A sophisticated proprietary optical system, coupled with a hight
performance zoom lens ensures hight contrast images, superior
uniformity and edge-to-edge definition.
A new 6-segment colour wheel dramatically reduces the so
called “rainbow effect” and gives a better contrast, better
colorimetry and a lower black level to the image.
The  DMD™ chip resolution identifies the projector: 1024x576
pixel for HT 280 model and 1280x720 pixel for HT 300
XTRA-H model. For both models the high contrast ratio deliver
on the screen an even more realistic image.
The renowned DCDi™
 technology is adopted for deinterlacing:
conversion from interlaced to progressive produces a smooth
and natural image, without flickering, loss of vertical resolution
and jaggedness along diagonal lines.
The low-noise ventilation system – with variable speed fans –
ensures appropriate cooling and maximizes projector reliability.
To fully appreciate your new projector we recommend the use
of a good quality screen and surround-sound system. Contact
your nearest authorized SIM2 Multimedia dealer for further
details.
SIM2 carries out comprehensive functional testing
in order to guarantee the maximum product quality.
For this reason, when you start using the product
lamp operating hours may already be at between
30 and 60.
In addition to the regular tests, the Quality Control
department performs additional statistical tests at
the time of shipment.
In this case the packing may show signs of having
been opened, and the accumulated lamp operating
hours may be slightly higher than the hours associ-
ated with the standard tests.
Fig. 1
Using the very latest in DLP™ technology, this projector has
been designed specifically for high quality “Home Cinema”
applications.
Sophisticated digital processing and a wide choice of inputs
enable the connection of a variety of sources such as DVD
players, analogue and digital VCRs, analogue and digital sa-
tellite receivers and personal computers etc.
The long throw zoom lens allows the position of the projector to
be located behind the viewer, thus reproducing a cinema-like
installation 
(Fig. 2).

For rear projection the screen must be translucent.
For front projection, we recommend the use of screens with
low gain specifications (i.e. 1.3 to 2).  The use of high gain
screens should be avoided due to their limited viewing angle,
