IAVI - Pro AV Distribution Made Simple

The PT-D4000U projector provides high brightness (4,000 lumens) and a 1600:1 contrast ratio for crisp, high-resolution images in nearly any viewing environment. Panasonic's System Daylight View function makes clear, sharp images possible even in well-lit rooms. To do so, image processing circuit compensates for the loss of color saturation that occurs when light reflects onto the screen from bright surroundings.
is highly affordable.

High Brightness and High Picture Quality
Ultra bright 4,000-lm
The PT-D4000U offers 4,000 lumens of Off On brightness, thanks to the newly developed AC lamp and more efficient reflectors and synthetic mirror. Real-life images are also produced in rooms with the lights turned on.

System daylight view
The system daylight view function uses an image processing circuit to compensate for the loss of color saturation that occurs when light reflects onto the screen from bright surroundings. It is especially effective for producing crisp, sharp images in dark portions containing gradation. The function can be adjusted in three steps.

Full 10-bit picture processing
The use of a full 10-bit image processing system provides smooth tonal expression. For example, skin tones appear natural and true to life.

New IP conversion circuit
The PT-D4000U features a new IP conversion circuit that produces more detailed images than our previous models.

More effective noise reduction
Images are noticeably clearer, thanks to higherperformance frame noise reduction, which lowers image graininess, and improved MPEG noise reduction, which suppresses the block noise and mosquito noise that are common in fast-action scenes.

3D color management system
Compensation provides optimal levels of color saturation, hue, and brightness that were not possible with conventional projectors. Colors approach those of the original image, even on large-screen displays.

Dynamic sharpness control

 The dynamic sharpness control circuit adjusts the video signal waveforms based on the difference in brightness of adjacent pixels for a sharp, clear picture that is relatively unaffected by signal noise.

Excellent reliability
Dual lamp system
The use of two lamp systems increases brightness and eliminates the need to interrupt a presentation if a lamp burns out (in dual lamp operation mode).

Liquid-cooling system
Panasonic's original liquid-cooling system directly cools the DLP® chip, which extends PT-D4000U performance and attains a high level of reliability. It also enables operation in temperatures up to 113 ˚F/45˚C for use in a wider variety of environments, and maintains a more stable performance even in harsh conditions while keeping the operating sound down to a quiet 29 dB*.

Micro cut filter
A filter in the air intake section traps dust particles that are 10 microns* or larger. By capturing approximately 7 times as much dust as conventional filters, it guards against optical blocks and reduces the penetration of dust into to the interior to provide stable operation by, for example, preventing drops in brightness.

AC lamp
Newly developed AC lamps with full 210 watts of power offer excellent brightness and greater reliability than other types. A new lamp drive system also lowers the stress on the lamp electrodes while the lamps are lit. The new lamps have a lifetime of approximately 3,000 hours, which is reassuring for applications where the projector is frequently used. The AC lamps also minimize color irregularities.

Dustproof design with sealed optical block

The effect of dust has been minimized by completely sealing the optical block.The dust-free design helps ensure that this DLP® projector will continue to deliver crisp, sharp, high-resolution images over an extended service life.

Flexible system installation
Lens-Centered Design
A lens-centered, symmetrical design provides flexible system layout, eliminating the need for any special considerations when planning the installation site.

Horizontal/Vertical Lens Shift
A wide adjustment range of the horizontal/vertical lens shift assures distortion free images and adds convenience and versatility. (Horizontal : manual, vertical : powered)

Optional Lenses For Various Venues
Five optional lenses with different throw distances - the same as those used in the PT-D5500U - are available in addition to the supplied lens. These powered zoom/focus lenses enable the projector to perform superbly in an array of projection environments.

Multiple terminals
The PT-D4000U has an array of terminals-two RGB inputs including a 5-BNC connector, serial in/out, one S-video inputs, two remote in, one remote out, DVI-D and control capability-to support a broad range of projection needs HDCP. (High-Bandwidth Digital Content Protection) compliant. Using the serial terminal(RS232C),it is also possible to connect and operate AMX and Crestron control systems with ease.

Web browser control/monitoring and e-mail message alert
Anybody can operate the PT-D4000U by remote control or monitor its status over a LAN network, because it is all done using the computer's familiar Web browser. Furthermore, the PT-D4000U sends an E-mail message to notify the operator when an error has occurred, or a lamp needs to be replaced.

Control panel and wireless remote control
The rear control panel allows for easy operation when the PT-D4000U is set on a desk or floor. New wireless remote control with longer transmission capacity of 98 feet (30 m).

PJLink® compatibility
The LAN terminals support PJLink® class 1 connection. Control with the same specifications is also possible when used in a multi-projector system with projectors of another brand.

Ecology-conscious design
Panasonic works from every angle to minimize environmental impact in the product design, production and delivery processes, and in the performance of the product during its life cycle. The PT-D4000U reflects the following ecological considerations.

• No halogenated flame retardants are
  used in the cabinet.
  
• Quiet operation: 29 dB (in low lamp mode)
  
• The packing case and operating manual
  are made from recycled paper.
  
• Auto Power Save activates standby mode
  when no signal is input.
