Turn up the heat

Hitachi delivers a 50-percent storage capacity increase in its line of “extreme” hard disk drives. The EndurstarJ4K30 and Endurastar N4K30 are both offered in capacities of up to 30GB, and are designed specifically to perform in extreme temperature environments. With an operating temperature range as wide as -20°C to +85°C, the new Endurastar models are built to perform in the harshest environments—from the desert heat to the Antarctic chill.

Ideal for automotive applications

Endurastar hard drives are the preferred solution for automotive applications or other environ- ments which require high robustness and wider operating temperatures than standard hard drive applications. In fact, the Endurastar J4K30 is already being used in car entertainment and navigation applications—and 30GBs of storage means users can store more than 5,000 audio files, four hours of MPEG2 video and enough navigation data to cover the entire planet!

Reliability and performance

30 and 20GB 4200 RPM ATA-5The new Endurastar models feature glass media and load/unload technology in addition to shock sensor technology which cushions the drive in less than ideal shock or vibration conditions. Endurastar drives incorporate fluid dynamic bearings (FDB) in the spindle motor, allowing the same quiet operations and improved shock characteristics as with PC models, but offers even higher reliability for automotive environments and around-the-clock applications in industrial environments. These features enable the Endurastar drives to achieve a non-operating shock tolerance of 800G/1ms and an operating shock tolerance of 250G/2ms.

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.
