When the speaker is not in use, the projector has an ultra-hushed noise level of only 26 dBA in
low mode, so students hear the teacher and not the annoying hum of a fan. It also offers closed
captioning from a supported source. With a touch of a button, the built-in decoder transforms
words into subtitles projected on the screen, an important function for hearing-impaired students.
In order to lessen the impact on natural resources, Mitsubishi has engineered energy-efficient,
earth-friendly features into all of its new projector models. They have a low standby power mode
using less than one watt of power, lead-free solder on all printed circuit boards, and are paint free.
The XD221U blasts a rated 2300 lumens, ample brightness for well-lit classrooms, and is a native
XGA (1024 x 768 pixels) resolution projector that uses Texas Instruments' DLP® technology that
is filter-free and helps decrease dust accumulation. Eliminating the filter saves on maintenance
costs, and a lamp-life rated to up to 4000 hours (in low mode) reduces the need for lamp
replacement. A convenient top-access lamp design saves time and money during infrequent lamp
replacements. The projector also features BrilliantColor®, which creates clear, vivid images from
a computer or video signal.
Intuitive, easy-to-use functionality is very important to many non-technical users, so Mitsubishi
has a simplified menu bar that includes seven basic features and a customizable option to allow
teachers to add a particular feature to the menu. This new easy menu helps reduce confusion
menu customization creates a menu bar for what teachers want and use most in a classroom.
The new XD221U includes dual 15-pin computer inputs as well as S-video and RCA video inputs,
so users can switch between a computer presentation and video with just a press of a button. It
also includes a built-in RJ-45 port for remote operation and management over a LAN, WAN or the
Internet.
Mitsubishi's new projector is ultraportable at only seven pounds and has important security
features with password menu and display locks, plus an anti-theft hook design that locks the
projector in place to help deter theft. It has an RS232 connection for compatibility with third
party control devices and support for a computer loop out for external monitor display.
