CHOOSING THE RIGHT VIDEO OUTPUT
IMPORTANT
Y/C output (S-VHS - #37 and #38)
RGBS output (#41)

VZ-17:
On the VZ-17 the RGBS-signal is actually only a converted Y/C-signal. (As the VZ-17 has a 1-chip camera and no 1-
chip camera has a true RGBS output). This output is intended for units which do not have Y/C-input. The quality is
better than composite video but not better than Y/C !
Most RGB-monitors or projectors use a separate Sync connection. For units without a separate Sync connection
the Sync Signal can be added to the Green-signal.
The "Sync on green" function can be switched on and off by simultaneously pressing the following three keys:
IMAGE (#17), FOCUS near (#19), FOCUS far (#19). The factory setting is "Sync on green - off".
If "Sync on green" is switched on, make sure that no separate sync cable is connected - the result
could be a picture with too much green!
Component output (#41 - VZ-37 only)
The RGBS output of the VZ-37 can be switched to Component output (YUV) by simultaneously pressing the following
three keys: IMAGE (#17), IRIS dark (#24), IRIS bright (#24).
The connections are the following: Red=R-Y, Green=Y, Blue=B-Y
Composite video output (#32)
Only use this output if the display device does not have Y/C or RGBS input. This is the oldest standard with the lowest
bandwidth the quality is not as good as with the other outputs.
Preview video output (#31)
This is a composite video output for a control monitor. It's the only output that is not switched off, when the IMAGE key
(#17) is used. Do not use this output for the audience's monitor or projector!
For live image projection it is recommended to use the Y/C output as the signal passes a sharpness enhancer. It even
looks better than with the RGBS output of the VZ-37. Only the Component output (YUV) of the VZ-37 offers a better
quality than the Y/C-output.
The VZ-37 offers a true RGBS-signal. Red, Green and Blue are directly connected to each of the 3 chips of the
camera. As a result this output offers the best color reproduction. This signal is also recommended for image
processing as it is the original (unprocessed) signal.
(On the VZ-37 this output can be switched to YUV - see below)
