IRVINE, Calif., March 3, 2009 — Mitsubishi Digital Electronics America’s Presentation 

Products Division, known for award-winning, high-quality, high-definition presentation and 

display products, today announced its new XD221U classroom projector.  With a 10-watt speaker 

and audio mix capability, closed captioning decoder, user-friendly menus, and low cost of 

ownership, Mitsubishi’s XD221U offers a rich combination of audio-visual features that makes 

teaching more effective with technology that is easy to use.   

 

“Teachers and trainers capture more attention and have greater impact when using multimedia 

technology, and our new XD221U makes presenting easier than ever,” said Wayne Kozuki, 

product manager, Mitsubishi Digital Electronics America’s Presentation Products Division.  “The 

audio features enhance the teachers’ ability to make the subject interesting not only visually, but 

also through clearer sounds and audible information.” 

 

Mitsubishi’s XD221U is designed with two separate 3.5mm audio inputs and a special built-in 

audio mixer so the projector can simultaneously project audio from two sources, such as a DVD 

and a third-party wireless microphone.  Unlike any other projector available on the market today, 

the XD221U’s “Audio Mix” feature allows users to adjust the volume levels of each input for its 

10W built-in speaker.  With this uncommon configuration, an instructor can orally interject key 

points during a presentation and be heard over the video.  

 

“I remember sitting in class trying to hear a teacher speak over the volume of an educational 

program that we were watching, and the audio of the material tended to be louder than the 

teacher’s voice,” said Kozuki.  “With the XD221U, teachers can now clearly point out particular 

details while the audience hears the other audio source at the same time.  Students will pay closer 

attention, be less distracted, and might even learn a little better.”
