Description: Removed from a air-condition church, never driven hard. XLR or 1/4" Phono inputs INTRODUCTION The Micro-Tech Series of Crown amplifiers are designed to provide high power with extremely low distortion for use in audio applications. The key focus of this amplifier series is obtain an optimum combination of power, price, weight, and physical size.

Rail voltage is not grounded at the power supply, but by two quadrants of the output stage. The result is voltage control allowing maximum power transfer to the load, but never placing more than half the output voltage across any output transistor device. These amplifiers also have Output Device Emulation Protection (ODEP) to protect the amplifier from unsafe thermal conditions. Unlike conventional thermal switches, the ODEP circuit steps in to limit drive only as much as necessary to protect the output stage rather than causing an abrupt shutdown. With ODEP, “The Show Goes On!” Front panel indicators are provided to show the thermal headroom of the amplifier. If it begins to run out of thermal headroom the ODEP indicators dim. After they go out the amplifier may begin to limit output drive to protect the amplifier thermally. Other protective circuitry includes slew rate limiting to prevent RF burn-out of high frequency transducers, output current limiting, and audio muting in the event of output DC or output device failure. Another circuit innovation in these amplifiers is the use of the fan motor as the low voltage transformer. Low voltage transformer windings are wound in the form of a motor for the fan.
