1-3Digital Display Scaler • Introduction
The scaler also features a zoom function, up to 200%, that maintains the original
aspect ratio. The zoom function makes the scaler ideal for video wall applications
using four displays and four DDS 402s zoomed to 200%.
The scaler features four levels of horizontal filters, which help prevent detail loss,
and ten levels of vertical filtering, which reduce flicker.
Other picture controls that the DDS 402 provides are centering, size, brightness,
and contrast adjustments. The scaler also has a top and bottom line blanking
function.
The DDS 402 is housed in a rack-mountable, 1U high, 17.5" wide metal enclosure.
With the included mounting brackets, the scaler can be rack mounted, or mounted
under a desk or table, or against a wall or the side of a desk. The DDS 402 has an
internal 100VAC to 240VAC, 50/60 Hz, 30 watts auto-switchable power supply that
provides worldwide power compatibility.
