INTRODUCTION
The VX-4c/VX-6c projector is a professional quality
DMDTM projector that uses Digital Light ProcessingTM
(DLPTM) technology from Texas Instruments to achieve
high-brightness multimedia and video projection. The
VX-4c/VX-6c is compatible with standard international
video formats and can interface with IBMTM-compatible
PC, MacintoshTM computers and high-definition (DTV)
decoders. The VX-4c/VX-6c is ideal for use in both large
and small home theaters; performing exceptionally well
in venues with ambient light.
The features of the VX-4c/VX-6c include:
The VHD Ultra Controller for optimum picture quality when using NTSC sources
1280 x 1024 native resolution, with other resolutions fully scaleable
3000 ANSI lumens light output (6000 ANSI VX-6c)
Constant height aspect ratio control up to 2.35:1 screens
Interchangeable lenses for screen widths up to 500 inches
Memory for up to 99 custom “Memory Banks” (source setups)
Intuitive on-screen menus or hidden direct control
Modular design for easy servicing.
How The Projector Works?
The VX-4c/VX-6c can accept data/graphics and video input signals for projection on to front or
rear flat screens. High brightness is generated by an internal 700W (1200W VX-6c) Xenon arc
lamp, then modulated by three DMD (digital micromirror device) panels that provide digitized
red, green or blue color information. Light from the “on” pixels of each panel is reflected, con-
verged and then projected to the screen through a single front lens, where all pixels are perfectly
superimposed as a sharp full-color image.

INTRODUCTION
ANAMORPHIC LENS
DLP™ projectors use a small device called a DMD™ (Digital Micromirror Device) to create the
video image. DMDs are designed in aspect ratios ranging from 4:3 (standard) and 16:9
(widescreen), to 5:4 (digital cinema). Understanding that more and more home theaters are
designed using 16:9 or cinemascope projection screens (similar to your local Cineplex's), Runco
has developed an anamorphic lens system to make the 5:4 DMD fully compatible with a home
theater that has 16:9 and 2.35 screen formats.
The Runco Anamorphic Optical System elevates the image quality of a 16:9 picture to a higher
level. This system consists of two components; one being the controller and the other the anamor-
phic lens. The first component is Runco's award-winning Vivix™ VHD™ Ultra Controller with
10-bit processing which is used to scale the video signal to mach the native resolution of the pro-
jector. The second part utilizes one of three anamorphic lenses that optically stretch the image to
a 16:9 or 2.35 aspect ratio.
The advantages of using the anamorphic lens system is that it takes advantage of the entire mir-
ror array on the DMD™ resulting in a higher resolution picture. The result is a high-resolution
picture in a big screen format for the home theater. Another benefit of employing all the mirrors
on a DMD™ is 25% greater light output for an increase in picture brightness. Runco's industry-
renowned controller helps to trigger the electronic corrections for the stretched image and pro-
vides four geometrically correct aspect ratios - 16:9 widescreen, letterbox, 4:3 and VirtualWide™.
HDTV is also geometrically correct and has higher resolution. The Anamorphic optical systems
include an Anamorphic lens, the lens mount assembly, and an Anamorphic Vivix™ Controller.
The Anamorphic Optical System is the ultimate way to maximize resolution and will significant-
ly shorten the throw distance of any Video XTreme™ series projector it is used with. Consult the
specification sheet of the projector for specific throw distance calculations.

This section explains how to install and set up the projector. If you are familiar with the projector and want to
quickly set it up for temporary use, follow the Quick Setup instructions below. For a more complete setup, fol-
low the instructions and guides covered in the remaining subsections.
NOTE: 1) The lens is not mounted when the projector is shipped from the factory. For instructions on how to
install or replace a lens, refer to 4.4, Replacing the Lens.
2.1 Quick Setup
Follow these steps for quick setup of the projector in a standard floor mount position.
STEP 1 Position the Projector
Set the projector at the expected throw distance (projector-to-screen distance) and vertical posi-
tion. Make sure that the projector is level from side-to-side.
STEP 2 Connect a Source
Locate the main input panel at the rear of the projector. The lower left area, labeled INPUT 1,
accepts an RGB input via BNC connectors. The upper right area (assuming a video decoder is
installed) accepts a composite video at INPUT 3 or S-video input at INPUT 4. Connect your
source to the appropriate panel connectors.
STEP 3 Connect the Line Cord to AC Power
Connect the projector’s 13 amp high-current rated line cord to the AC receptacle at the lower right
corner of the projector and to AC. Input power required is 100 - 240 VAC, 50 to 60 Hz @ 11.5
amps (@ 100 V). Use only a high-current 13 amp rated cord. See Section 5.
WARNING
DO NOT ATTEMPT OPERATION IF THE AC SUPPLY AND CORD ARE
NOT WITHIN THE SPECIFIED VOLTAGE AND POWER RANGE.
STEP 4Turn the Projector ON
Using either the built-in or remote keypad, press and hold for approximately 1 second to
turn the projector on (or press ). Let the projector warm up for about five minutes.
The POWER LED, located in the lower right corner of the rear input panel, should glow a steady
green.

