Optoma - EH503 - Large Venue Installation Projector

Optoma - EH503 - Large Venue Installation Projector

The EH503 is a product designed exclusively for demanding professional applications.

1080p and 5200 lumens deliver bright crystal clear images with ultimate reliability, while 24/7 operation ensures that this is a projector on which you can rely.

The dust-sealed, filter-free design prevents dust and dirt from affecting the system ensuring optimal image quality with minimal maintenance.

Full lens shift combined with the multiple lens options provide installation flexibility for simple, trouble-free installations.

Superb image quality is at the heart of every ProScene product design. At every step, commencing with the incredibly reliable, high resolution 1080p DLP® chip where the image is initially created, via the UHP lamp pulsing technology that fine-tunes the color to exacting standards, through to the precision optics to focus the image on a screen, accuracy, and integrity of the image are paramount.

ProScene chose DLP® technology for its image quality and unmatched reliability. The reflective nature of DLP® micro-mirror technology provides highly efficient bright images with great contrast whilst maintaining precise color accuracy and natural, real-world color reproduction. For demanding professional applications, the proven reliability of DLP® technology makes it the obvious choice.

DLP® Technology
DLP® technology from Texas Instruments® is widely recognized and acclaimed for its unmatched reliability and long lasting image performance. When combined with high brightness and native contrast ratios, it becomes the obvious choice for demanding applications. Independent testing has proven DLP® to be the most reliable of projector technologies. Whilst other technologies may show image quality decline after only a few thousand hours, DLP® technology can remain unchanged over hundreds of thousands of hours.

UHP lamps
The 370W UHP lamp provides the highest possible luminance, the essential prerequisite of all highly efficient projectors.

These lamps have outstanding brightness, stay brighter for longer, and provide an optimal color spectrum. In addition, the lamp drivers are specifically tuned for the lamps, ensuring not only optimum operating conditions for every situation but also provide sophisticated lamp pulsing modes and the assurance that color can be fine-tuned according to the application.

Clear, focused images
DarkChip3™ technology from Texas Instruments produces a stunning 2000:1 contrast ratio for pin sharp graphics and crystal clear text. Crisper whites and ultra-rich blacks make images come alive and text easier to read.

Stunning Image Quality
Full HD 1080p technology delivers impeccable image quality associated with the best digital cinema performance around the world. Digital HDMI or DVI signals create a true digital projection system that produces a spectacular High Definition display. This unprecedented combination ensures natural, life-like images with crystal clarity.

Amazing colors
The EH503 incorporates BrilliantColor™ technology to produce stunningly bright images with perfectly balanced life-like colors.

Installation Flexibility
To help meet the seemingly limitless challenges of ProAV installations, the EH503 provides multiple lens options with zoom and focus adjustment to ensure you can get the image size you require, while a wide lens shift range helps you get the image exactly where you want it.

DICOM simulation mode
Designed specifically for larger meeting rooms and lecture theatres, the EH503 includes a special DICOMsim mode that has been specifically tuned for viewing grayscale images, perfect for viewing X-rays and scans during medical training.*

Edge Blending Tools
No two projectors are completely identical. When performing complex, or even simple edge-blend projects using multiple projectors, it can be difficult to achieve good results if the images do not match. The EH503 incorporates the following features to ensure high quality and consistent results.

Color matching
The EH503 has a full 3-axis color matching system, which combined with accurate measurements can create seamless blends every time.

3D technology
Using the inherent speed of DLP® technology, Optoma Full 3D projectors can output video and images at an astonishing rate of 120Hz, allowing you to show full screen, full color, stereoscopic 3D. The 3D effect is generated by splitting this signal into two standard video streams, one for each eye. Using DLP® Link™ technology, the 3D glasses synchronize with the image on the screen to filter each stream to the correct eye. Your brain then combines the two streams to make them jump into life.

The EH503 supports multiple 3D formats from various devices such as PC, Blu-ray 3D™, Sony® PS3, Microsoft® Xbox 360 or 3D TV broadcast system.

Brightness matching
The brightness of a projector will vary throughout its life. To correctly match multiple units, the EH503 has 10x lamp power steps between 80~100% full brightness.

Wired remote
The wired remote connection allows all aspects of the projector to be individually controlled without requiring a line-of-sight to the projector; invaluable when using multiple units during live events.
