The Panasonic PT-DZ21KU’s unique technical attributes come together in an offering designed to meet the needs of professionals across industry and academia. Achieving up to 20,000 ANSI lumens, the PT-DZ21KU also has an ultra-high 10,000:1 contrast ratio that is achieved via a dynamic aperture mechanism that helps to create more vivid images, according to the comopany. Depending on lamp mode, replacement hours can be a lengthy 2,000 in quad-mode and up to 8,000 in single-lamp-mode. Liquid cooling technology keeps the unit functioning quietly at temperatures up to 113-degrees F. An electrostatic reusable filter helps keep operating costs low. Input terminals include two SDI ports, an HDMI, BNC connections, a serial RGB input, a DVI-D connector, composite video in, LAN connection, and BNC connections for 3D syncing.
Projection Design offers the F85 Series series in the 3-Chip DLP WUXGA space. Featuring an ANSI lumen rating of 11,000, it has a 14,000:1 contrast ratio and a native 1920x1200 resolution. It can accept signals from two DVI-D inputs, two HDMI, two VGAs, an analog signal from five BNC connectors, component, S-video, and a composite input. RS-232 and RJ-45 ports are available for control. The F85 is relevant in almost all installations requiring high brightness, exceptional color reproduction and low total cost of ownership.
Sony’s SRX-T420 projector is built on the company’s 4K digital cinema technology. Ideal for a wide range of large venue applications, the SRX-T420 features 4K resolution, 18,000 lumen brightness, and projects ultra-high definition images with a native resolution of 4096x2160 pixels. Evolved from digital cinema technology, the uprated 4K optical engine delivers a contrast ratio of 12,000:1. A choice of lens options allows the projector to be configured rapidly for smooth, flicker-free 3D projection, while edge blending allows easy creation of even larger images. For example, pictures from two projectors can be seamlessly presented side by side to create an auditorium-filling 7Kx2K panoramic image (overlapped by 1K). Reduced running costs are enabled by a multi-lamp array, with six HPM sources in individual cartridges making lamp replacement easier and safer. Reduced risk of ‘dark screen’ lamp outages is complemented by fail-safe reliability, plus greater operating flexibility with the ability to select the number of lamps lit to meet the needs of different applications and venue sizes. Lengthened lamp-exchange cycles and reduced maintenance requirements contribute further to lower running costs.
I’d like to round out the field of manufacturers with two other manufacturers with a strong base in the video projector market: Canon and Epson. Although these projectors do not meet all the “large venue” criteria, they are worth mentioning. These projectors represent the “top of the line” from both Canon and Epson and are smaller, more cost-effective solutions for larger venue applications.
The Canon REALiS WX520 pro AV compact installation LCoS projector features WXGA+ (1440x900) resolution in a lightweight and compact design. Specs indicate an output of 5200 lumens and a 2000:1 contrast ratio using Canon AISYS technology. Digital keystone provides +/- 20 degrees in both the vertical and horizontal planes. This projector features include four-point keystone adjustment, digital and physical lens shift, image detail adjustments, and controls. The projector is matched with a fixed F-stop lens for projecting 16:10 aspect ratio images. The video projector also includes support for USB memory sticks, JPEG support, and a built-in speaker.
The Epson PowerLite Pro Z8255NL multimedia projector offers 10,000 lumens of brightness for presentations in a variety of venues, including those where ambient light is present. Featuring XGA resolution, 3LCD technology, and a contrast ratio of 5000:1, the Z8255NL delivers projected images for applications such as lecture halls, conference centers, and entertainment venues. Setup and installation are easy with 360-degree projection and includes edge-blending capabilities. The projector provides a variety of connectivity options and a full suite of monitor and control features. This projector ensures easy integration with a variety of devices, plus a fairly low overall cost of ownership. The projector comes in a black casing making it well suited for staging and rental applications. There are a variety of optional lenses to accommodate various throw distances and image sizes.
