INTRODUCTION
Thank ou for purchasing the Optoma BX-AL133B lens s stem – the world’s leading model
anamorphic lens s stem designed to dramaticall enhance toda ’s high performance 16:9
projectors when showing the true widescreen aspect ratio of most major motion pictures.
The BX-AL133B lens s stem includes the UH480 Lens and ATH1 automated transport to
provide the optimum performance when viewing all wide screen content. The ATH1 transport
can be mounted to our ceiling, to an improvised ceiling structure, or to the pre-engineered
AKPro Attachment Kit. However, due to the ver simple Plug-and-Pla procedure the offer,
use of these kits will be the focus of this installation guide.
UH480 BASIC PROJECTION PARAMETERS
Throw Distan e (distance from projector lens to screen)
This distance should be between 12 and 25 feet (3.6M and 7.6M) with the
standard UH480 lens with an ideal range of 14.5 to 17.5 feet (4.4M to 5.3M) for the
highest pixel level clarit , especiall for computer graphics applications at 1080
resolution. If our projection s stem involves a significantl higher throw distance then
we recommend purchasing an optional correction element (see www.panamorph.com) if
ou need graphic level performance.
Throw Ratio (ratio of throw distance to 16:9 native image width)
This ratio primaril impacts image distortion. To minimize the amount that the
image edges bow inward a throw ratio of at least 1.6 is recommended.
If larger distortion is acceptable, the large aperture of the UH480 will generall
work with a throw ratio as low as 1.3 as long as the beam passes through the lens
unobstructed. Due to the large distortion and also the increased non-uniformit of image
brightness (hot spotting) at ver low throw ratios ou ma wish to consider a curved
screen in such cases to help compensate for these artifacts.
Image/Lens Shift
Horizontal lens/image shift other than fine adjustment is not recommended due to
ke stoning that can be introduced b the UH480. Vertical lens shift does not impact the
use of the UH480. However, note that with vertical lens shift the UH480 should be tilted
to face the approximate center of the screen to make an residual pincushion distortion
s mmetric at the top and bottom of the image.
A NOTE ON YOUR SCREEN FORMAT
The BX-AL133B s stem works ver well with a 2.35:1 aspect ratio screen. However, if ou are
considering a new screen we actuall recommend an aspect ratio of 2.40:1 for the best all
around fit. The 2.35:1 aspect ratio is somewhat of a film industr designation for man aspect
ratios around 2.35:1 and ma include man titles up to 2.40:1 and occasionall higher.
Consequentl , b following these installation instructions we will help ou optimize our constant
height imaging performance for all three primar aspect ratios of 16:9, 1.85:1 and the general
range of 2.35:1-2.40:1.

USING the AKPro ATTACHMENT KIT
The AKPro includes a high performance, rigid, solid steel plate specificall designed to attach to
a properl installed model RPA ceiling mount head made b Chief Manufacturing, which ma
then be further installed to the ceiling using a variet of standard Chief components. These
components are not included in the kit but are available from most qualified home theater
installers. The RPA and asso iated hardware must be installed to eiling stru tural
members to support at least 250 pounds and must be extremely rigid. Any play in the
RPA mount will result in a ro king of the AKPro assembly as the lens moves in and out
of the proje tor beam and represents a danger to equipment and personnel.
The AKPro Attachment kit ma also be used with a projector mount from another manufacturer
apart from Chief. If ou wish to use a different projector mount the lens s stem is stabilized b
using two chains extending from the front area of the plate to ceiling attachment points. You
ma skip ahead to Page 6 and the section titled: “Alternate Atta hment Plate Method”
IMPORTANT CEILING MOUNT LOCATION CONSIDERATIONS
For optimum imaging results consult our projector’s instructions for the ceiling mount location
to place the projector’s lens in the horizontal center (ie left to right) of our projection screen
(even if our projector has a horizontal lens/image shift capabilit ). In addition, make sure ou
are not at the limits of our projector’s zoom capabilit so that ou have some range for image
adjustments.
The AKPro attachment plate is designed so that the projector and other attached components
form an average center of mass (gravit ) approximatel located at the center of the ceiling
mount pipe. Therefore, the ideal eiling mount lo ation will be shifted by the AKPro 2”
(50mm) toward the left side of the s reen from the ceiling mount location indicated b our
projector’s instructions.
If our projector ceiling mount is alread installed and ou do not wish to move it (or similarl
move the screen in the opposite direction) due to a shift b the AKPro s stem, then ou can
make fine horizontal shift adjustments to our projector (if available) combined with turning the
projector (onl as necessar ) during final setup to compensate for the shift. Some small amount
of image distortion (horizontal ke stoning) ma result but in most cases this will not be
noticeable since the image edges will t picall be masked b the screen borders.
WARNING!
Use extreme aution and appropriate hardware when installing heavy obje ts to a
eiling. Periodi ally he k all fasteners and onne tion hardware to be sure they are
not oming loose. Improper installation may lead to an in reased risk of your
equipment be oming unstable and possibly injuring someone.

