The REALiS WUX400ST D Pro AV Short Throw Compact Installation LCOS Projector brings together in one unit the ability to fill a big screen with brilliant quality images while simultaneously offering flexible installation options.

Throw Ratio
From large conference rooms and auditoriums to houses of worship and museums, users of the WUX400ST D can appreciate its short throw of 0.56:1 that is capable of filling up a large 7 foot screen from as close as only 4 feet away. And this capability comes along with beautifully rendered images and video, without sacrificing clarity, brightness or color reproduction.

Mechanical Lens Shift
The WUX400ST D is an extremely flexible projector that works well under a diverse range of installation scenarios to meet your organization's specific requirements. Its built-in, mechanical lens shift is capable of a wide range. Vertically, the projector's shift range can be set from 0 to 75%. Horizontally, it can be adjusted from between +/- 10%.

Fixed Top Zoom Function
In the past, it has been sometimes difficult to fully utilize the zoom feature in an installation projector, as you would have to tilt the projector. Doing so could result in a distorted, trapezoidal picture or video that would then require keystone correction — sometimes at the cost of image quality.

The WUX400ST D helps to make this challenge a thing of the past! With its fixed top zoom function, users can easily zoom in or out while maintaining the height of the projection position. Lowering the position of the projected image or video can be as simple as adjusting the unit's mechanical lens shift function.

The REALiS WUX400ST D Pro AV Short Throw Compact Installation LCOS Projector allows your audiences to view presentations and videos as you intended — with striking clarity and brightness, and stunningly beautiful crisp colors across the spectrum in striking high-definition.

Native WUXGA Resolution (1920 x 1200)
Let your presentations, video demonstrations and pictures come alive with the WUX400ST D. Its native WUXGA widescreen high resolution (1920 x 1200) in the 16:10 aspect ratio delivers incredibly clear imagery that your audiences can appreciate as they become engaged in your message and enjoy their viewing experience.

4000 Lumens
The WUX400ST D produces a bright 4000 lumens and boasts a 2000:1 contrast ratio that allows you to project life-like, beautiful and virtually distortion-free images, presentations and video to your audience. Despite its high lumen count, presenters will not need to be concerned about glare, as the projector's light does not enter the field of vision, allowing the user to focus on the presentation — not on glare.

Canon's proprietary AISYS 5.0 optical engine, in combination with the WUX400ST D's 4000 lumens, enhances contrast and brightness through improved light management compared to our previous AISYS optical engine, and is capable of projecting onto screens up to 110" without sacrificing the high image and HD video quality that your audience deserves. Additional value can be found with its wide range lens shift (Vertical: 0% to 75%; Horizontal: +/- 10%) and its image reformation projective optical system. Canon's optical technology helps minimize the ghosting and chromatic irregularities.

Genuine Canon Lens
The same optical technology developed for our acclaimed EOS series of SLR cameras is reflected in the development of our projection lenses. The 1.35x Electronic Zoom Lens fitted to the WUX400ST D, in combination with its superb image processing, helps this projector to deliver image quality to your screen that is truly remarkable.

Image Processing
If a picture is worth 1,000 words, it's smart to make each one vibrant and memorable! The WUX400ST D can make this challenge simple. In order to check for proper installation alignment and aspect ratio setting, the unit includes built-in test patterns that enable PC-less calibration without a test pattern generator.

When two projectors are necessary in order to effectively communicate your entire presentation, the WUX400ST D's built-in edge blending processor seamlessly combines the two projected images. The unit is capable of overlapping 0-960 horizontal pixels and 0-600 vertical pixels. Canon's easy to use, built-in processor corrects for over brightness within the intersected areas for seamless projection. Its low TV distortion (0.1%) supplies crisp, beautiful and uniform horizontal and vertical blending.

Finally, high image quality is achieved through the use of LCOS technology, to help ensure the most advanced grayscale capable of producing extremely sharp, distinct and smooth highlights and shadows.

The DICOM Simulation Mode of the REALiS WUX400ST D Pro AV Short Throw Compact Installation LCOS Projector is included specifically for scientific organizations, medical schools and lecture demonstrations of medical materials. When the projector is placed in this mode, it is capable of non-diagnostic, large screen projection of X-ray and CT images onto large screens, while being in compliance with the DICOM grayscale standard display function. Presenters have the ability to alter the color temperature between 5 presets (3 user defined color temperatures, a clear base and a blue base).

The REALiS WUX400ST D Pro AV Short Throw Compact Installation LCOS Projector is the smallest projector in its class. It measures 13.3" x 4.6" x 16.4" (WxHxD) and weighs a mere 13.4 lbs., contributing to its remarkable flexibility in installation. The unit can also be installed vertically, in order to provide even greater installation flexibility in the tightest of spaces — allowing you to maximize your installation options without compromising image quality.

