Precautions
This symbol is intended to alert the user of important
operating and maintenance (servicing) instructions
in the literature provided with the equipment.
This symbol is intended to alert the user of the
presence of uninsulated dangerous voltage within
the product's enclosure that may present a risk of
electric shock.
Caution
Read Instructions • Read and understand all safety and operating
instructions before using the equipment.
Retain Instructions • The safety instructions should be kept for future
reference.
Follow Warnings • Follow all warnings and instructions marked on the
equipment or in the user information.
Avoid Attachments • Do not use tools or attachments that are not
recommended by the equipment manufacturer because they may be
hazardous.
Warning
Power sources • This equipment should be operated only from the power source
indicated on the product. This equipment is intended to be used with a main
power system with a grounded (neutral) conductor. The third (grounding) pin is
a safety feature, do not attempt to bypass or disable it.
Power disconnection • To remove power from the equipment safely, remove all
power cords from the rear of the equipment, or the desktop power module (if
detachable), or from the power source receptacle (wall plug).
Power cord protection • Power cords should be routed so that they are not likely to
be stepped on or pinched by items placed upon or against them.
Servicing • Refer all servicing to qualified service personnel. There are no user-
serviceable parts inside. To prevent the risk of shock, do not attempt to service
this equipment yourself because opening or removing covers may expose you to
dangerous voltage or other hazards.
Slots and openings • If the equipment has slots or holes in the enclosure, these are
provided to prevent overheating of sensitive components inside. These openings
must never be blocked by other objects.
Lithium battery • There is a danger of explosion if battery is incorrectly replaced.
Replace it only with the same or equivalent type recommended by the
manufacturer. Dispose of used batteries according to the manufacturer's
instructions.
Ce symbole sert à avertir l’utilisateur que la
documentation fournie avec le matériel contient des
instructions importantes concernant l’exploitation
et la maintenance (réparation).
Ce symbole sert à avertir l’utilisateur de la présence
dans le boîtier de l’appareil de tensions dangereuses
non isolées posant des risques d’électrocution.
Attention
Lire les instructions• Prendre connaissance de toutes les consignes de
sécurité et d’exploitation avant d’utiliser le matériel.
Conserver les instructions• Ranger les consignes de sécurité afin de
pouvoir les consulter à l’avenir.
Respecter les avertissements • Observer tous les avertissements et
consignes marqués sur le matériel ou présentés dans la documentation
utilisateur.
Eviter les pièces de fixation • Ne pas utiliser de pièces de fixation ni
d’outils non recommandés par le fabricant du matériel car cela
risquerait de poser certains dangers.
Avertissement
Alimentations• Ne faire fonctionner ce matériel qu’avec la source d’alimentation
indiquée sur l’appareil. Ce matériel doit être utilisé avec une alimentation
principale comportant un fil de terre (neutre). Le troisième contact (de mise à la
terre) constitue un dispositif de sécurité : n’essayez pas de la contourner ni de la
désactiver.
Déconnexion de l’alimentation• Pour mettre le matériel hors tension sans danger,
déconnectez tous les cordons d’alimentation de l’arrière de l’appareil ou du
module d’alimentation de bureau (s’il est amovible) ou encore de la prise secteur.
Protection du cordon d’alimentation • Acheminer les cordons d’alimentation de
manière à ce que personne ne risque de marcher dessus et à ce qu’ils ne soient pas
écrasés ou pincés par des objets.
Réparation-maintenance • Faire exécuter toutes les interventions de réparation-
maintenance par un technicien qualifié. Aucun des éléments internes ne peut être
réparé par l’utilisateur. Afin d’éviter tout danger d’électrocution, l’utilisateur ne
doit pas essayer de procéder lui-même à ces opérations car l’ouverture ou le
retrait des couvercles risquent de l’exposer à de hautes tensions et autres dangers.
Fentes et orifices • Si le boîtier de l’appareil comporte des fentes ou des orifices,
ceux-ci servent à empêcher les composants internes sensibles de surchauffer. Ces
ouvertures ne doivent jamais être bloquées par des objets.
Lithium Batterie • Il a danger d'explosion s'll y a remplacment incorrect de la
batterie. Remplacer uniquement avec une batterie du meme type ou d'un ype
equivalent recommande par le constructeur. Mettre au reut les batteries usagees
conformement aux instructions du fabricant.

IN3252HR • Introduction
The IN3252HR is an ultrahigh resolution RGBHV video
distribution amplifier (DA) with gain and peaking controls. It
accepts RGBHV, RGBS, RGsB, RsGsBs, component video,
S-video, as well as high resolution monochrome video and
composite video baseband signals, and distributes the signals to
two separately buffered outputs and one passive loop-through.
The DA is powered by an external power supply, which is
included with the unit.

Input coupling jumpers (J1, J4, and J6)
To insure the best picture quality, inputs are DC coupled as a
factory default.
If the source device has a high DC offset that causes picture
distortion and/or instability, change the jumpers to AC
coupling.

Potentiometer Adjustments
With an oscilloscope
1. Feed a grayscale signal from an Extron VTG 300/400 or
other A/V test generator to the input of the IN3252HR DA.
2. Remove the far end of the green output cable from the
display and connect it to the oscilloscope with 75 ohm
termination.
3. Adjust the green gain control to achieve 0.7 Vp-p for the
white bar of the test pattern.
4. Repeat steps 2 and 3 for the red and blue channels.
5. Adjust the peaking control by connecting the oscilloscope
back to the far end of the green output cable and adjusting
the peaking potentiometer until no overshooting or round
corners appear on the test pattern.
6. Plug the far end cables back to the display device.
