I-Tech 12000HD Two-channel, 4500W @ 4Ω Power Amplifier

Crown I-Tech HD Amplifier

The I-Tech HD is one of the most technologically advanced touring amplifiers available, designed for professionals who demand uncompromising performance, flexibility, and reliability. Building on decades of Crown innovation, the I-Tech HD incorporates five new patents—three just for the power supply—delivering capabilities far beyond traditional amplifiers. At the core of this powerhouse is the BSS OMNIDRIVEHD™ DSP engine, which is four times faster than its predecessor and includes Linear Phase FIR filters and LevelMAX™ limiters for sonically pure, precise audio processing.
