J4K30, N4K30 specifications

Hitachi N4K30 and J4K30 are two advanced production-grade projectors that exemplify Hitachi's commitment to delivering high-quality imaging and versatility for various presentation and entertainment applications. With robust features and cutting-edge technologies, these projectors stand out in the competitive marketplace.

The Hitachi N4K30 is designed primarily for large venues and professional installations. It offers a native 4K resolution, delivering stunningly detailed images that capture every nuance of color and clarity. This projector uses DLP technology, ensuring excellent color accuracy and brightness. One of its standout characteristics is its brightness, reaching up to 30,000 lumens, making it suitable for environments with significant ambient light.

The projector is equipped with a range of lens options, allowing for flexible installation and precision image placement. With interchangeable lenses, users can easily adapt the N4K30 for various screen sizes and distances, ensuring optimal viewing experiences. The lens shift functionality further enhances flexibility, enabling adjustment to the image without compromising quality.

On the other hand, the Hitachi J4K30 is a slightly lighter alternative, offering similar 4K resolution and brightness but tailored for slightly smaller venues or applications where portability is essential. This model is particularly beneficial for rental and staging applications, as it maintains high-performance levels while being more accessible in terms of handling and setup.

Both projectors feature Hitachi’s innovative technology, including advanced color processing capabilities that greatly enhance contrast and color fidelity. They utilize HDR (High Dynamic Range) technology, which increases the range of brightness levels, delivering deeper blacks and brighter whites that elevate the overall visual experience.

In terms of connectivity, the N4K30 and J4K30 are equipped with multiple input options, including HDMI, DisplayPort, and many other professional-grade connections. This versatility allows for easy integration with various devices, from laptops to advanced media players.

Additionally, the projectors come with robust management and control capabilities, such as web-based monitoring, enabling users to keep track of performance and quickly address any maintenance needs.

Overall, the Hitachi N4K30 and J4K30 projectors represent a fusion of high-end features, innovative technology, and user-friendly design, meeting the demands of professional environments and providing exceptional visual experiences.