INSTALLATION AND SETUP
2.2 Installing The Lens
A variety of lenses are available to accommodate different throw distances and specific types of
installations. See page 2-10 for details. To change/install a lens, follow the steps below.
NOTES: 1) You will need a 9/64”(3mm or 3.5mm) hex socket ball driver (supplied with projec-
tor) or allen wrench for this procedure. 2) “Top” or “bottom” references assume a non-inverted
projector, as illustrated. 3) If you are installing a lens, first make sure its Lens Adapter is present
on either the lens or projector. Such an adapter/flange secures to the projector in the same man-
ner as the flange described below, but accommodates a screw-mount lens.
STEP 1Turn off the projector, cool, and unplug.
Before removing or installing a lens, turn off the
projector and allow it to cool for five minutes before
unplugging. Make sure that the lens cap is on.
WARNING
Unplug the projector.
Install the lens cap.
STEP 2Loosen the 3 lens mount screws
IF FIXED LENS: Use the hex socket ball driver
provided with the projector to loosen the 3 lens mount
screws that secure the lens flange to the mount-loosen
these screws only, do not remove.

INSTALLATION AND SETUP
 IF ZOOM LENS: Access to the 3 lens mount
screws is likely blocked by the toothed zoom ring
in front of it. First rotate the zoom ring by hand
until its 3 access holes align with the screws, then
insert the hex socket ball driver through the holes
to loosen the screws-do not remove. See figure to
the right.
STEP 3Rotate the lens barrel slightly
Using both hands, rotate the lens barrel counter-
clockwise until the screw heads align with the larg-
er end of their slots on the lens.

INSTALLATION AND SETUP
STEP 4 Pull lens assembly out
Carefully pull the lens assembly straight out of the projector
and set aside.
STEP 5Install new lens assembly
IMPORTANT:Remove the rear (smallest) lens cap from the new
lens. Make sure the front lens cap remains on during installation.
Align the large cut-out area on the lens flange to the bottom of the
lens mount (which has a matching cut-out). The 3 lens assembly slots
should align with the lens mount screws so that the screw heads will fit
through the large end of the slots (see Orientation figure).
NOTE: On most lenses, a small extra “keying” slot located at approxi-
mately 2 o’clock on the lens flange will align with a set screw in the same
location on the lens mount, preventing the lens from being installed in the
wrong orientation. If the lens flange does not seem to fit into place over all
screws, try rotating the lens assembly in one direction or another.
 With the lens assembly aligned and the screws inserted through the flange, use both hands to
rotate the lens barrel clockwise until the lens mount screw heads lock into the small end of the
lens assembly slots.
 Secure the 3 lens mount screws.
STEP 6Reposition the projector for new lens
Remove the front lens cap and reposition the projector closer or further from the screen as nec-
essary for the screen and the new lens type (refer to Throw Distance section 2.6). In a permanent
installation, always use the appropriate throw distance formula to calculate the distance accurate-
ly Power up and test. Adjust offsets as necessary.

