Description
The projector accepts data/graphics and video input signals from a variety of
sources for projection onto flat, curved, or rear projection screens. System
inputs are processed to provide separate red, green, and blue image components for projection through the projector’s three front lenses. The three
primary color components converge on the projection screen to provide a
high quality display output.
Sophisticated processor-based logic and control circuitry provide many of
the automatic features available on the MP-8 and MP-9. This circuitry
interfaces with the keypad and remote control to provide projector control
by the user, such as:
❑ turning the projector on or off
❑ switching input sources
❑ adjusting all display settings such as contrast, brightness, and size
❑ correcting for display effects and input noise
❑ displaying projector operating status screens and on-line help
❑ controlling projector operating settings
1.1
Should projector servicing be required, service personnel can use the keypad
to make service adjustments and alignments. In some cases the projector
may be serviced without accessing the projector’s internal circuitry. Projector
settings, usually different for different sources, are stored in memory for
each individual source. These settings are retained until changed by the user,
even if power is removed from the projector.
Construction ➤ The projector body is comprised of a sturdy metal chassis, metal top covers,
and durable plastic side covers. The front top cover can be temporarily
removed to access the keypad and align the lenses. The rear top cover and
rear panel are removable for servicing and projector upgrading.
Expandability ➤ Madrigal Imaging projectors can be expanded or upgraded to include addi-
tional features, accessories, and input options; these include a variety of
quick plug-in interface modules to suit the input devices you are using, a
signal switcher, a video decoder, a ceiling mount, and floor mount accessories. For more information or if you need assistance for upgrading your
projector, contact your dealer or Madrigal Imaging.

INTRODUCTION
1.2
Section 2
Installation & Setup
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 in section 2.1. For a complete
setup, skip section 2.1 and follow the instructions and guides covered in the remaining subsections.
2.1 Quick Setup Follow these 7 steps for quick set up of the projector:
Step 1 ➤
Position the Projector
To perform a quick setup, the projector must be positioned so that the throw
distance is the same as that used during the most recent optical alignment;
otherwise a detailed setup is required. The throw distance is the distance
between the center lens on the projector and the center of the projection
screen. See Appendix F and Appendix G for more information. Note: If an
optical lens alignment is required, refer to section 2.8, Optical Alignment.
Step 2 ➤
Connect the Power Cord
Plug the AC line cord into the line input unit on the lower front panel of
the projector. Plug the three prong end of the line cord in a grounded AC
outlet. Notes: 1) Input voltage must be between 90 VAC and 264 VAC.
2) Ensure the line cord is the proper type for the AC receptacle.
Step 3 ➤
Connect a Source
Connect a source to the projector’s RGB input. Ensure the source is on and
properly connected.
Step 4 ➤
Access the Keypad
Remove the projector’s front top cover to access the keypad. See page 3-2.
Step 5 ➤

Screen Type ➤ Screen type is a very important factor when designing a projection system.
Inexperienced users or installers should always consult their dealer when
deciding on screen type. The following guidelines may be helpful to
understand the differences between screen types.
Front Screen Installations
There are two basic screen types: flat and curved. The choice between a flat
screen versus a curved screen is dependent on audience viewing angle and
screen gain. There is always a trade-off between viewing angle and gain.
Viewing angles for both screen types are illustrated in Figures 2-1 and 2-2.
Flat screens offer a gain of about 1 with a viewing angle just less than 180°.
Incident light reflects equally in all directions so the audience can see the
display from various angles. Because of the lower gain, flat screens are more
effective when ambient lighting is reduced.

• Usually good ambient light rejection. • Installation cost is usually higher.
• Less space is required behind the screen
than other rear screen installations.
ADVANTAGES CONSIDERATIONS
• Projector is completely hidden from the audience. • Requires separate room.
• Usually good ambient light rejection. • Installation cost is usually higher.
INSTALLATION & SETUP
2.3
Figure 2-2. Audience Coverage with Curved Screen
Curved screens have gains larger than 1 and viewing angles much less than
180°. Most curved screens have different horizontal and vertical viewing
angles. Incident light does not reflect equally in all directions. The reflected
light concentrates in a conical volume or “viewing cone”. Audiences within
the viewing cone see a brighter image than that from an equal area on a flat
screen. Audiences outside the viewing cone see a dimmer image.
To summarize, curved screens are better suited for brightly lit rooms where
the audience is situated within the viewing cone. Flat screens are best suited
when a wide viewing angle is required and ambient room lighting (near the
screen) is low.
Note: Screen Gain is defined in Appendix A, Glossary.
Rear Screen Installations
There are two basic types of rear screens: diffused and optical. A diffused
screen has a surface which spreads the light striking it. Purely diffused
screens have a gain of less than 1. The main advantage of the diffused
screen is its wide viewing angle, similar to that of a flat screen for front
screen projection.
Optical screens take light from the projector and redirect it to increase the
light intensity at the front of the screen. This reduces it in other areas. A
viewing cone, similar to that of a curved front screen installation, is created.
To summarize, optical screens are better suited for brightly lit rooms where
the audience is situated within the viewing cone. Diffused screens are best
suited when a wide viewing angle is required but there is low ambient
room lighting.

