Crown I-Tech 9000HD - 3500W 2-Channel at 4-Ohm Power Amplifier

The Crown I-Tech 9000HD is a powerful and versatile 2-channel amplifier that delivers 3500 watts per channel at 4 ohms, making it ideal for professional touring and high-demand sound reinforcement applications. As part of Crown's renowned I-Tech HD series, this amplifier is built to meet the needs of large-scale sound systems, offering cutting-edge technology, superior sound quality, and unmatched power density. Its combination of advanced DSP, flexible connectivity options, and robust design ensures it excels in even the most demanding live sound environments.

At the core of the I-Tech 9000HD is the BSS OMNIDRIVEHD processing engine, which provides advanced signal processing capabilities. This engine is four times faster than its predecessor and features Linear Phase FIR filters and LevelMAX limiters. These features ensure precise control over audio signals and protect both the amplifier and connected loudspeakers from overload or damage, delivering unparalleled clarity and reliability. The I-Tech 9000HD also integrates high-definition DSP, utilizing 24-bit, 192 kHz Cirrus Logic SHARC A/D and D/A converters to maintain the integrity of the audio signal with pristine accuracy.

The amplifier offers remarkable power output, with 3500W per channel at 4 ohms, 2800W at 2 ohms, and 1500W at 8 ohms. In bridged mode, the I-Tech 9000HD delivers an impressive 5600W at 4 ohms and 7000W at 8 ohms, making it highly versatile for driving a wide range of speaker configurations. Whether powering full-range speakers, subwoofers, or line arrays, the I-Tech 9000HD is capable of delivering the raw power needed for large-scale events and concerts.

The amplifier's global Power Supply with Power Factor Correction (PFC) ensures reliable operation in any location worldwide, regardless of the local power grid conditions. This feature allows touring professionals to use the I-Tech 9000HD anywhere in the world without worrying about voltage compatibility or fluctuations. Additionally, Crown's patented 3rd-generation Class I (BCA) circuitry ensures that power is delivered efficiently to the load while minimizing AC current draw, enhancing the amplifier's energy efficiency.

To simplify setup and integration, the Crown I-Tech 9000HD includes AES/EBU digital audio input, as well as an EtherCon Ethernet connector for HiQnet control and CobraNet digital audio transport. This "Single Plug" connection enables both control and audio transport through a single CAT 5 cable, reducing cable clutter and streamlining system configurations. Analog and digital thru connectors are also included, providing flexible routing options for various audio sources.

The front panel features an intuitive LCD control screen that allows users to adjust the amplifier's settings, such as attenuation, muting, error monitoring, and DSP preset recall. This display makes it easy to configure the amplifier for different loudspeaker systems and optimize performance for specific venues or events. Additionally, a front-panel USB connector allows users to transfer DSP presets to and from the amplifier via a USB drive, simplifying the process of recalling and applying custom settings during setup.

In terms of durability and design, the I-Tech 9000HD is housed in a lightweight aluminum chassis, weighing only 28 lbs, making it easy to transport and install in touring racks. Despite its lightweight design, the amplifier is built to withstand the rigors of professional use, with thermal management features such as two discrete thermal zones, variable-speed fans, and forced-air cooling that prevent overheating during extended periods of operation. These features ensure the amplifier operates reliably under the most demanding conditions, whether on tour or in permanent installations.

The Crown I-Tech 9000HD is equipped with advanced protection circuitry that guards against various faults, including shorted outputs, DC, mismatched loads, overheating, and voltage irregularities. These safeguards help protect the amplifier and connected loudspeakers from potential damage, ensuring long-term reliability and peace of mind for sound engineers and touring professionals.

The I-Tech 9000HD offers a combination of immense power, advanced DSP, flexible connectivity, and robust protection features, making it an exceptional choice for professional sound engineers and touring companies. Its ability to handle large-scale sound systems with precision and efficiency makes it a vital tool in the world of live sound reinforcement, delivering the performance needed to meet the highest standards of modern audio production.
