In many cases, this means no
maintenance until your next refresh cycle.
Naturally, there are no lamp burnout problems
during use, so reliability is further increased.
There is also no filter to clean due to carefully
engineered sealed optics. As a consequence,
running cost is dramatically lowered because of
the savings on lamp costs, maintenance labor
and hassle of stocking lamps.

Beautiful Picture Quality for a Long Period
of Time with 24/7 Operation
The rate of brightness deterioration in the LED/
Laser-combined light source is extremely slow
compared to lamp-based projectors. The SOLID
SHINE drive uses a built-in sensor to constantly
detect the intensity of the light source and cor-
rect corresponding changes in white balance.
This all helps to maintain excellent picture quali-
ty for a long period of time. Contrast is out-
standing too, at 20,000:1, and images are
reproduced with a wide dynamic range. There is
no maintenance required because the PT-RZ475
does not use a lamp or air filter. And it has an
efficient cooling system and dust-resistant struc-
ture, and uses a DLP

Heat Pipe Cooling System Maintains Stable
Operation up to 45 °C (113 °F)*

Laser cooling is performed by releasing the heat
to cooling fins, then cooling with a heat pipe
cooling system. This suppresses temperature
rises inside the projector and allows stable
operation up to an ambient temperature of

Image Appears Immediately—No Need for
Cooling after Use
Images do not appear quickly with lamp-based
projectors because the projector requires time to
warm up. With the PT-RZ475, the image
appears almost instantly. There’s also no cooling
time required when turning the power off, so
you can quickly turn the projector on and off as
many times as needed.

Superior Color Reproduction
The LED/Laser-combined light source has a
higher level of color purity than an ordinary
lamp, allowing it to achieve color reproduction
with wider color space. Colors are more vibrant
than those of conventional projectors.

Transmits Digital Signals up
to 100 m (328 ft) with a Single Cable
Equipped with a DIGITAL LINK terminal, the
PT-RZ475 allows transmission of HDMI, uncom-
pressed HD digital video, audio and control sig-
nals (Ethernet, RS-232C) for up to 100 meters
(328 feet) through a single CAT5e (STP) cable
or higher. This simplifies cabling and system
upgrades, making it ideal for ceiling-mounted
and other permanent installations.
