MPX Plus 866 A Media Presentation Matrix Switcher • Installation 2-4
PRELIMINAR
Y
Low resolution video group
The switcher can connect to up to as many as six S-video and/or composite video
sources and output to as many as six video devices.
c
Video Input 9 and Video Input 10 (composite video inputs) —
Connect composite video sources to these female BNC connectors.
N Video Input 9 serves as a timing reference for all other low
resolution video group inputs. If one of the inputs is synced to a
blackburst generator, connect that source to input 9.
d
Input 11 through Input 14 —
S-video inputs — Connect an S-video source to a pair of female
BNC connectors. Connect luma (Y) and chroma (C) as shown at
right.
Composite video inputs — Connect a composite video source to
the Video (top) connector in a pair of female BNC connectors as
shown at right.
e
Composite video outputs (Output 7 and Output 8) —
Connect composite video displays to these female BNC connectors.
N If the input tied to Output 7 or Output 8 is S-video, the switcher
encodes the input to composite video.
If the tied input is composite video, the switcher passes it through to the output
with no processing.
f
S-video outputs (Output 9 and Output 10) —
Connect S-video displays to these female BNC connectors.
N If the input tied to Output 9 or Output 10 is composite video, the
switcher decodes the input to S-video.
If the tied input is S-video, the switcher passes it through to the
output with no processing.
g
Pass-through outputs (Output 11 and Output 12) —
Connect S-video or composite video displays to these
female BNC connectors. Connect S-video Y and C or
composite video as shown at right.
N The switcher passes the tied input to these outputs with no
signal processing; an S-video input is output as S-video, a
composite video input is output as composite video.
Audio input and output connections
By default, the audio ties follow the video ties. Audio breakaway, which can
be activated via the optional front panel or under Ethernet or RS-232 control,
allows you to select from any one of the audio input sources, regardless of video
group, and route it separately from its corresponding video source.
N Audio ties can be made only to outputs in the computer/audio group (outputs 1
through 6).
The audio level for each input and the volume level for each output can be
individually set via the front panel or Ethernet or RS-232 control. See chapter 3,
“Operation”, chapter 4, “SIS Programming and Control”, chapter 5, “Switcher
Software”, and chapter 6, “HTML Operation” for details.
