C3X LINK

For rear projection the screen must be translucent.
For front projection, we recommend the use of screens with
low gain specifications.
Preferably use “unitary gain” screens; directive screens with
a high gain can be effectively used only for small groups of
spectators central to the screen.
Avoid light shining directly on the screen during projection as
this will reduce contrast and black level detail on the projected
image.
Furniture and other objects with reflecting surfaces, as well as
light coloured walls should be avoided, as they are likely to
interfere with the screen’s characteristics.
CONNECTING THE VIDEO SOURCES
Connect the cables from the video sources, the serial cable
from an external control unit and the fibre optic cables for hoo-
king up with the Projector to the rear panel of the DigiOptic™
Image Processor.
To obtain the best performance from the C3X-LINK system,
connect the various signal sources using good quality cables
designed for video applications.
Ensure that:
• the cables are routed in such a way that they do not present
an obstruction to people moving around the room;
• the connectors are inserted carefully to avoid damaging
the pins;
• the cables are not twisted or crushed;
• when disconnecting the cables the connectors are not vio-
lently pulled out of the connectors on the various units.
Video sources (television receivers, VCRs, DVD players, etc.)
often feature several outputs. To obtain the best performance
from your system, carefully choose which output to use. Gene-
rally, the type of signal offering the best picture quality is HDMI™,
followed by DVI-D, RGB, Components, S-Video and Composite
Video, in that order.
However, the C3X-LINK system is equipped with an excellent
Video Decoder and Deinterlacer and therefore even inferior
quality signals will produce high quality results.
Table 1 shows the types of signals usually available for the most
common types of video sources and the corresponding input
connectors to use on the DigiOptic™ Image Processor.

These inputs should be connected to a Composite Video signal
(CVBS) by means of a cable with an RCA connector.
The source connector is usually yellow and is frequently labelled
VIDEO.
Although other types of signals are preferable (since they al-
low better picture quality), this is still the most common type
of output, and nearly all television receivers, video-recorders,
DVD players, video cameras, etc., are equipped with CVBS
outputs.
S-VIDEO

These inputs should be connected to an S-Video signal by
means of a cable with a mini-DIN type connector.
The corresponding output on the source can be identified by
the wording S-VIDEO or Y/C.
Almost as widespread as Composite Video, S-VIDEO is prefera-
ble because it offers a clearer and sharper picture.
COMPONENT / RGBS

These inputs are composed of three sets of 5 RCA connectors
RCA (5,6,7) and one set of 5 BNC connectors (8).
Each set of connectors is suitable for RGB and Component
signals.
RGB signals can have the following synchronisations: compo-
site sync on the green signal (RGsB), H+V Composite Sync, or
separate H/V Sync.
Connect the R, G, B outputs of the source to the respective R,
G, B inputs of the DigiOptic™ Image Processor (taking care not
to invert the positions) and any synchronisation signals to the
HV input or the H and V inputs. When connecting the three sets
of RCA connectors use the colours as a guide: connector R is
red, G is green, B is blue, H/HV is white and V is black.
