Extron electronic DDS 402 manual Features

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.
