Input BNC Configuration
Many video sources have an associated video source 
that contains alpha (transparency) information. You 
must configure the switcher to use the correct alpha 
source. Once you associate a video and alpha 
source, they are linked and used for Auto-Select 
keying. 
Alpha sources are designated as shaped or linear 
(unshaped). Shaped sources convert partial 
transparency to either fully transparent or fully 
opaque, giving the video signal well-defined edges.
Linear (unshaped) sources use the full range of 
transparency in the alpha channel to give smooth 
transitions between transparent and opaque areas. 
Use linear if you are unsure which setting to use.

an unshaped (linear) alpha source.
• Shpd1 - Shpd12 — The selected input is 
used as a shaped alpha source.

If you are using standard definition sources, use 
the SD ASP knob to select the aspect ratio of the 
video signal. You can choose from the following:

Output Configuration
The switcher has the following outputs:
• 2 Program Out HD-SDI
• 1 Preview Out HD-SDI
• 3 Auxiliary Out HD-SDI
• 1 Analog (NTSC or PAL) Out
The analog output allows the switcher to output 
signals in NTSC and PAL formats. It can be routed 
from the Preview, Program, or any of the primary 
inputs. The analog output is not aspect ratio 
converted. Downconversions from 16:9 HD sources 
display as 16:9 SD video.
