SWITCHING OFF AND RETURNING TO STAND-BY
By remote control: press  .
By keyboard: press key  .
When switching off, the projector goes in to stand-by  memo-
rising the input selection at the time of switch-off.
The fans will continue to work until the lamp has cooled down  
(red and green LEDs flashing) and will stop automatically after 
this period. 
  
6   CONNECTIONS
To obtain the best performance from your projector, we recom-
mend  the  use  of  good  quality  “ video  cables”  to  the  various 
signal sources (75 ohm Impedance).
Poor quality cables will cause inferior picture performance. 
For  optimum  connectivity  we  recommend  you  follow  these 
simple steps:
- With exception of coaxial RcA/Phono type connectors,  
always  double-check  that  the  plug  is  inserted  the  correct 
way round to avoid damaging the plugs or the sockets on 
the projector (Fig. 15)
-    Remove cables by the plug and do not pull on the cable 
itself.  
- Avoid tangled cables.

definition video).
Progressive  signals  usually  provide  better  quality  than  interla-
ced  signals,  but  if  the  source  features  both  progressive  and 
deinterlaced  signal  outputs  it  is  good  practice  to  compare 
the  quality  of  the  pictures  reproduced  by  the C3X  in  the  two 
cases: deinterlacing performed by the C3X (thanks to Faroudja 
DCDi™ technology) is often more effective than that performed 
at the source.
GRAPHICS RGB
This input should be connected to an RGB-type video or graphic 
signal using a cable with a DB15HD type connector.
The  signal  source  device  (typically  a  personal  computer  or 
game console) must be able to provide separate H/V synchro-
nisation or composite H+V.
The video or graphic signals that can be connected to this input 
can have horizontal scan frequencies (H-sync) of between 32 
and  80  kHz  and  a  vertical  frequency  (V-sync)  of  between  48 
and 100 Hz. Image resolution can var y between 640x480 and 
1600x1200 pixels (VGA, SVGA, XGA, SXGA, UXGA).
HDMI™
The HDMI™ (High Definition Multimedia Interface) integrates an 
uncompressed high definition video signal with a multichannel 
audio signal and allows the exchange of control data between 
the video source and the C3X.
The HDMI™ input provides connection to video sources that use 
the HDCP (High-Bandwidth Digital Content Protection) protocol 
to protect contents. 
Once  the  video  source  has  been  connected  to  the  HDMI™ 
input,  internal  processing  by  the C3X  separates  the  video 
information  from  the  audio  information.  Audio  information  is 
then made available via an optical digital output with a female 
TOSLINK connector in accordance with the S/PDIF standard.
COMPOSITE VIDEO
This input should be connected to a Composite Video signal 
(CVBS) by means of a cable with an RCA connector.
The connector on the source is usually yellow and is frequently 
labelled VIDEO.
Although other types of signals are preferable (since they allow 
better picture quality), Composite Video signal is still ver y com-
mon, and nearly all television receivers, video-recorders, DVD 
players, camcorders, etc., are equipped with it.
S-VIDEO 
This input should be connected to an S-Video signal by means 
of a cable with a 4-pin mini-DIN type connector.
The corresponding output on the source can be identified by 
the labels S-VIDEO or Y/C.
Almost as widespread as Composite Video, S-VIDEO is prefera-
ble because it offers a clearer and sharper picture.
RGB / YPrPb 
These inputs are composed of one set of 4 RCA connectors.
Each  set  of  connectors  is  suitable  for  RGB  and  Component 
signals.
RGB  signals  can  have  the  following  sync  signals:  composite 
sync on the green signal (RGsB), H+V Composite Sync.
Connect the R, G, B outputs of the source to the respective R, G, 
B inputs of the C3X (paying attention not to invert the positions) 
and synch signals to the HV input.
When  connecting  the  three  sets  of  RCA  connectors  use  the 
colours  as  a  guide:  connector  R  is  red,  G  is  green,  B  is  blue, 
HV is white.
By using a suitable SCART to RCA (or BNC) connector adapter 
cable,  an  RGB  video  signal  from  a  source  equipped  with  an 
SCART connector can be connected to this input.
- Component signals should be connected to inputs Y, Cr and 
Cb, taking care to observe the correspondence with the outputs 
on the source.  The connector colours can also be of help, as 
shown in the table.
The  video  signals  that  can  be  connected  to  this  input  can 
have horizontal scanning frequencies of 15 kHz (standard video 
resolution), 32 kHz, or higher (progressive scanning video, high

12Volt
The projector is equipped with two outputs (Voltage: 1  Vdc) for 
motorised projection screen and screen masking systems. These 
1V outputs should be connected to the appropriate screen 
interface provided by the screen manufacturer (Fig. 17).
The  +1V  output  is  activated  when  the  projector  is  switched 
on (green LED on) and is de-activated when the projector is in 
stand-by mode (red LED on).
The output   can be used to control a screen masking system; 
its output can be set with the Screen control adjustment in the  
Aspect menu. This output allows reduction in the area of a 16:9 
screen, into a 4:3 format, by activating a screen masking system 
(refer to screen manufacturer for further information).