The WUX400ST D can be a replacement solution for telephoto and ultra telephoto installations, installed at a short distance from the screen, filling the screen with an image of the same size and brightness as the telephoto lens model it replaces, with less lumens required, for greater efficiency.

The REALiS WUX400ST D Pro AV Short Throw Compact Installation LCOS Projector provides for very rich flexibility and state of the art options when choosing how and where to install the unit. This flexibility and ease of use is further enhanced by its compact design and light weight making the Canon WUX400ST D a simple and easy install projector.

Front or Rear Projection
Owing to its short throw ratio (0.56:1), the WUX400ST D makes for an ideal unit for both front and rear projection.

Utilized as a front installed projector, its built-in lens shift function can enable virtually distortion-free images and videos without the distraction of a bright glare, as its light does not enter into the presenter's line of vision, making this an ideal short-throw projector for lecture halls and large meeting rooms. Because of this, on-screen shadows are virtually eliminated!

As a rear installed projector, the WUX400ST D's short throw ratio becomes a great solution for space-restricted areas, such as surveillance rooms, events and simulations.

Telephoto / Ultra Telephoto Applications
The WUX400ST D is an excellent replacement choice for units normally used in telephoto and ultra telephoto applications. This type of installation, at the rear of a room, on a high tower or ceiling mounted, can be costly and require significant work and time to install. Long cable runs can also reduce image quality. Say goodbye to these challenges. The WUX400ST D can be a cost-effective alternative, taking less time and effort to install. Making use of less expensive, shorter cables can save money, without sacrificing high quality resolution, clarity or ease of use.

For greater flexibility, double the brightness and even larger projected images and videos, two WUX400ST D projectors can be stacked. Even with two units, its compact and lightweight design makes it possible for the pair to fit into areas where many other projectors could not be as easily accommodated.

Ceiling Mounting
The light weight and compact size of the WUX400ST D help make a ceiling installation an easier task. Optional feet can be fitted on the unit for an inverted mount.

The WUX400ST D can also be installed vertically for greater flexibility and convenience.

Easy Maintenance
In Canon's comparative testing, the WUX400ST D consumed less than .081W per lumen. This low ratio helps to extend the life of its lamp to 3,000 hours (or 4,000 hours in Eco Mode). Furthermore, its filter design provides for up to a lengthy 12,000 hours of operation before needing replacement.

Both the lamp and the unit's air filter can be easily replaced while the projector is installed — even if ceiling mounted, in order to greatly enhance ease of use, ease of maintenance and simplicity.

Flexible use, cost-efficiencies and high performance merge into one, behind the networking power and simplicity of the REALiS WUX400ST D Pro AV Short Throw Compact Installation LCOS Projector.

Control Over IP
Included in the WUX400ST D is a full suite of network features including full control over IP. Power management, usage tracking and control can be done over the onboard LAN port for up to 250 projectors on the network. Operate, track, monitor and generate operating reports for your organization with ease. Integrated Creston Room View support is also provided.

Projector Management
The WUX400ST D's onboard LAN port allows for power management, usage tracking and control for up to 250 projectors on a network — a boon for schools or in trade show applications.

Another key network feature is the content streaming capability. Without dedicated software, one or more PCs can connect to the WUX400ST D over a standard LAN to share content.

Simultaneous Multi-Screen Projection (Picture by Picture)
The WUX400ST D has a built-in processor to show up to 4 different screens simultaneously, using both HDMI and DVI digital video inputs. This can be done within a room, or in multiple locations, helping to simplify installation.

Projecting without a PC is possible with the WUX400ST D Pro AV Short Throw Compact Installation LCOS Projector. The projector includes a USB memory stick slot and pre-installed support for MS Office files, Adobe PDFs, and select image, video and audio files. You will enjoy flexibility and convenience to showcase your work under a wide range of presentation scenarios and requirements.

USB Port for Memory Sticks
A USB port located in the back of the unit allows you the flexibility and convenience to make presentations without a PC. The USB port can also be utilized to update the unit's firmware, so that you may never need to uninstall your projector — which could save you valuable time.

JPEG Image Support
Business professionals, university educators and others that rely on JPEG images to communicate a richer and more fully realized presentation will appreciate the WUX400ST D's support of this format through the use of the USB port. The projector's new image processor races to deliver most images in less than 2 seconds, without the need for a PC computer.

Built-In Speaker
In presentation spaces and situations where an external sound system is not available, the Canon WUX400ST D features an integrated 5W monaural speaker that delivers crisp, beautiful sound even at a high volume. Whether you need to showcase an audio file or to play a movie for your listening audience, you will not need either a PC computer or peripheral components to do so.

Your audience wants to hear you — not the projector. The REALiS WUX400ST D Pro AV Short Throw Compact Installation LCOS Projector operates at only 38dB, so this is not a problem. Switch the unit to Power Saver mode and the noise level drops to only 32dB.
