WARNINGS AND SAFETY PRECAUTIONS

Please read and follow the safety precautions listed below to ensure the equipment is
free from damage, and to ensure that no injury will occur as a result of improper use.

• Do not insert any object, especially metal or liquids, into the VHD-4402 ULTRA.

• Do not place any objects containing water or any other liquid on top of the

VHD-4402 ULTRA

• Do not place the unit in direct sunlight, near heaters or in extremely dusty or
humid locations

• Do not install this unit outdoors or otherwise exposed to the elements

• Do not place heavy objects on top of the unit

• If the power cord is damaged or frayed in any way, electrical shock and/or fire

may result. Please do not place objects on the power cord, and keep the cord
away from heat-emitting devices. Should the power cord become damaged in any
way, please contact your Runco dealer for a replacement cord.

• Do not remove the cover of the unit for any reason. If any problems arise with the
unit, please contact a Runco dealer or Runco International for service. Removing
the cover will void the warranty.

Safety Tips:

Congratulations on your purchase of the VHD-4402 ULTRA! This processor is designed to work with
either a CRT projector or a fixed-pixel device (DLP, Plasma, etc.), and will provide full aspect ratio con­trol as well as greatly enhanced picture quality. For example, DLP projectors were not initially designed
to be used on wide aspect-ratio screens (16:9 or 1.85:1). The VHD-4402 ULTRA, however, expands
the use of the DLP projector to be able to accommodate Letterbox, anamorphic (16:9) and 4:3 images
on your wide-aspect ratio screen. This allows you to use the full benefit of your widescreen without
having to sacrifice aspect ratio control. When using the VHD-4402 ULTRA with a CRT projector (i.e.
DTV-940), the aspect ratio control feature allows the projector to stay in a single memory, making inte­gration into the system much easier.

The VHD-4402 ULTRA is not only an aspect-ratio controller, but is also scaler with a progressive out­put, which virtually eliminates motion artifacts as a result of interlaced signals. Also, its 10-bit process­ing results in the cleanest, most resolved video images a processor can provide.

This preliminary version of the VHD-4402 you have just received has all of the features noted above,
and has a scan rate output (38 kHz) optimized for the Runco projector you have purchased with it. This
processor will be upgradeable in the future; these upgrades include multiple scan rate outputs and the
ability to optimize the output for either CRT projectors or fixed pixel devices. This upgrade will either be
in the form of an exchange with a fully upgraded unit, or a software upgrade which involves a simple
chip replacement. Please contact Runco for more updated information regarding these upgrades.

The VHD-4402 ULTRA has many great features and benefits that make it a flexible, high-quality
processor. Its many benefits include:

• An adaptive 2-dimensional comb filter that greatly reduces artifacts when using a composite video
signal as an input.

• A Luma edge enhancement circuit makes the edges of objects appear sharper without the ringing
and noise increase associated with traditional sharpness circuits

• A Chroma edge enhancement circuit is included to compensate for lower chroma resolution found in
composite and S-video.

• Inverse Telecine (3:2 pulldown) detection and processing allows the scaler to almost completely elimi­nate interlace artifacts associated with other scalers

• The controller can correctly scale anamorphic, letterbox and 4:3 formats to fit on a wide aspect-ratio
screen, and scale anamorphic formats on a 4:3 screen

• A pass-through connector is supplied for routing HDTV or computer graphics directly to the projector.

• An RS-232 input is provided for easy integration into the automated home theater environment

• A TBC (Time Base Corrector) circuit is provided for unstable sources such as VCR’s.

• A Dual-Screen actuator output for both Widescreens and 4:3 screens is provided

• A simple 7-button remote controls all aspects of operation. One button source selection and aspect
ratio control is also provided via the remote control or the front panel.