Insert the batteries, taking care to match the polarity, as indi-
cated in the batter y recess of the remote (Fig. 3).
c hange  the  batteries  in  the  remote  control  if  experiencing 
difficulty in sending commands to the projector.
If  the  remote  control  is  not  to  be  used  for  a  long  period  of 
time remove the batteries. Replace all batteries at the same 
time;  do  not  replace  one  new  batter y  with  a  used  batter y.  If 
the batteries have leaked, carefully wipe the case clean and 
replace with new batteries.
The  remote  control  sends  commands  to  the  projector  via 
infrared signals.
It  is  possible  to  control  the  projector  by  pointing  the  remote 
control at the screen; the sensor at the front of the projector will 
pick up the reflected infrared commands. (Fig. 19).

INPUTS
The input selection menu (Inputs) is called by pressing 0 on the 
remote control and, when no other menu is displayed, using 
the ▲ and ▼ keys on the keypad. To select an input, scroll the 
list with the ▲ and ▼ keys until the desired input is highlighted, 
then press ▶.
Display of the input selection menu is terminated 
by pressing the ESc key, or when the time allowed for displaying 
the on-screen menu has lapsed (set in the Set-up Menu).
Input 5 can accept RGB and YPrPb signals with a scan frequen-
cy up to 3Khz.
Inputs can receive RGB and YPrPb signals, at 15 kHz, 3 kHz or 
higher. The association between the input and the type of signal 
(RGB or YPrPb) is made from the pull-down menu that appears 
on the right of the < symbol after pressing the ◀ key (Fig. 0).
In the pull-down menu it is also possible to choose the horizontal 
frequency or use the AutoSync feature; in this case the system 
detect the horizontal frequency signal (15KHz, 3KHz or higher) 
automatically.
Input is capable of receiving YPrPb or RGB signals coming from 
DVI-D sources.
The selection should be made from the drop menu following 
the indications described above.
After  selecting  the  source  signal  (by  means  of  the ▲  and ▼ 
keys),  press MENU+/MENU-  to  confirm  and  close  the  pull-down

PICTURE
This menu features the adjustments related to picture quality. 
Adjustments  that  are  not  available  for  a  given  input  do  not  
appear on the menu. Table 1 summarises the adjustments avai-
lable for each input. For a complete overview of the on-screen 
menus,  consult  the ON S c REEN  MENU  LAYOUT  in  the A DDITIONAL 
INFORMATION section. 
 
RIGHTNESS
Use  this  control  to  adjust  the  image’s  black  level  without  
affecting white areas. Increasing the value will give more detail 
in darker parts of the picture. For correct adjustment it may prove 
useful to display the signal relative to the grey scale within which 
the  black  level  and  the  level  immediately  above  it  must  be 
separately identifiable. Alternatively use a scene composed of 
black objects alongside other dark coloured objects.
CONTRAST
Use this control to adjust the image’s black level without affec-
ting white areas.
To ensure correct adjustment, it may prove useful to display the 
signal relative to the grey scale, within which the white level and 
the level immediately below it must be separately identifiable. 
Alternatively  use  a  scene  composed  of  well-lit  white  objects 
surrounded by light coloured objects with lower level lighting.

COLOR
This  control  (also  called  Saturation)  increases  or  decreases  
the  picture  colour  intensity.  When  set  to  zero,  colour  images  
will  be  shown  in  black  and  white.  Increasing  the  value,  tr y  to  
find the point at which the colours look natural: suitable referen-
ces include skin tones and grass in landscape shots.
TINT
controls  the  purity  of  the  colours.  Basically  determines  the  
red-green ratio of the picture. 
Reducing  the  value  will  boost  the  red  contents  of  the  pictu-
re,  increasing  the  value  will  boost  the  green  tones.  For  this 
adjustment use skin tones or a test pattern image with colour  
bars as a reference. 
SHARPNESS
Use  this  adjustment  to  increase  and  decrease  the  level  of  
picture detail. 
When  the  sharpness  value  is  reduced  the  image  details  
appear  less  pronounced,  while  increasing  the  value  raises  
image definition, making the outline of objects sharper. 
Note that an excessively high value may result in a ‘noisy ’ picture 
and the edges of objects may be unnaturally defined.
SHARPNESS MODE
This  allows  you  to  select  the  type  of  processing  associated  
with sharpness adjustment. In the case of a progressive or in-
terlaced video signal VIDEO mode is advisable; with Pc graphic 
signals use GRAPHIc MODE.
FILTER
This  allows  you  to  select  the  mode  in  which  the  input  signal  
is processed. Selecting the most appropriate value for a given 
input signal ensures the best horizontal and vertical definition 
and makes the picture sharper.