INSTALLATION AND SETUP
STEP 6Adjust Image
ZOOM: With the input image displayed, rotate the textured ring on the
lens barrel to increase or decrease the image size (this requires a zoom
lens). If you do not have a zoom lens or you can not adjust the image
enough, the projector may not be positioned at the proper throw distance
for your screen size. Power down, unplug the projector and move it
towards or away from the screen.
FOCUS: At the lens opening, turn the focus tab to focus the image

INSTALLATION AND SETUP
2.3 Installation Considerations
Although this projector delivers a high brightness quality output, final display quality could be
compromised if the projector is not properly installed. This subsection discusses issues you
should consider before proceeding with a final installation. Even if you do not intend to use the
projectors in a fixed and permanent installation, this subsection will help you to better understand
what you can do to enhance display performance.
Lifting
For any new installation, you will likely have to safely lift the projector into place. Keep in mind
that the projector is quite heavy, and the aid of a CO2or other type of mechanical lift is highly
recommended.
2.4 Additional Considerations
Here are some other considerations and tips which can help you improve your installation:
Keep the projector away from devices that radiate electromagnetic energy such as motors and
transformers. Common sources of these are slide projectors, speakers, power amplifiers, ele-
vators, etc.
For rear screen applications, less space is required if a mirror is used to fold the optical path.
Choose the right screen size for the application:
UAs screen size increases, magnification increases and reduces brightness. Select a screen
size which is appropriate for the theater, but not larger than what is required.
UInstalling a large screen in a small room is similar to watching television close up; too
large a screen can overpower a room. A good rule of thumb is to be no closer than 1.5
times the width of the screen.
ULarger screens require greater attention to lighting conditions.
2-6
Press to refine other display parameters, if necessary. See 3.5 Using Inputs and Memory Banks if you want
to work with other source inputs or defined memory banks.
You may want to reduce initial setup time by starting with an “Auto Setup”. The projector will automatically
optimize a variety of display settings according to the incoming source detected. You can then re-adjust these
settings at any time, if desired.
Menu
Ventilation is an important factor when preparing a projection room. The ambient
temperature should be kept constant and below 35°C (95°F). Keep the projector
away from heating and/or air conditioning vents. Changes in temperature can
cause drifts in the projector circuitry that may affect performance.

The VX-4c/VX-6c 720P system offers high definition resolution in a 16:9 format, while providing multiple
aspect ratio selection. Without the use of an anamorphic system.
The VX-4c/VX-6c 960P system provides a 26% increase in brightness and resolution over the base 720P con-
figuration. (Using a 1.33 x Anamorphic lens)
The VX-4c/VX-6c 1024P system yields digital cinema resolution by employing every available pixel for a max-
imum picture clarity and brightness. (Using a 1.42 x Anamorphic lens)
The VX-4c/VX-6c 1024P/2.35:1 system also makes the maximum resolution fully available, on a 2.35:1 aspect
ratio screen. All other common aspect ratios are selectable using the constant height approach. This system was
created for the true cinemaphile owning a theater with a cinemascope screen. (Using a 1.90 x Anamorphic lens)

Always consult this section when planning a projector installation. See also section 2.7 and 2.8, Projector
Position and Mounting.
Calculating Throw Distance
Correct throw distance depends on the screen size and lens present-the larger the image needed,
the greater the distance you must allow between the lens and screen. Once you know the screen
size and lens type present, you can calculate the precise throw distance you require by using the
appropriate formula as found in this appendix.
Throw distance is the distance between the projector front feet and the screen. This measurement
is not necessarily parallel to the floor-i.e., the projector and screen may be inclined.
NOTE: If your projector is tilted
up or down in relation to the
screen, as is sometimes the case
for large venues or elevated
installations, throw distance still
represents the smallest measure-
ment between the screen and
front feet centers.
Pre-calculated throw distances for the complete range of lens types and screen sizes appear in the
charts and graphs on the following pages. Refer to these examples to quickly determine the prop-
er throw distance (±5%) for your installation and lens.
NOTE: Variable operating ranges for zoom lenses appear in graphs only.

INSTALLATION AND SETUP
2.6 Vertical & Horizontal Position
THE VERTICAL POSITION of the projector in relation to the screen also depends on the size
of the screen and the lens type. Correct vertical position helps ensure that the image will be rec-
tangular in shape rather than keystoned (having non-parallel sides) and that image focus and
brightness both remain optimized.
In addition, vertical position of the image can be manually offset-that is, moved up or down-by
turning the top screw on the front of the projector (the bottom screw if the projector is ceiling
mounted). The range of adjustment is roughly 130%, depending on the specific lens you are using
and whether or not you are also offsetting horizontally. See Table 1 for the percentage of the
image that can be displayed above and below the center of each type of lens designed for this pro-
jector. These image offsets are also illustrated below (Fixed Lenses) and on the following page
(Zoom Lenses).

