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.

• Auto-Select keys, refer to the section “Keying
Overview” on page 18.

signal.
• Lin1 - Lin12 — The selected input is used as
an unshaped (linear) alpha source.
• Shpd1 - Shpd12 — The selected input is

6. 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:
• 16:9
• 4:3

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.
