The Crown Audio I-T9000HD is a top-tier professional power amplifier engineered for unmatched power, reliability, and audio clarity. Housed in a sleek, durable rackmount chassis, the I-T9000HD combines patented Class-I amplifier technology with OmniDrive HD DSP processing to deliver world-class sound and efficient performance in demanding live and installation environments.
Its advanced Class-I circuitry ensures high output power with minimal current draw, maximizing efficiency without sacrificing sonic integrity. The integrated OmniDrive HD DSP engine features 24-bit/192kHz Cirrus Logic converters and both FIR and IIR filters, allowing for precision tuning and superior sound reproduction.
For flexible system integration, the amplifier includes analog and digital XLR inputs/outputs, Speakon, and Binding Post connectors. A front-panel USB port simplifies DSP configuration transfer, while the Ethernet port enables remote control and monitoring via TCP/IQ, HiQnet, and CobraNet over standard 100Mb networks.
The variable-speed cooling system with front-to-back airflow ensures reliable performance under any condition. Additional features such as Sweep Load Monitoring, system-level diagnostics, and a bright LCD interface make the I-T9000HD easy to use and maintain. With its universal power supply, it delivers full performance anywhere in the world — ideal for touring, live sound, and high-end fixed installations.