Screen Size and ➤
Throw Distance
Screen size and throw distance are interrelated. (See Appendices F and G.)
As screen size increases, the distance between the projector and the screen
also increases. During projection room design, make sure that the room
can accommodate the required position of the projector for the screen size
you need.
Screen Size
Screen sizes vary according to model and lens type. (See Appendices F
and G.) Choose a screen size which is appropriate for your application. If
the projector will be used to display text information it is important that
the image size allows the audience to clearly resolve all text. The eye usually
sees a letter clearly if eye-to-text distance is less than 150 times the height of
the letter. Small text, located too far from the eye, may not be legible at a
distance even though it is projected sharply and clearly on the screen.
To fill a screen with an image, the aspect ratio of the screen must be equal
to the aspect ratio of the image. The aspect ratio of an image is the ratio of
its width to its height. Standard video from a VCR has a 4:3 or 1.33:1
aspect ratio. For example, to display a VCR output with a 4:3 aspect ratio
onto a 10 foot (3m) high screen, the width of the screen must be at least
13.3 feet (4m).
Note: Screen size is often specified as diagonal size. Screens specified by diagonal
size have aspect ratios of 4:3. Screens with other aspect ratios are not typically
specified by diagonal size.
Throw Distance
The throw distance (projector-to-screen distance) must be determined for
every new installation. Throw distance, the distance between the projector’s
center lens and the center of the screen, is based on screen size. As screen
size increases, the distance between the projector and the screen increases.
Make sure that the room can accommodate the required position of the
projector for the chosen screen size.
Once your screen size is known you can determine the required throw distance for your projector model and lens by using the formulas in Appendix
G and tables in Appendix F.
Notes: 1) Calculated values are for reference only. It is good practice to simulate
the setup to determine the necessary throw distance. 2) Display size is affected by
input signal characteristics. Once the projector is set, use the Size function to fine
tune display size.
Throw distance and projection angle: Keep in mind that the ability to
properly focus all areas of the image is limited if a significantly tilted
projector is too close to the screen.
INSTALLATION & SETUP
2.5
Lighting ➤ Proper lighting is another important factor when designing a projection
room. Visiting a movie theatre can give you an idea of what makes a good
projection environment. All walls, floors and furnishings are dull colored
and non-reflectively finished. Every effort should be made to create the best
environment for your system.
When designing a projection room, try to avoid white, reflective ceilings
and non-directional lighting such as fluorescent lights. The white ceiling
spreads the light which makes the room appear brighter. You want to keep
the lighting and reflections to a minimum. Spot lighting is a better way to
obtain illumination. Installing light dimmers allows you to control your
lighting environment.
Outside windows are undesirable in any projection environment. A small
crack between curtains on a sunny day can severely wash-out an image.
Make sure that curtains are opaque and fit snugly. Some curtains can provide up to 100 percent blockage of outside light. Pay close attention to the
curtain material facing inside the room. It should have a matte finish.
Even with no external light at all, reflections from room surfaces can
degrade the image. Light from the screen should be absorbed by surfaces so
that it will not be reflected back to the screen. Keep reflective surfaces to a
minimum.
To minimize the effects caused by unwanted light from door and aisle ways,
carefully choose the position of your projector and screen. Figure 2-3 shows
an installation where poor screen placement has allowed too much unwanted
light to enter the screen. In Figure 2-4, the screen and the projector are
positioned so that unwanted light is minimized.

