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 is 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.
