PRECAUTIONS

WARNING!

RISK OF ELECTRIC SHOCK

DANGEROUS VOLTAGE INSIDE

Make sure that sufficient air circulation for cooling the unit is possible (ventilation slots on the
left and right side of the unit)

If the Visualizer is not used for a long time turn off the main power switch (#34)!
If there is any abnormality (abnormal noise, smell, smoke etc.) turn the power off immediately

and contact your Visualizer dealer!
USE THIS MACHINE ONLY WITH THE CORRECT VOLTAGE AS

SHOWN ON THE TYPE LABEL !
Do not use a damaged power cord. This may cause short circuits or electrical shocks!
Do not modify the Visualizer or operate it without the cover panel firmly in place, to prevent danger!
DO NOT EXPOSE THE UNIT TO EXTREME HEAT OR MOISTURE !
Do not expose the Visualizer to water, metallic objects or any flammable material.
Do not place liquids or wet objects on the working surface! Put them in front of or behind the

unit and use it as a camera. If you work with wet hands, cover the remote control with plastic wrap!
DO NOT CARRY THE VISUALIZER HOLDING IT ONLY BY ITS MIRROR ARM (#1) !

DURING TRANSPORTATION PROTECT THE UNIT FROM EXCESSIVE SHOCKS !
Avoid installing the Visualizer in environments where there is radiation.
Avoid installing the Visualizer in locations exposed to strong magnetic fields or electrical

currents. This could cause monitor image distortion or damage to the CCD camera.

CHOOSING THE RIGHT VIDEO OUTPUT

(of VZ-17 or VZ-37)

Y/C output (S-VHS - #37 and #38)

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.

RGBS output (#41)

VZ-37:

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

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)

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 !

IMPORTANT

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 bandwith 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!

CONNECTIONS (VZ-47)

#34 Main POWER switch
#35 FUSE (see page 13)
#36 POWER connection
#39 SERIAL port for external remote controlling
#40 PARALLEL port for external remote controlling

RGBS OUTPUTS (VZ-47)

The VZ-47 outputs an RGBS-signal with 50 Hz and 31.25 kHz.
This is a DATA-RGBS signal which can be used by most data-projectors or computer-monitors.

However, you can NOT connect the VZ-47 to a video monitor or a video-projector which can not project
computer data (with a resolution of at least 782 x 582 pixels or 31.25 kHz)

#42 RGBS-output (switchable - details see below)
#43 PREVIEW SVGA-output (not switchable - details

see below)

#44 SVGA-output (switchable - details see below)

IMPORTANT

Synchronization of a projector or monitor:

Most projectors or computer monitors adjust themselves automatically when the VZ-47 is connected.
However some projectors don't automatically adjust to the signal output of the VZ-47. As it is not 100%

SVGA compatible. The SVGA standard is 800x600 pixels at 60 Hz and the signal output by the VZ-47
is 782x582 pixels at 50Hz.You may have to go into the setup menu of your data-projector or computer­monitor to adjust these settings manually.

The factory-settings of the sync-outputs is HD/VD (i.e. separate horizontal and vertical sync-impulses) and sync­on-green off. This format is the same as the one used in the computer-industry so there should be no problems
with the most multiscan-monitors or projectors.

However, if your display-device does not support separate sync-inputs but has only one sync-input (normally
marked with S) you should switch the Visualizer to CSYNC (i.e. the combined vertical- and horizontal-sync­impulses are output on the S/HD-connector). You can switch between CSYNC and VD/HD by pressing the
following three keys simultaneously: . IMAGE (#17), IRIS dark (#24), IRIS bright (#24)

If you want to use sync-on-green you can change between sync-on-green on and off by simultaneously pressing
the following three keys . You can also change this setting in
the camera-menu. When sync-on-green is switched on you need only to connect R, G and B. Monitors which do
not support this mode often display a green picture.

Please note that the sync-outputs are the same on all three outputs (5 x BNC, Preview and RGB). So if you use
multiple display-devices you should use a mode which is supported by all display-devices. Many modern monitors
or projectors automatically detect the sync-mode so they should be able to work with most of the above Visualizer­settings. On some display-devices you can also change manually between these modes.

IMAGE (#17), FOCUS near (#19), FOCUS far (#19)

SWITCHABLE OUTPUTS (all Visualizers)

All outputs of the WolfVision Visualizers - except the Preview output (#31 or #43) - are switchable. Use the
IMAGE key (#17) to switch the signal supplied from these outputs on and off. Independently an image is always
output by the Preview output (#31 or #43). This output can be used for a control monitor. A constant sync signal
is supplied to all switchable outputs (even in the image off mode) eliminating monitor image distortions when
switching.
When the output signal is switched off the IMAGE key on the control panel is illuminated red.