Considerations
Here are some other considerations and tips which can help you improve
the design of your projection system.
❑ Proper ventilation is important. 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 which may affect performance.
❑ Keep the projector away from devices which radiate electromagnetic
energy such as motors and transformers. Common sources of these
are slide projectors, speakers, power amplifiers, elevators, etc. Keep 35
mm slide projectors at least 2 feet away from the projector. Even if both
are not used at the same time, the magnetic fields created by the slide
projector can cause permanent magnetization of the projector.
❑ For rear screen applications, less space is required if a mirror is used to
fold the optical path.
❑ Choose the right screen size for your application:
• As screen size increases, magnification increases which reduces brightness. This reduces the contrast ratio which affects legibility. Sharp
defined edges become soft and fuzzy. Consider whether screen size is
more important than these other vital picture characteristics.
• Installing 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 two times the height of the screen.
• Larger screens require greater attention to lighting conditions.
❑ When laying out your projection room, consider positioning the projector
and screen in a manner which will achieve maximum audience coverage
and space efficiency. For example, placing the screen along the larger wall
in a rectangular room will reduce audience coverage. Figure 2-5 shows two
examples of how audience coverage is maximized.

This jumper setting is important if the keypad is configured for remote
operation. There are two keypad protocols: A and B. These protocols are
available to allow two projectors in the same room to be independently controlled by separate remote keypads. The protocol setting of the keypad must
match that set in the projector’s Keypad Options menu ( ). For
more information about keypad protocols, refer to the Remote Control
Options entry in section 3.7, Utility Features.
JP2
This jumper must always be set between pins 1 and 2 as shown; otherwise,
the projector will not respond correctly to keypad commands.
JP3
This jumper must always be set between pins 1 and 2 as shown; otherwise,
the backlit feature will be disabled and the projector will not respond
correctly to keypad commands.
JP4
The JP4 jumper setting sets the keypad type. If you are converting the keypad to an IR remote, move the JP4 jumper from between pins 2 and 3 to
between pins 1 and 2.
Step 3
For an IR remote keypad, place four AA size, 1.5V alkaline batteries in the
compartment ensuring that the +/– orientation of each battery is correct.
Position the compartment door into place.
For a wired remote keypad, an optional accessory cable (#03-001106-02P)
is required. Plug the cable into the cable connector then position the door
into place. Plug the cable jack into the remote jack input on the projector.

Installations
Floor Mount
Mount the projector on a secured table or cart. Position the projector at the
chosen room location with the projector pointing towards the center of the
projection screen. The angle of projection, combined with the tilt angle of
the screen should direct the reflected image towards the center of the audience. It is recommended that the difference between the projection angle
and the screen tilt angle (within a common reference) be less than 15°.
Refer to Figure 2-9.
Figure 2-9. Floor Mount Installation
You can adjust projection angle and level by adjusting the height of the
projector legs. See Figure 2-10.
Figure 2-10. Leg Adjustment
Ceiling Mount
Mounting the projector to the ceiling requires the use of a projector ceiling
mount fixture. The fixture is shipped from the factory in kit form (with
assembly instructions) for assembly and installation by the dealer/installer.
For more information, contact your dealer or Madrigal.
INSTALLATION & SETUP
2.12
Position the projector so that it is pointing toward the center of the projection
screen. The angle of projection combined with the tilt angle of the screen
should direct the reflected image towards the center of the audience. It is recommended that the difference between the projection angle and the screen tilt
angle (within a common reference) be less than 15°. See to Figure 2-11.
Figure 2-11. Ceiling Mount Installation
Instructions for adjusting projection angle are provided with the fixture kit.
For more information, contact your dealer or Madrigal.
Rear Screen ➤
Installations
When installing a rear screen system, the vertical positioning of the projector is dependent on the type of rear screen being used. There are two basic
types of rear screens: optical and diffused.
Optical Rear Screen Systems
If the system includes an optical rear screen, mount the projector along the
center axis of the screen as shown in Figure 2-12.
Figure 2-12. Optical Rear Screen Installation

Projection Angle = 0
INSTALLATION & SETUP
2.13
Diffused Rear Screen Systems
If the system includes a diffused rear screen, floor mount or ceiling mount
the projector so that the image is directed to the center of the audience.
Projection tilt should be less than 15°. See Figure 2-13.
Figure 2-13. Diffused Rear Screen Installation
In situations where the space behind the projector is limited, a mirror may
be used to fold the optical path as illustrated in Figure 2-14. If a diffused
screen is used, the projection angle Ø should be less than 15°. If an optical
screen is used, the optical path between the mirror and the screen should be
perpendicular to the screen. Much attention must be given to the positioning of the projector and the mirror. This can be quite difficult for installers
unfamiliar with this type of installation. It is recommended that your dealer
or an experienced installer perform the installation.
Note: When using a mirror as shown in Figure 2-14, the calculated throw
distance (D) is the summation of D1 and D2.

