Crown MA 9000i 2-Channel Power Amplifier (Discontinued)

Description

Details

The Macro-Tech i Series includes onboard analog signal processing and a built-in network connection.

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, MA-i Series amplifiers include a number of features which require some explanation before they can be used to their maximum advantage.

Features

Features

The Crown Macro-Tech i Series continues the Macro-Tech legacy of unparalleled sonic accuracy and detail, putting sound quality above all else
Patented, cutting-edge Class-I circuitry gets more power out of an amplifier with less waste
Rugged construction ensures that all Macro-Techs are built to withstand years of abuse on the road
Global Power Supply — designed to deliver maximum power no matter what country you work in
Built-in load, line voltage, input and output monitoring
Standard Ethernet networking via System Architect® lets system operators monitor and control the amplifier from any location
High power density, up to 7000 watts in a 2U chassis
Highest output voltage in the industry (200V peak) provides clean transient peaks
Precision detented push-to-mute attenuators with multiple LEDs that show attenuator position, mute status or level
Light weight due to aluminum chassis, special internal construction and switching power supply
Thermal management controller and two discrete thermal zones with variable-speed fans, forced-air cooling
Advanced protection circuitry guards against: shorted outputs, DC, mismatched loads, general overheating, under/over voltage, high-frequency overloads and internal faults
