The Quadra is a high performance, four channel multi-format up/down
converter with a full range of digital and analog input and outputs. The unit
provides four independent processing channels, each with the ability to select
between three standard inputs and one optional input. The following sources
can be used as inputs for each channel:
• RGB / YP
b
P
r
component
• Composite video
• S-Video
• DVI (optional)
When using DVI inputs and outputs, the Quadra offers a completely digital
path from signal source to display. Typically, Quadra is used as an advanced,
image “gearbox,” with the ability to convert each input to a different user-
defined output format.

All output signal parameters are user-selectable, including line rate, frame rate,
interlacing, blanking and sync type.
Additionally, Quadra’s pan and zoom functions enable you to selectively
extract any portion of an input signal for cropping or aspect ratio adjustment.
Conversion to a lower line rate format can be accomplished by extracting a
portion of the original signal, by down-converting the entire raster or by a
combination of both methods.
