The Crown I-Tech 4x3500 HD is a high-density, four-channel professional power amplifier renowned for its exceptional power output, advanced digital signal processing, and touring-grade reliability. Designed for the most demanding large-scale sound reinforcement applications, it delivers a substantial 4000 watts per channel when driving 4-ohm loads, making it capable of powering large line arrays, subwoofer clusters, and high-output stage monitors in concert touring, festivals, and major fixed installations. This amplifier combines immense power with precise control, serving as both an amplification and system optimization hub.

Beyond raw power, the I-Tech HD series integrates comprehensive onboard DSP (Digital Signal Processing) via Crown's proprietary HiQnet System Architect software. This allows system technicians to configure detailed crossover filters, parametric EQ, dynamics processing (limiters, compressors), and time alignment delays directly within the amplifier, eliminating the need for external processors in many cases. Its advanced LoadMatch technology compensates for cable losses, and its Intrinsic Correction helps linearize the response of connected loudspeakers, ensuring accurate, controlled sound.

Housed in a robust 3U rackmount chassis with substantial cooling capacity, the I-Tech 4x3500 HD is engineered for continuous operation under heavy load. It features multiple protection circuits, comprehensive status monitoring, and both analog and digital (AES/EBU) inputs. By merging colossal amplification power with sophisticated, speaker-specific processing in a single unit, this amplifier represents a top-tier solution for audio professionals who require absolute performance, reliability, and granular system control for large, complex sound systems.
