❷ Introduction to the Projector This section introduces you to your new projector and describes the features and controls. 1. Introduction General • Three-chips DLP projector with high resolution and high brightness Model name Brightness Resolution PH3501QL PH2601QL 35,000 lm / 40,000 lm (center) 26,000 lm / 30,000 lm (center) 4096 × 2160 (4K) 4096 × 2160 (4K) Aspect Ratio 17:9 17:9 • Superior dust prevention abilities The projector utilizes a circular cooling system when cooling the optical components. It cycles cold air to replace the warm air inside the interior of the airtight case so open air does not touch the optical components. This protects against the device getting dirty with dust and dirt, as well as maintains brightness. * However, it cannot perfectly insulate against dust. • Running cost reduction by using a metal filter With regular cleaning, the filter can be repeatedly used without replacement. On top of reducing running costs, we have implemented this eco-friendly feature so there is no need to dispose of used filters. • 4K element user logo images can be registered 4K element images can be registered and output as background logos in real 4K resolution. Light source · Brightness • Employs a long life laser light source The projector employs a newly developed laser light source offering excellent reliability and redundancy. Since the laser light source has a long life (approx. 20,000 hours), this delivers low cost operation by removing the need for maintenance such as replacing and adjusting the light module over extended periods of time. Furthermore, it reduces the risk of the light source suddenly shutting off and leaving a black screen. • Brightness can be adjusted within a wide range Unlike with ordinary light sources, the brightness can be adjusted from 30* to 100% in 1% increments. * PH2601QL: 40% • [CONSTANT BRIGHTNESS] mode Brightness normally decreases with use, but by selecting [CONSTANT BRIGHTNESS] mode, sensors inside the projector detect and automatically adjust the output, thereby maintaining constant brightness throughout the life of the light module. However, if brightness output is set at the maximum, brightness will decrease with use. Installation • Wide range of optional lenses selectable according to the place of installation This projector supports 7 types of optional lenses, providing a selection of lenses adapted to a variety of places of installation and projection methods. No lens is mounted at shipping from the factory. Contact your distributor for purchasing and replacing these optional lenses sold separately. • Tilt-free, portrait projection This projector can be set to any angle within a vertical 360° range. It can also rotate the picture 90° into portrait orientation, however, it cannot be installed with right or left slant besides the portrait projection. 3