CINEMA MODE
In AUTO the  deinterlacer  recognises  if  the  video  signal  source  
is  a  movie  film  (obtained  from  a  Telecine  device  with  3:  or 
: pull-down) and applies a deinterlace algorithm optimised 
for this type of signal.
If the video signal source is not identified as a film, or if you select 
NO the deinterlacer applies a Motion compensated algorithm 
optimised for video camera signals.
VIDEO TYPE
Activates a filter to improve stability of pictures from video re-
corders or DVD players. To toggle between NORMAL, VcR1 mode 
and VcR mode press  on the remote control. 
NOISE  REDUCTION
This  adjustments  allows  to  choose  the  filter  value  for  noise 
reduction purposes.
As  soon  as  this  option  is  selected  on  the  menu,  the  image  is 
divided in two parts.
In the left side the image is not altered by the filter, in the right 
part the filter is activated.
This allows you to compare the effect of the filter.
It is possible to deactivated the filter (NOT AcTIVE), to use the au-
tomatic  adjustments  (AUTO)  or  to  manually  select  (MANUAL)  the 
value suitable for the image with the VALUE adjustment.
In  case  of  using  the VALUE  adjustement,  it  is  enoght  to  select 
to  cursor  below  and  set  the  value  with  the ◀  e ▶  keys  of  the 
remote control.
Associated to the NOISE REDUcTION there is the possibility to use the 
specific function (FLESH TONE  cORREcTION) to make skin tone more 
natural. Often the use of noise reduction filter slightly degrades 
the image in those areas where skin tones are visible. With the 
use of this function it is possible to maintain an excellent image 
quality throughout the entire projected image. 
IMAGE
This  menu  features  adjustments  relating  to  picture  position, 
aspect ratio, etc.
ASPECT
This  adjustment  allows  you  to  change  the  dimensions  and 
aspect  ratio  (relationship  between  width  and  height)  of  the 
displayed image. There are five preset aspects available and 
three personalised aspects (with user-settable parameters). You 
can  select  a  different  aspect  for  each  source:  the  selected 
aspect  ratio  will  be  automatically  called  the  next  time  the 
relative source is called.
You  can  also  select  the  required  aspect  ratio  by  repeatedly 
pressing the  key, or by pressing  and a numerical key 
(1...8).
The following aspects are available.
NORMAL:  projects  the  image  occupying  the  full  height  of  the 
screen  while  maintaining  the  aspect  ratio  of  the  input  signal. 
When the input signal aspect ratio is 4:3 black vertical bands 
are displayed on the right and left of the picture.
ANAMORPHIc: allows a 16:9 picture to be displayed correctly.
LETTERBOX: serves to display 4:3 letterbox image (with source si-
gnal having black bands above and below the picture) so that 
it fills the 16:9 screen and maintains the correct aspect ratio. 
PANORAMI c: this aspect stretches the 4:3 image, slightly cropping 
the upper and lower parts.
Panoramic  is  ideal  for  displaying  a  4:3  image  on  the  16:9 
screen of the Display.
 
PIXEL TO PIXEL: this aspect displays the image as it is input without 
adapting it to the screen. 
The image is projected in the centre of the screen and if its ho-
rizontal and/or vertical dimensions are smaller than the display,

ScREEN cONTROL
If an appropriate screen-masking interface is connected to the 
1V output socket it is possible, for each aspect chosen, to re-
frame the screen to a variety of aspect ratios and screen sizes 
(please refer to the screen manufacturer ’s manual). 
COLOR TEMPERATURE
The color temperature adjustment is made by positioning  the 
white point inside cIE cromaticity diagram.
The systems allows to choose from 36 predefined white points  
inside the neutral color area (Fig.3).
The correlated color temperature varies  along horizontal lines,  
low  temperatures  are  present  in  the  right  side  (where  the  red 
component is increased),  in the left side of the diagram you 
can find high temperature values ( in which blue component  
is  higher).  The  points  along  the  lower  horiziontal  line  (Fig.4) 
represent colors that  belong to the black body curve.
Along vertical lines the color temperature is constant but is  dif-
ferent  from black body curve, which mean if you select point 
from  the  high  part  of  the    diagram  you  increase  the  green 
componet,  while  low  part  of  diagram  cause  an  increase  of 
purple component.

