Notes
The Throw ratio for a particular
lens is fi xed, and assumes that
the image fi lls the width of the
DMD.
For images that do not fi ll the
width of the DMD, the Throw
ratio is effectively increased. To
correct for this, a Throw Ratio
Factor (TRF) is used.
The lenses available and their
part numbers are listed below:
High Brightness

Choosing a lens by calculation
For any screen size not listed above, or if you need to be more precise, then use the
calculations below.
Identify actual width of the image in pixels.
Calculate the Throw Ratio Factor: TRF = DMD width (1280)
Image width in pixels
Identify the screen width required.
Identify the throw distance required.
Throw distance calculations are based on the distance from the outer end of the
lens, which will vary from lens to lens. Once a lens has been chosen, the fi gures
can be checked using the lens extension values given on the next page.
Calculate the throw ratio required. Throw ratio = Throw distance
Screen width x TRF
Choose a lens with the required throw ratio.
Check from the lens charts or the specifi cation (see section 7. Appendix), that
the lens chosen has a suffi cient throw range.
example
An image, 1024 x 768 pixels, screen width 6.5m, throw distance 18m from the
outer end of the lens.
Throw Ratio Factor (TRF) = 1280 = 1.25
1024
Throw ratio required = 18 = 2.22
6.5 x 1.25
Choose the 1.8 - 2.4 zoom lens. •

Lens extension is measured
when the lens is focused at
infi nity, and fully extended.
At other focus settings, the
extension could be up to 10mm
less
Useful lens calculations
The following lens calculations may be useful:
Throw ratio = Throw distance
Screen width
Throw ratio factor (TRF) = DMD width in pixels = 1280
image width in pixels image
width in pixels
Therefore:
Screen width = Throw distance
Throw ratio x TRF
Throw distance = Screen width x Throw ratio x TRF
Lens extension
The throw distance calculated above is to the outer end of the lens. For each lens,
the nominal distance between the front of the projector and the outer end of the lens
(lens extension) will be as listed below.

Make sure the front lens cap is removed, before switching on the projector. Be careful not to scratch the lens surfaces. If you do accidentally touch a lens, then clean the surface using a lens paper. Locating hole Zoom drive connector Fixing screws Fitting the lens Remove the rear lens cap from the lens. Insert the lens into the lens mount with the connector to the right, taking care to line up the locating pin on the lens with the locating hole above the opening.

If the lens is to be shifted in two directions combined, the maximum range is somewhat less, as can be seen below. (zoom lens shift shown). full horizontal and vertical shift without distortion combined shift without distortion is reduced Shifting the image The normal position for the projector is at the centre of the screen. However, you can set the projector above or below the centre, or to one side, and adjust the image using the Lens shift feature to maintain a geometrically correct image. Any single adjustment outside the ranges specifi ed below may result in an unacceptable level of distortion, paricularly at the corners of the image, due to the image passing through the periphery of the lens optics. If the lens is to be shifted in two directions combined, the maximum range without distortion will be somewhat less, as can be seen in the diagrams to the right. The maximum range available with no distortion is dependent on which lens is used. The tables below show the maximum range for images that fi ll the DMD.

Rev B 02/2007 Page 2.15 Digital Projection TITAN HD-500, HD-250 User Manual 2. Installation Mounting the projector The projector is designed to be used on a fl at surface, but the optional rigging frame will allow it to be suspended from a lighting truss or rigging. The four adjustable feet under the chassis allow the projector to be lowered onto a fl at surface without any danger of hands being trapped between the bottom frame and the surface. Chassis adjustment If the projector is to be operated from a fl at surface such as a projector table, then adjustment of projector level should be made by turning the four feet under the chassis. Fitting the optional rigging frame The rigging frame should be secured to the projector using the twelve screws supplied, as shown in the pictures below. Four screws secure each of the threee adjuster brackets to its corner post. Fit the screws to the round holes fi rst, then fi t the screws to the oval holes. Before suspending the projector, make sure that all the frame adjusters are set roughly midway. • • Notes BEFORE INSTALLING THE PROJECTOR, READ ALL THE WARNINGS BELOW AND ALL THOSE IN IMPORTANT INFORMATION AT THE FRONT OF THIS MANUAL. The projector weighs approximately 27 kg (50 lbs). Use safe handling techniques when lifting the projector. Make sure that the surface, ceiling or rigging that is to support the projector is capable of supporting the combined weight of the projector and lens (see specifi cation for weights). Backup safety chains or wires should always be used. Do not tilt the projector more than ±12° from side to side when in use, as this may cause serious lamp failure, damage the lamp module and cause extra cost on replacement. The projector my be tilted forwards and backwards as necessary. ±12° 360° Fixing screws Adjustable foot
Page 2.16 Rev B 02/2007 2. Installation Digital Projection TITAN HD-500, HD-250 User Manual Adjusting the rigging frame Coarse adjustment of projector level should be made by adjusting the length of the supporting wires or chains, or by adjusting the position of the truss or rigging. Once the initial coarse adjustment has been made, fi ne adjustment can be made by turning the frame adjusters on the rigging frame: The single vertical adjuster at the front left corner is used to raise or lower the front of the projector (pitch adjustment). The two vertical adjusters at the rear are used to rotate the projector around the lens axis (roll adjustment). The horizontal adjuster at the rear right corner (viewed from the front) is used to rotate the projector around its vertical axis (yaw adjustment). • • • Notes BEFORE INSTALLING THE PROJECTOR, READ ALL THE WARNINGS BELOW AND ALL THOSE IN IMPORTANT INFORMATION AT THE FRONT OF THIS MANUAL.

Rev B 02/2007 Page 2.17 Digital Projection TITAN HD-500, HD-250 User Manual 2. Installation Notes When stacking projectors, the stack MUST be vertical, to ensure that the stresses are distributed to all frame couplings. Make sure that the surface, ceiling or rigging that is to support the projector is capable of supporting the combined weight of all the projectors and lenses (see specifi cation for weights). Do not place heavy objects on top of the projector chassis. Only the chassis corners and the rigging frame are capable of withstanding the weight of another projector. Do not try to stack more than 3 projectors. Separate backup safety chains or wires should always be used for each projector. Stacking projectors The rigging frame is capable of supporting the weight of up to two other projectors, using the built-in frame couplings. The projectors can be stacked on top of each other, or suspended below each other. Carefully lower each projector down onto the top of the others, making sure that all four frame couplings engage fully. Fit a locking pin into each coupling. A ball in the end of the pin prevents the pin from falling out – to insert or remove a locking pin, press the button on the t-bar to release the ball. Align the images from the projectors, following the instructions in section 3. Getting started, Adjusting the lens and Adjusting the projected image. • • • Locking pin Frame couplings

Overview, Using the control keys, and Using the menus. Input 4. is not used on this projector. For more information about pin connections and control codes see section 7. Appendix. For more information on input modes see section 4. Overview. Connecting the projector Signal Inputs The following inputs are available: EDID handshaking on the DVI and RGB2 inputs If you are using a computer DVI card or other source that obeys the EDID handshaking protocol, then the card or source will automatically confi gure itself to suit the projector. If not, then you should refer to the documentation supplied with the source to manually set the resolution to 1280 x 720 or the nearest suitable setting. Switch off the source, connect to the projector, then switch the source back on again. 5. Composite Video 6. S-Video 7. Component 1. RGB12. RGB2 3. DVI Input connection panelControl connection panel
