Vivitek DU6771BX dual-lamp installation projector


Over the 10 years (next month) of its existence, the Vivitek portfolio has been extended to display, digital signage and collaboration prod- ucts in categories as diverse as consumer and ProAV. Activity at the high-end includes partner- ing with parent company Delta on cube-based video walls and the launch fo a new range of installation projectors. Here, AV News asses Vivitek’s new dual lamp installation projector.


In a move that reaffirms its position as a leading brand of large venue visual display products, Vivitek has launched two new large venue laser projectors, the DK8500Z and the DU8190Z, to accompany the DU7090Z laser projector, launched earlier this year. The DK8500Z offers 4K/UHD resolution and 7500 ANSI Lumens of brightness. The DU8190Z meanwhile is a WUXGA laser light source projector with a strong performance of 10,000 ANSI Lumens brightness. In addition to the new laser projectors, Vivitek has introduced a new dual lamp projector, the DU6771. The dual-lamp technology, interchangeable lenses and advanced display technologies are designed to ensure a bright, high definition digital image with full colour saturation. We put the new dual-lamp model on test I the largest room available to us, with following results.


Applications


Intended for large meeting rooms where brightness and installation flexibility is a key consideration, the DU6771 offers a high brightness of 6,500 ANSI Lumens and WUX- GA resolution with 3,000:1 contrast ratio clear and sharp images. Before we go into detail, let’s look at the ra- tionale behind this product. First why would a customer want a dual lamp projector? If your customer is, for example, a conference centre, the projector is a mission critical device. With dual lamps, the presentation will continue, even if a lamp fails. with the remaining lamp. Some dual lamp projectors offer 24/7 capability, for example in digital signage applications, where lamp relay mode allows each lamp the time required to cool between duty cycles. Finally, installation space is still a consideration and dual lamp


technology can often offer more compact and space saving designs and lower weight than the laser models now popular in this sector. That is not to say that the DU6771 is any particular lightweight, or slight of form. For a street price (AV Partsmaster) of £ 2,699.00 ex VAT you get a lot of projector for your money. The DU6771’s chassis and case is sharply designed and manufactured and would look solidly professions in any installa- tion context. With the central interchangeable lens and side mounted controls, the DU6771 is convenient to use in both table-top and ceiling mounted configurations. While not excessively heavy for this class of projector, we would recommend installing the unit with a colleague.

Set-up


Installation flexibility is assured with the choice of eight interchangeable lens options with a quick touch lens release design for easy removal and reinstallation. The moto- rised zoom, focus and lens shift features allow for easy adjustment and movement. Furthermore, image adjustment is made eas- ier with 4-corner and keystone corrections. HDBaseT allows for digital image and control signals to be sent up to 100m over one single network cable, making installations cost-effi- cient and straightforward.


Installation proved to be straightforward and the projector was up and running in less than 10 minutes. For situations where the project is to be used in a variety of locations. A Lens Positioning Memory (LPM) feature enables up to 10 user assigned settings for lens position,
