INSTALLATION GUIDE
(Phillips #2 screwdriver required)
Anamorphic Lens System
CEILING OR SHELF MOUNTING. Regardless of the projector
orientation the DCR retainer should be installed with the prongs closer
to the ceiling so the Panamorph logo is upright after installation.
LIMITED WARRANTY. Panamorph, Inc. warrants this product against
any change in performance or functionality for a period of twenty-four
months from our ship date. During this period, a unit may be repaired
or replaced, at the discretion of Panamorph, Inc., by returning it in its
original packaging with a copy of your receipt. This warranty does not
cover damage resultant from lack of prudent care, accident or misuse
(including use with other products in ways not intended); any cosmetic
damage not reported within 15 days of purchase; or any performance
change caused by the environment in which it is used. All damages are
limited to the cost of the product.
ABOUT GEOMETRIC DISTORTION. Anamorphic vertical
compression lenses such as the DCR naturally create a slight “barrel”
shaped curvature especially at the edges of the image. The amount of
this curvature is greatest at the minimum recommended projector
throw ratio of 1.4:1 and decreases as the projector is located
farther back from a given screen size. However, most content is
actually created with more internal geometric distortion than that from
an anamorphic lens. Once residual edge distortion is masked by the
edge of the screen the effect becomes quite unnoticeable.
CLEANING. Small amounts of dust and wipe marks are very
noticeable on lens surfaces with a high brightness projection beam but
typically will not impact the image as much as damage from excessive
cleaning in pursuit of a "perfect" optical surface. Occasionally blowing
off the lens surfaces with clean air is the best way to keep long term
performance. If there is any excessive residue or build-up then it is
recommended that you 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 you to quickly see if the cleaning
process is causing any damage.
For use only with the following JVC projector models:
DLA-RS1000 and DLA-NX5 (International: DLA-N5)
DLA-RS2000 and DLA-NX7 (International: DLA-N7)
1. Projection screen should be flat, in the 2.4:1 aspect ratio and with a
minimum 1.5″ border.
IMPORTANT THEATER GUIDANCE
2. Projector should be horizontally centered on the screen +/- 3 inches
with minimal horizontal lens shift.
3. Throw ratio (throw distance divided by screen viewable width)
should be at least 1.4:1.
4. Projector vertical position should ideally be close to the top of the
screen with limits of up to 10% of screen height below to 30% of
screen height above for best performance. Beyond these limits may
prevent the beam from passing through the lens at low throw ratios.

INSTALL THE DCR LENS RETAINER. Remove the two front
Phillips assembly screws from the lens/mount assembly and
remove the rear retainer (it comes loosely assembled).
Squeeze the retainer with locking tab disengaged to fit into the
projector lens opening and then relax it so that it nests into the
inner rim of the opening with the prongs level and closest to the ceiling.
Once nested, engage the locking tab to prevent release.
PREPARE THE PROJECTOR. Make sure the projector lens is
horizontally centered in its opening (ie little or no horizontal lens
shift). Adjust the projector roll, tilt and/or yaw so the projector
test pattern lines are square to the screen edges and the test
pattern is centered on the screen. Then ...
Show a 2.4:1 movie. Set the JVC anamorphic menu setting to
Anamorphic C. Make sure the projector lens is clean and as dust free
as possible.
INSTALL THE DCR LENS. After removing the rear DCR lens
cover, install the DCR lens/mount assembly over the retainer
prongs; remove the front protective film; rotate the assembly so
that any visible edges of the movie appear the same on the left
and right; then insert and tighten the two assembly screws to secure
(do not over tighten).
ADJUST THE LENS TILT AND PROJECTOR SHIFT. Adjust
the projector lens zoom to fill the width of the screen with the
movie. Tilt the DCR lens in its mount and adjust the projector
vertical lens shift to make sure the beam is getting through the
DCR lens to fill the screen. There is only a slight variation in vertical
image height with this adjustment but experimentation may lead to the
best fit. Lock the DCR lens tilt by tightening the single Phillips tilt lock
screw. As desired you may want to adjust any pixel alignment in the
projector (see JVC projector instruction manual).
DECIDE HOW TO WATCH 16:9 CONTENT. The “classic”
mode to watch 16:9 content is to set the projector anamorphic
mode to Anamorphic D. However, Anamorphic C,
Anamorphic Off or Zoom will better fill the full cinema format
screen with 16:9 content with various tradeoffs worth exploring. Note
that menus are always created in 16:9 so some type of switch from
Anamorphic C will be necessary to show complete menu content.
