Projector features / Preparations
Projector features
This projector is used to project various computer signals as well as NTSC/PAL/
SECAM video signals onto a screen. It requires just a little space for installation
and gets a large image from short distance.
High Brightness
Newly developed 230W UHB (Ultra High Brightness) lamp gives you a higher
brightness image on a screen. The image can be still kept as bright and clean
enough for use in bright rooms.
Low Noise
WHISPER mode is available for reducing acoustic noise to realize quieter
operation. It is perfect for use in low luminance rooms where low noise is more
important than brightness.
Compact Body
Even with its many features, this projector is extremely compact and slim,
which gives you more flexibility and usability to use it where you want.
