Features
• The Macro-Tech® i Series continues the Crown®
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 amplifi er 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 amplifi er from any
location

BASIC Series - Intelligent Power
BASIC - that's meeting the tightest budgets and professional requirements in reliability, flexibility and sound. Alone or in combination with the other products of the Bittner portfolio. The consequent realisation of the Bittner quality standards indicates once more our understanding of the contracting business. It underlines our philosophy that cost consciousness has nothing to do with giving up standards. Compromise is a word unknown to Bittner Audio! The incorporation of detent potentiometers, clip limiter, protection circuits for any imaginable situation, as well as a first-class production process using only highest-quality components made the BASIC series the choice of most contractors.
Certainly more than basic!