Maximum Vertical Offsets (ZOOM LENSES)
NOTES: 1) If you cannot raise or lower the image enough using
mechanical vertical offsets, try adjusting V-Shift in the Scaling
Parameters menu (see 3.6, Adjusting the Image). 2) If the image
becomes keystoned or exhibits uneven brightness, the projector
may simply be too high or low in relation to the screen.
3) Recommended offset ranges can be exceeded, however this may
affect image quality. 4) Simultaneous horizontal and vertical
offset limits the adjustment range of each.
THE HORIZONTAL POSITION of the image can be offset-that is, shifted left or right of lens center-by
turning the bottom screw on the front of the projector (the top screw if the projector is ceiling mounted). The
maximum horizontal offsets for the lenses designed for this projector is shown on the following page. For this
projector, this value expresses the maximum percentage of the image that can be projected to one side of the lens
center (roughly 80%, depending on the lens).

INSTALLATION AND SETUP
2.7 Mounting
For typical front or rear floor mounts, mount the projector on a secure table
or cart. Take care with a mobile cart-avoid sudden stops, excessive force and
uneven surfaces that may cause the projector and cart combination to over-
turn.
The table or cart should be reasonably level. Fine adjustments to the projec-
tor level can be made by adjusting the height of the projector legs.
Special Mounting
Note that projector can be rotated and mounted at any vertical angle-i.e., you can tilt the face of
the projector up or down as much as desired for your installation. The side-to-side tilt, however,
must not exceed 15° (see below). This limit ensures that the arc lamp in the projector operates
properly and safely. Always make sure that exhaust air from the projector does not vent towards
the lens, otherwise you may detect heat waves in your projected image.
Horizontal and Vertical Tilt Ranges
You must use the proper ceiling mount fixture or stacking kit for your projector. For more infor-
mation, contact your Runco Dealer.

Folded Optics
In rear screen applications where space behind the pro-
jector is limited, a mirror may be used to fold the opti-
cal path. The position of the projector and mirror must
be accurately set-if considering this type of installation,
call your Runco dealer for assistance.
2.9 Source Connections
The rear panel of the projector provides standard input panels to which you may connect a vari-
ety of sources. See below - the lower left area (INPUT 1) typically accepts an RGB signal from
an external RGB source (such as the VHD Ultra Controller), or it can also be used for YPbPr sig-
nals from DTV sources. The upper right panel-the Video Decoder Module-accepts only compos-
ite video at INPUT 3 or S-video at INPUT 4 from devices such as VCRs, laser disc players or
DVD players. There are also several optional interfaces available for connecting other sources at
INPUT 2. Such an option installs in the upper left area, just below the audio connectors. For any
input, including the optional inputs, audio with loop through connects at the audio input panel
located between the license label area and INPUT 2.

INSTALLATION AND SETUP
RGB Signals
INPUT 1 provides 5 BNCs (connectors) for linking to a variety of sources. The typical connec-
tion would be to an RGB source such as the VHD Ultra Controller, computers or DTV decoders
with an RGB output. This projector supports multiple sync types with RGB signals: sync-on-
green, composite sync, and separate H & V syncs.
NOTES: Depending on the source, you may need a custom adapter cable that has BNC connec-
tors at the projector end and a different type of connector at the other (such as a 15-pin “D” con-
nector for computer sources). Contact your Runco dealer.
Connect the SYNC BNC input(s) first. Then connect the red, green and blue source outputs to the
RED, GREEN, and BLUE BNCs on the INPUT 1 panel. If the source uses sync-on-green, only
the red, green, and blue connections are required. If the source provides a composite sync output,
connect it to the SYNC input labeled HOR/COMP. If the source provides separate horizontal
and vertical sync outputs, connect horizontal sync to the SYNC input labeled HOR/COMP and
connect vertical sync to SYNC input labeled VERT. See below.
NOTE: To connect YPbPr signals, such as from analog HDTV sources, to INPUT 1, use the red,
green and blue BNCs as described in YPbPr Signals later in this section.
Connecting RGB Input
AUDIO for INPUT 1: To control audio levels in an audio/visual system, connect pre-amplified (line level) audio
inputs to the “IN 1” left and right channel audio inputs located near the top left corner of the rear input panel.
Then connect external audio amplification equipment to audio “OUT” for sound output. Audio connection
cables require standard RCA type phono plugs.
