The Crown I-Tech 4x3500HD is a powerful, 4-channel amplifier designed for professional touring and large-scale sound reinforcement applications. Delivering 4000 watts per channel at 4 ohms, this amplifier is equipped with advanced DSP technology and a robust feature set that ensures superior audio performance and system flexibility. Built with Crown's patented DriveCore technology, the I-Tech 4x3500HD offers an unmatched combination of power, precision, and reliability, making it a top choice for demanding live sound environments.

At the heart of the I-Tech 4x3500HD is the BSS OMNIDRIVEHD processing engine, which delivers superior audio clarity and signal purity. This DSP engine operates four times faster than previous versions and features Linear Phase FIR filters and LevelMAX limiters, ensuring precise control over audio output. The amplifier's advanced digital signal processing allows for highly accurate filtering and limiting, which results in unmatched clarity and protection for your sound system. The I-Tech 4x3500HD is ideal for high-demand applications such as concerts, festivals, and large venues where both power and sonic accuracy are critical.

One of the standout features of the I-Tech 4x3500HD is its ability to deliver 4000 watts per channel at 4 ohms, with additional power options for various load configurations, including 3500 watts at 2 ohms and 2100 watts at 8 ohms. In bridged mode, the amplifier can push up to 6000 watts at 4 ohms and 7000 watts at 8 ohms, making it ideal for driving large loudspeaker arrays and subwoofers in high-SPL environments. This amplifier's power density is one of the highest in the industry, all within a compact 2U rack space chassis.

The I-Tech 4x3500HD also features Crown's patented Class I (BCA) circuitry, which ensures efficient power delivery to the load while minimizing AC current draw. This results in lower power consumption and higher overall efficiency, which is essential for touring applications where power availability can be inconsistent. Additionally, the amplifier includes a global power supply with Power Factor Correction (PFC), allowing it to operate seamlessly in any region of the world without needing external transformers or voltage converters.

In terms of connectivity and control, the I-Tech 4x3500HD includes a full suite of network and monitoring features. It is equipped with an EtherCon Ethernet connector for HiQnet control or CobraNet digital audio transport, allowing for remote monitoring and control over standard CAT 5 cabling. The amplifier supports AES/EBU digital audio input, and its analog and digital thru connectors provide flexible signal routing options. This "Single Plug" design streamlines installation and makes it easy to integrate the amplifier into complex audio systems.

The front panel of the I-Tech 4x3500HD features an intuitive LCD control screen, which allows users to adjust attenuation, configure the amplifier, and recall DSP presets directly from the amplifier. The screen also provides real-time feedback on system status, error monitoring, and diagnostics, making it easy to manage the amplifier in live sound settings. Comprehensive status indicators, including Power, Data, Ready, Signal, Clip, Thermal, and Fault for each channel, provide quick diagnostics to ensure smooth operation.

Designed for the rigors of touring, the I-Tech 4x3500HD is built with a rugged aluminum chassis and weighs just 29 lbs, making it one of the lightest amplifiers in its class. Its compact 2U form factor allows for easy transport and installation, whether in permanent installations or mobile rigs. Despite its lightweight design, the amplifier is equipped with a powerful thermal management system, including variable-speed fans and two discrete thermal zones that ensure optimal cooling during prolonged use. This system helps prevent overheating, extending the life of the amplifier and maintaining reliable performance under extreme conditions.

Another key feature of the I-Tech 4x3500HD is its advanced protection circuitry, which guards against a wide range of potential issues, including shorted outputs, DC faults, mismatched loads, overheating, and under/over voltage conditions. This ensures that the amplifier remains safe and operational even in challenging environments, providing peace of mind for sound engineers and technicians.

For sound professionals looking for a versatile, high-powered solution, the Crown I-Tech 4x3500HD offers an unbeatable combination of power, DSP flexibility, and reliability. Its high output power, compact form, and advanced features make it a top choice for large-scale sound reinforcement, touring applications, and installations requiring the highest level of audio performance.
