It combines cutting-edge technology with ease of use, offering industry-leading power density, advanced DSP capabilities, and unmatched system integration features. The amplifier is designed for maximum performance and reliability, making it a top choice for sound engineers who demand the best in power, clarity, and control.

At the heart of the I-Tech 4x3500HD is Crown's proprietary BSS OMNIDRIVEHD processing engine. This advanced DSP engine is four times faster than previous iterations, providing precise signal processing with Linear Phase FIR filters and LevelMAX limiters. The result is unparalleled clarity and sonic purity, allowing for clean and transparent audio reproduction across all channels. Whether used in concert halls, stadiums, or large-scale outdoor events, the I-Tech 4x3500HD delivers consistent and high-quality audio performance.

This amplifier offers a staggering 4000 watts per channel at 4 ohms, 3500 watts at 2 ohms, and 2100 watts at 8 ohms. It also supports bridge mode, delivering 6000 watts at 4 ohms and 7000 watts at 8 ohms. These power ratings make the I-Tech 4x3500HD ideal for driving large, high-power speaker arrays in demanding environments. Crown's patented Class I (BCA) circuitry ensures that power is delivered efficiently to the load while minimizing AC current draw, which reduces energy consumption and operating costs.

One of the standout features of the I-Tech 4x3500HD is its advanced global power supply with Power Factor Correction (PFC). This power supply is capable of operating anywhere in the world, adapting to different voltage environments without sacrificing performance. PFC ensures that the amplifier can draw consistent current, even in venues with inconsistent power delivery, ensuring uninterrupted performance.

Onboard high-definition DSP enhances the amplifier's versatility and ease of use. It features 24-bit, 192 kHz Cirrus Logic SHARC A/D and D/A converters, providing the highest audio resolution and fidelity. The DSP includes advanced IIR and Linear Phase FIR filters, along with programmable presets that simplify setup. Custom presets can be downloaded and stored via the front-panel USB connector, allowing users to tailor the amplifier to specific loudspeaker configurations or venue requirements.

The I-Tech 4x3500HD also features a comprehensive network and control suite, making it easy to integrate into larger audio systems. It includes an EtherCon Ethernet connector for HiQnet control and CobraNet digital audio transport, allowing for remote control and monitoring of the amplifier via standard CAT 5 cabling. This "Single Plug" connection simplifies installation by enabling both control and digital audio to be transmitted through a single cable. Analog and digital thru connectors further enhance its connectivity options, ensuring flexibility in complex sound systems.

The front panel of the I-Tech 4x3500HD is equipped with an intuitive LCD control screen that provides real-time feedback on the amplifier's performance. Users can adjust attenuation and muting, configure the amplifier's settings, monitor error conditions, and recall DSP presets all from the front panel. This makes the amplifier highly adaptable, whether it's being used in a fixed installation or a mobile touring rig.

Thermal management is handled by two discrete thermal zones and variable-speed fans, which work together to ensure that the amplifier operates within safe temperature ranges. The forced-air cooling system keeps internal components cool even during extended periods of high output, protecting the amplifier from overheating and extending its lifespan. The I-Tech 4x3500HD also features advanced protection circuitry to guard against shorted outputs, DC faults, mismatched loads, and under/over voltage conditions.

The amplifier is built for durability and ease of transport, featuring an aluminum chassis that is both lightweight and rugged. Weighing in at only 29 lbs and with a 2U rack space design, the I-Tech 4x3500HD is easy to move and install, making it ideal for touring applications. Its compact form factor belies its immense power, delivering up to 8000 watts in a single 2U chassis, one of the highest power densities available in the industry.

In terms of diagnostics, the I-Tech 4x3500HD offers a comprehensive array of indicators, including Power, Data, Ready, Signal, Clip, Thermal, and Fault for each channel. This allows for quick troubleshooting and ensures that users can monitor the amplifier's performance in real-time. The AC mains indicator built into the power switch provides clear confirmation of the amplifier's power status, ensuring that it is always operating safely and efficiently.

For professional sound engineers and live sound applications that demand the highest level of performance, the Crown I-Tech 4x3500HD is a top-tier choice. Its combination of immense power, advanced DSP capabilities, and robust network control makes it one of the most versatile and reliable amplifiers available for touring and large-scale sound reinforcement.
