Crown Macro-Tech Series Amplifers

Crown Macro-Tech® Series amplifiers deliver superior sonic accuracy and enormous amounts of power from a low profile design, and are perfect for touring and fixed installations.

Crown® Macro-Tech 02 Series amps are enhanced versions of the Macro-Tech line. They offer the same features and performance of the original Macro-Techs while delivering key added benefits that continue to expand the versatility of this distinct product line.

When it comes to manufacturing amplifiers, there are no shortcuts to quality. Crown’s Macro-Tech amplifiers have proven themselves time and time again in some of the most demanding applications in the world. Little wonder then that a Crown is the most coveted amplifier in the business.

HiQnet Compatible Logo

Crown's patented Grounded Bridge™ circuitry generates incredible output voltage swings with ultra-low distortion and superior reliability. The patented Output Device Emulation Protection (ODEP) protects the amplifier and keeps the show going even under adverse conditions that cause lesser amplifiers to fail. Front panel indicators show each channel's ODEP status. Several optional PIPTM modules also provide powerful ODEP-driven features. An enhanced PIP2 (Programmable Input Processor) socket accepts new accessory modules that tailor the amplifier to fit specific applications such as HiQnet™ or TCP/IQ™. The Crown Macro-Tech Series amplifiers are rated for load impedances from 2 to 8 ohms per channel and 4 to 8 ohms in bridge mode, providing power outputs between 220W and 1050W per channel depending on model and load