CONNECTING THE AKPro ATTACHMENT PLATE
(Chief RPA mount and Phillips screwdrivers required)
1. Position the projector bottom-up. Consult the Attachment Plate Diagram for plate orientation,
hole positions and required screws and spacers for our projector model. Insert and tighten
each screw through an appropriate silver washer and lock washer, the designated holes in the
Attachment Plate, then through an required spacers and finall into the projector ceiling mount
holes.
2. Using the included gold hex ke , install the six 7/8” socket head screws each through a 3/8”
aluminum spacer and into the six threaded holes from the ceiling side of the attachment plate.
Thread onl enough to extend the screw to the bottom of the plate.
3. Insure that the RPA mount head is secure (see instructions included with the RPA mount)
and oriented properl relative to the 7/8” socket head screw heads so that the mounted
projector will face the screen. Use two people to lift and position the projection assembl so that
the heads of each of the 7/8” socket head screws rest within the matching final location of the
RPA mount head. At this point the silver 3/8” spacers should be between the Attachment Plate
and the RPA mount head. The projection assembl ma be lowered to allow the 7/8” screw
heads to rest on the RPA mount. However, a first person should continue to guide the
projection assembl while and a second person uses the gold assembl wrench to tighten the
7/8” screws. When tightening these screws, do so in a pattern of incrementall driving each
screw a little more into the attachment plate so that at an time the projection assembl is
resting on as man screw heads as possible until all are tightened.
If the lens must be removed for an length of time it is recommended that a similar weight be
suspended from the front of the attachment kit to balance the weight of the projector. This will
minimize unusual stresses on the ceiling mount s stem.

ALTERNATE ATTACHMENT PLATE METHOD
(Phillips screwdrivers, pliers, scissors and appropriate ceiling hooks required)
1. Install the Plate Hook Assemblies in the two “H”
holes of the Attachment Plate (see diagram) with the
hook ends on the ceiling side as shown above. Use
pliers to bend the closed hooks apart just enough to
install a Chain End at a later time.
2. Position the projector bottom-up. Consult the
Attachment Plate Diagram for plate orientation, hole
positions and required screws and spacers for our
projector model. Insert and tighten the required screws through the ceiling mount adapter (not
included), then through the designated holes of the Attachment Plate, and then through an
required spacers and finall into the projector ceiling mount holes
3. Securel connect the projector assembl to the ceiling mount and then adjust the projector
and ceiling mount to center the projector's image in the horizontal center of our screen.
4. Install ceiling hooks (not supplied) into the ceiling directl above the Plate Hooks. The
eiling hooks should be small enough to a ept a Chain End but strong enough when
installed to ea h support 40 pounds or more.
5. Attach a Chain End to the Chain and then connect to one of the ceiling hooks. Cut the Chain
and assemble to another Chain End for a best fit to the corresponding Plate Hook and attach.
Repeat for the other set of hooks.
6. Adjust and tighten the nuts on the Plate Hook Assemblies to make the Chains tight but
without raising the front of the Attachment Plate. You ma wish to turn the projector on to
ensure the image remains properl oriented to the screen during this step. At this point proceed
to the appropriate lens/transport mounting step.

MOUNTING THE ATH1 TRANSPORT
1. DO NOT CONNECT POWER TO THE TRANSPORT AT THIS TIME.
2. Position the flat side of the
motorized transport against the bottom
side of the Attachment Plate so that the
transport logo is toward the screen and
the center “M” hole in the Attachment
Plate is aligned with the front recessed
transport hole. Insert the #10-32 pivot
screw up through the transport and
Attachment Plate and loosel complete
the assembl with the corresponding
washer, lock washer and nut. Now
loosel insert the four small 3/8” screws
through the four remaining “M” slots through the top of the Attachment Plate and down into the
transport.
3. Refer to the ATH1 user manual (included with ATH1) for additional instructions to install
the lens at this time, but do not forget to complete the “Final Adjustments” step below.
FINAL ADJUSTMENTS (ALL INSTALLATIONS)
1. Turn the projector on with the UH480 Lens out of the projector beam. Set the horizontal
lens shift to neutral (if a feature of our projector) and then adjust the ceiling mount so that the
16:9 image is in the exact center of and square to the screen, with a similar amount of image
slightl over the top and bottom screen borders. If the projector lens is not in the exact
horizontal center of the screen ou ma need to use a little horizontal lens shift for this purpose.
2. Bring the UH480 Lens into the beam. Adjust the vertical position and tilt of the Lens so
that the projector beam is passing through the center of the Lens and so an residual
pincushion distortion is about the same at the top and bottom of the image. This will t picall
result in the UH480 Lens being below the center of the projector lens and tilted slightl
downward. Tighten the knobs.
3. Adjust the rotation of the ATH1 transport so that the left and right sides of the image are
an equal distance from their respective screen borders. Now tighten the Pivot Screw (M380)
and also the four remaining screws holding the transport to the Attachment Plate.
4. For optimum multiple aspect ratio performance, adjust the projector’s zoom so that a
1.85:1 aspect ratio movie (Lens “out”) is just masked b the top and bottom of the screen
border. This wa 1.85:1, 16:9 and 2.35-2.4:1 aspect ratio movies should all be presented to fill
the screen at a constant height.

CLEANING
In most applications lenses do not need ver much cleaning – a bit of dust will not impact image
clarit . However, in toda ’s high performance home cinemas with ver dark rooms a small
build-up of dust or other foreign matter on our projector lens or our Panamorph lens can
produce a measurable reduction in contrast. The most effective cleaning approach is to simpl
blow off an dust. If there is an residue or build-up then it is recommended that ou clean the
optics with professional lens cleaning supplies such as from a camera store while the lens is in
front of the lit beam of the projector. This will allow ou to quickl see both the results of
cleaning and also if ou are causing an damage.