Connections
The projector includes a built-in RGB input interface for connection of
external RGB sources and audio equipment. This input interface is shown
in Figure 2-16. The built-in interface is not removable.
Figure 2-16. Projector Input Slots
Optional interface modules are available to accommodate other signal
types. These include a Composite/S-Video Module, an HDTV Input
Module, and a PC Analog Input Module. Any one of these can be installed
in slot 2. A Multi-Standard Decoder may be installed to add four additional
inputs to the system (“slots” 3 to 6). To further increase the number of
inputs, a signal switcher may be connected to the RGB interface in slot 1
to add 8 more sources to the system (9 switcher inputs replace one RGB
input). Other switchers may be connected to the first switcher for more
inputs. Brief descriptions of the above mentioned optional modules are
given in Appendix H, Interfaces. For additional details, contact your dealer
or Madrigal.

The RGB interface allows connection of an RGB source having one of the
following sync types: sync on green, composite sync, or separate H & V sync.
To connect a source, connect the red, green, and blue outputs to the RED,
GREEN, and BLUE inputs on the interface. If the source uses sync on green,
no additional cables are required. If the source provides a composite sync output, connect it to the HOR/COMP input. If the source provides separate
horizontal and vertical sync outputs, connect the horizontal sync signal to the
HOR/COMP input, and connect the vertical sync input to the VERT input.
Interconnection cables must be terminated with BNC connectors. Figure 2-17
show source connections for the built-in interface.

2.7 Serial Port
Connections
Serial port connections are required when the projector is to be controlled
by a computer/controller other than PHAST.
The projector’s serial ports are located on the back panel. See Figure 2-18.
Figure 2-18. Serial Port Connections
If the projector is to be controlled by a computer or controller which has an
RS-232 serial port, connect an RS-232 serial cable between the computer
and the projector serial port labeled “IN”. After the connection is made, set
the serial port baud rate as described in the Projector Setup entry in section
3.7, Utilities.
INSTALLATION & SETUP
2.16
Notes: 1) All serial connections require a 9 pin D connector at the projector end.
Refer to Appendix D for cable wiring requirements. 2) For computer/controller
control, PC software is required. 3) The RS-232 serial port labeled “OUT” is
provided for projector networking applications.
2.8 Optical
Alignment
Optical alignment is required when the throw distance changes or the projector cannot be focused using the focus controls. The projector is optically
aligned at the factory at a fixed screen size and a fixed projector-to-screen
distance. See Appendices F and G for the specific details needed for your
projector model and lens. If the throw distance has changed since the last
setup, proceed as follows:
Notes: 1) The projector must be warmed up for at least 45 minutes prior to
performing optical alignment. 2) Optical alignment is both a mechanical and
electrical adjustment. Electrical adjustments are stored in the current setup
memory. After alignment is complete, setup memories which were previously set
up (if any) must be set up again. Memory setup is explained in section 2.10. 3)
Factory alignment is performed using the internal crosshatch with a 61.8 kHz
signal applied.
It is recommended that optical alignment be performed using the projector’s
Guided Mechanical Setup tutorial. This tutorial displays step-by-step
instructions during the alignment. The instructions in this section require
use of the Guided Mechanical Setup tutorial.
To access and use the Guided
Mechanical Setup tutorial, turn on
the projector ( ) then press
at operation level. The Help menu
is displayed. Next press to select
Guided Mechanical Setup. The first
page of the guide will be displayed on
the projection screen. When using
the guide, press to display the
next page, press to display the
previous page. When complete, press
to end Help.

Also remove the black decorative foam piece at the front of the lenses
(removal is optional). Remove the large allen head driver from the tool kit
provided with the projector. The driver is used for lens alignment.
Examine the lenses and hardware as shown in Figure 2-21a (or, for the
MP-8 model, see Figure 2-21b). Each lens consists of a rear section and a
front section. The rear section sets the optical focus at the center of the
image and is secured to the lens body by a wing nut at the top rear of the
lens assembly. The front section sets the focus at the corners and is secured
to the rear section by a wing nut at the top front of the lens assembly.