GAMMA CORRECTION
Determines the system’s response to the grey scale, empha-
sising or attenuating the different grades of brightness (blacks, 
dark, medium, light grey, whites) in the projected image. 
The  projector  is  equipped  with  several  gamma  functions,  al-
lowing  the  best  display  of  any  image  in  relation  to  the  video 
source type, ambient light conditions, and the personal pref-
erences of the viewer.
The  system  provides  4  groups  of  gamma  curves:  Standard 
(ST),  Enhanced  SIM  (EN),  Graphics  (GR),  and  Personal.  The 
Standard  curve  is  suitable  for  generic  use:  this  curve  is  well 
adapted  to  displaying  images  from  video  cameras,  dig-
ital  cameras,  and  films  or  photos  from  personal  computers. 
The  Enhanced  group  is  suitable  for  viewing  movie  films.  The 
Graphics  group  is  suitable  for  displaying  simple  graphic  im-
ages  (desktop  Pc , cAD,  Pc  presentations,…).  The  Personal 
setting allows the gamma curve to be defined parametrically. 
The user can select the coefficient that determines the shape 
of the curve.  coefficient values between 1.5 and  . serve to 
emphasise  details  in  darker  parts  of  the  picture  although  the 
global  perception  of  contrast  is  reduced.  Values  higher  than 
. increase the global perception of contrast while attenuat-
ing the visibility of details in darker areas of the picture. With the 
most  common  video  sources  a  parameter  value  of  .  will 
give high quality pictures with the right amount of contrast. 
POSITION
Use this adjustment to position the image vertically and horizon-
tally. Determines the aspect ratio of the projected image.
These parameters do not normally require adjustment because 
the system checks the input signal and automatically sets the 
most suitable values. 
However, if the image is not perfectly centralised it may prove 
useful to request the system to repeat the input signal analysis

and image positioning, calling the automatic control procedure 
from the AUTO button on the remote control or keypad. When this 
procedure is called it is helpful to have a white or light coloured 
background on the screen in the current picture. 
FREQUENCY/PHASE
These  adjustments,  available  for  progressive  signals  and  for 
signals from Pc, ensure correspondence  between the number 
of pixels making up the signal and the number of pixels making 
up  the  projected  image.  These  parameters  do  not  normally 
require adjustment because the system checks the input signal 
and automatically sets the most suitable values. 
However, if the image appears disturbed (loss of position within 
the equidistant vertical bands or instability and lack of sharpness 
on the narrow vertical lines) it may help to prompt the system to 
repeat the input signal analysis and determination of the best 
parameters  by  calling  the  automatic  adjustment  procedure 
with the AUTO key on the remote control or on the keypad. 
If  the  automatic  procedure  fails  to  have  the  required  effect, 
enter  the  frequency  and  phase  values  manually  and  ap-
proach  the  screen  sufficiently  to  observe  the  effects  of  the 
adjustments.
Y / C DELAY
In the case of Video and S-Video signals, it may be necessar y 
to correct horizontal colour misalignment within the projected 
image. For a given video standard (e.g. PAL or NTS c) the stored 
value does not normally require further fine-tuning, unless the 
source or connection cable has changed.

The event you are unable to centre the image within the screen 
area,  tilt  the  projector  until  the  image  is  correctly  positioned. 
Any  keystone  error  can  be  removed  by  the  Keystone  adjust-
ment in the Set up menu. The keystone adjustement helps to 
compensate possible horizontal tilts of the projector.
LENS
The  ZOOM  adjustment  impacts  on  the  motorized  zoom  lens 
allowing to increase or decrease the dimension of the projected 
image.
The FOcUS adjustment impacts on the motorized lens focus, 
allowing to obtain the highest definition on the projected image, 
an accurate focus setting should allow the viewer to distinguish 
each pixel that create the image one from another.
In  association  with  the  ZOOM,  FOcUS  and  LENS  SHIFT  adjust-
ments the  c3X system provides three test patterns to be used 
if there is no suitable signal available to set up these param-
eters.
The LENS SHIFT adjustment allows to move horizontally (keys ◀ 
and ▶) and vertically (keys ◀ and ▶) the lens, in order to center 
the image.
