Please note that using a longer cable or a non-
ALTINEX cable for remote horizontal position
could affect the stability of the picture by creating
unwanted jitter.
4.5 MOUNTING CAPABILITY
The VA6822 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 under the table mounts, optional
brackets like the TM1271, TM1272, TM1273, or
TM1274 can be used.
4.6 POWER REQUIREMENTS
The VA6822 may be used anywhere in the world
where the voltage is from 100 to 240 volts AC at
50/60 Hz. For the safety of the user and for
protection of the unit, make sure that the input
voltage of the VA6822 is in the range of 100 to
240VAC. The unit is auto-switchable so that no
user adjustments are necessary when switching
from 120 to 220VAC for different countries. The
LED located on the front and back panel should
light RED or GREEN when valid power input is
transmitted to the VA6822.
4.7 BANDWIDTH
The typical bandwidth of the VA6822 is 425 MHz.
The minimum bandwidth is 350 MHz. This
exceptionally high bandwidth allows passing of the
third harmonics of the video signal, thus
maintaining the highest quality of the video signal.
The VA6822 can easily pass signals from VGA
through UXGA. The signal quality at the display/
target will depend upon the type and quality of
cable used.
4.8 EQUALIZATION
The VA6822 has a high bandwidth of 350 MHz
allowing high-resolution signals to pass through
the unit without attenuation for a long run. For
cable runs longer than 100ft, the signal attenuates
at medium and/or high frequency. To correct this
cable attenuation problem, the VA6822 is
equipped with a feature called
Equalization/Peaking on the front panel for each
video signal: red, green, and blue. These
channels can be equalized individually. Starting
from step one on the dial, equalization can be
increased to step E for longer cable lengths in
increments of 25ft with a slotted screw driver.
Before increasing to the next level, check the
sharpness of the picture on the display. If the
picture is sharp enough, do not increase it to the
next level.
With a good quality of output cables and a strong
input signal, the VA6822 can drive signals up to
300ft with minimal loss of the signal quality.
