Crown I-Tech 9000HD is a professional two-channel touring power amplifier engineered to deliver reliable performance, precise audio reproduction, and efficient power delivery for demanding sound applications. Built on Crown’s decades of audio engineering innovation, it features five patented technologies, including three related to its power supply.

At the heart of the Crown I-Tech HD is the BSS OMNIDRIVEHD digital signal processing engine, featuring IIR filters, linear-phase FIR filters, and LevelMAX peak voltage and RMS power limiters. Its 24-bit, 192kHz Cirrus Logic SHARC A/D and D/A converters provide high-definition signal processing, while Sweep Load Monitoring (SLM) supports system-level diagnostics.

The Crown I-Tech HD offers versatile connectivity through analog, AES/EBU, CobraNet, HiQnet, and Ethernet interfaces, with flexible input routing to amplifier outputs. Its universal power supply accepts 100–240V AC at 50/60Hz (±15%), while the front-panel USB connector enables convenient DSP preset transfers.
