Power up State
When you first power up the SE-800, you will need to make channel assignments and set audio levels.
Transition and effect settings are not retained please refer to Preset Bank on Page 35 for function keys
setup (see Using Transitions , page 35 and Using Effects , page 41 for details).
At power up, channel A will be the selected Main Video Source and channel B will be the selected Sub Video
Source.
Settings that are retained are: input formats for all channels; color correction settings; background color; and
transitions or effects that have been saved into the Preset Bank.
Connecting Video Sources
There are three types of plugs used for video signals on the SE-800: BNC, S-video, and DV.
BNC connectors look like this on the cable end. The connector slides over the connector on
the SE-800 and is locked in place with a push in and clockwise turn. The big virtue of these
connectors, which are the standard for almost all professional video applications, is that
they lock in place and cannot be accidentally dislodged.
S-video plugs (also known as Y/C) have 4 tiny pins in them, which carry a separated Y
(luminance) and C (chroma) video signal and provide a much better quality video signal
than composite. These plugs have a tiny bar in them to assure correct alignment in the
socket. They need to be pressed firmly in place, but very carefully, as the little pins can
bend easily. Align plug and socket and push straight in, firmly.
DV plugs come in 4 pin and 6 pin connector sizes. The SE-800 uses the 6-pin variety. The
6-pin size is typically found on computer interfaces, hard drives, CD burners, etc. You’ll
notice that one side of the plug is indented. This fits into the socket on the SE-800 one way,
and one way only. It is a tight fit, for security and stability, so push straight and firmly, but
don’t force it without first making sure it is correctly oriented. If you need to run a DV cable longer than 20
meters (roughly 65 feet), you must use a DV repeater, such as Datavideo’s VP-332 or VP-314 (page 62), to
avoid signal loss caused by the distance. You can also use Datavideo’s DV Repeater /DA (distribution
amplifier) to have more than one DV output from the switcher. Add the DV Repeater/DA and you have five
DV outs.
Connecting Audio Sources
The SE-800 uses 2 kinds of plugs for audio connections: RCA and 1/4 inch jack plugs. There are lots of
different names for these plugs. Fortunately for us all, they are not easily confused in the size and shape
departments, so we’ll show you some pictures.
