T he Crown Macro-Tech Series is the defining standard for amplifier design today. No compromises, no gimmicks. Just brilliant engineering backed by superior manufacturing, support and an unsurpassed commitment to quality. Like all Crown amps, the defining characteristic of the Macro-Tech Series is sonic accuracy. A tight, rock-solid low end, with smooth, detailed highs and a well-defined midrange. In short, the most accurate reproduction of an audio signal you’ve ever heard. And because we put the quality of sound above all else, a Crown is the most coveted amplifier in the business.
When it comes to manufacturing amps, our work is based on one simple fact: there are no shortcuts to quality. And our Macro-Techs have proven it time and time again in some of the most demanding applications in the world.
Developing innovative products that meet your specific needs is what we’re about. MacroTech 24x6 and 36x12 provide a practical solution to biamplified system applications such as stage monitors. Each amp combines a highand medium-power module in a single, lowprofile unit.
Crown’s Grounded Bridge™ design delivers large voltage swings without using easily stressed output-transistor configurations like conventional amplifi ers. The results are lower distortion and superior reliability.
Patented ODEP® (Output Device Emulation Protection) circuitry compensates for overheating and overload to keep the amplifi er working when others would fail.
IOC® (Input/Output Comparator) circuitry immediately alerts of any distortion exceeding 0.05%, providing dynamic proof of distortion-free performance.
PIP™ (Programmable Input Processor) connector accepts accessory modules that tailor the amplifi er to suit specifi c applications.
Convenient high- and medium-power channel design for biamplifi ed systems such as stage monitors.
Very low harmonic and intermodulation distortion results in the best dynamic transfer function in the industry.
Balanced 1/4-inch(6.35-mm) phone jack inputs for each channel, with balanced XLR connectors on the standard PIP-FX module.
Full protection from shorted, open and mismatched loads; general overheating; DC; high-frequency overloads; and internal fault conditions.
