™ (Programmable Input Processor) connector accepts new acces- sory modules that further tailor the ampli- fier to suit specific applications, including wideband load current monitoring.

•Backed by the industry’s ONLY three-year, no-fault, fully transferable warranty.
