4.4 HORIZONTAL POSITION ADJUSTMENT
Most monitors and projectors have the ability to
adjust the horizontal position of the image, but
sometimes it is helpful to be able to control this
feature at the interface. This control is especially
useful when multiple computers are switched to
a single display and the horizontal positions from
each computer are slightly different.
By keeping the VA6834FC’s horizontal position
control dial located in the center position, the
image on the display should be adjusted using
the monitor or projector control. If it is
necessary, adjust the horizontal position of the
image with the
VA6834FC’s horizontal position
control dial.
To turn off the horizontal position control, turn
the adjustment dial fully to the right until a
“clicking sound is heard.
4.5 HORIZONTAL DELAY REMOVAL
The VA6834FC offers the ability to by-pass
horizontal delay. This may be necessary when
interfacing with projectors or monitors with
sensitive sync inputs, particularly with LCD type
projectors. By turning the horizontal position
adjustment dial fully to the right, the control will
“click” into a locked position. In this position, the
VA6834FC outputs the same sync type as that
which is fed into it from the source. In this
setting, the
VA6834FC will not provide horizontal
positioning. Horizontal position adjustment
must be made at the display.
4.6 POWER REQUIREMENTS
The VA6834FC may be used with either 120V or
220V throughout the world for ease of use.
Always make sure that the fuse box window
above the power input connector displays the
proper voltage. To change the setting, unplug
the
VA6834FC , and squeeze the clips on either
side of the fuse box. Pull out the fuse holder and
turn it 180 degrees, resetting it with the proper
voltage shown through the window. Re-insert
the fuse box making sure that the side clips of
the fuse box lock securely into place.
4.7 MOUNTING CAPABILITY
The VA6834FC can be easily mounted into an
equipment rack. Four mounting holes are
provided on each side of the unit. To mount a
single unit, use Altinex 19”-1U Rack Mount Ears
(part #
DA1294FC) . To mount two units in
tandem, use an Altinex 19”-1U Rack Mount
Shelf (part #
DA1293FC ). For mounts under the
table, optional brackets, such as the TM1271 ,
TM1272 , TM1273, or TM1274 can be used.
4.8 BANDWIDTH
The typical bandwidth of the VA6834FC is
425 MHz. The minimum bandwidth is 350 MHz.
This exceptionally high bandwidth allows the
passing of the third harmonics of the video
signal, thus maintaining the highest quality of
the input signal.
