Long-Lasting Reliability
Outstanding Approx. up to 10 Years *
Continuous Operation
This new LED/Laser-combined light source
requires no maintenance for approximately up to
10 years. *
In many cases, this means no
1
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
chip that has a long life.
™
Together, this makes the PT-RZ475 ideal for
24/7 operation.

LIGHT SOURCE LIFE
* 2 The operating temperature range is 0 °C to 40 °C (32 °F to 104 °F) when used in
locations from 1,400 m to 2,700 m (4,593 ft to 8,858 ft) above sea level. If the
ambient temperature exceeds 35 °C (95 °F), the light output may be reduced to
protect the projector.
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
of
rises inside the projector and allows stable
1
operation up to an ambient temperature of
45 °C (113 °F ) *
cooled system also achieves quiet operation of
35 dB *
, enabling viewers to concentrate on the
3
presentation or on quiet movie scenes.
Heat-pipe cooling system
Dust-Resistant Structure with an Airtight
Optical Block
The area between the LED/Laser to the DLP
chip and prism is hermetically sealed to form an
airtight structure for the optical block, the heart
of the projector. This resists the effects of dust
and other particles in the air, and enables use
of the projector in a wide range of environments.
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.

High Picture Quality
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.

In 1-chip DLP
system projectors with conven-

tional lamp, a color wheel is used for time-divi-
sion multiplexing in a method where the human
eye combines the result to achieve a full-color
palette. In the PT-RZ475, this is done by on/off
switching of the LED/Laser-combined light
source. A unique Panasonic power supply circuit
provides time-division multiplexing with ultrafast

Connection Flexibility
DIGITAL LINK—The Single
Cable Solution
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.
