MA12000I - Overview

The Crown MA12000I is a 2-channel, 4500W @ 4Ω Power Amplifier and is part of the Macro-Tech i Series, which offers amazing power, is light weight and is easy to use for touring sound applications. The series includes onboard analog signal processing and a built-in network connection.

  • Features:

    • 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 9000W 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 2 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
