DCR-J1
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.
ABOUT GEOMETRIC DISTORTION. Anamorphic vertical
compression lenses create a slight “barrel” shaped curvature
especially at the edges of the image. The amount of this distortion
decreases as the projection distance is increased for a given
screen size. See the Image Geometry estimator in the Lens Selector
at for approximate distortion to expect. Masking www.panamorph.com
the edges of the image by the screen border makes this distortion
much less noticeable especially for dramatic content.
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.

IMPORTANT THEATER GUIDANCE
1. Projection screen should be , in the aspect ratio and with a flat 2.4:1
minimum 1.5″ border.
2. Projector should be horizontally centered on the screen +/- 3 inches
with minimal horizontal lens shift. Projector should vertical position
ideally be between -5” and +12” from the top of the screen for best
performance. Beyond these limits may prevent the beam from passing
through the lens at low throw ratios.
3. (throw distance divided by screen viewable width) Throw ratio
should be .at least 1.4:1

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 (do not over tighten). As desired you may want to adjust the
projector pixel alignment (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 However, , Anamorphic D. 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.

INSTALL THE DCR LENS RETAINER. Use projector lens shift
to center the projector lens in its opening. 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. Adjust the projector roll, tilt
and/or yaw so the projector test pattern lines are square to the
screen edges. Now, show a 2.4:1 movie and set the JVC
anamorphic menu setting to . Adjust the Anamorphic C
projector zoom and vertical lens shift so the movie pattern is centered
on the screen. Make sure the projector lens is clean and as dust free
as possible.
