Altinex VA6822 manual Interfaces, Mounting Capability, Power Requirements, Bandwidth, Equalization

INTERFACES

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

6

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.
