The Crown® Macro-Tech® i Series offers amazing power, light weight and ease of use for touring sound applications. The 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 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 explana tion before they can be used to their maximum advantage.

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
