Mediaport 200 Signal Flow; Matrix Routing - Extron electronics MediaPort 200 User Manual

MediaPort 200 Signal
Flow
This section provides a more advanced understanding of the MediaPort signal flow. As
stated, MediaPort is designed to fit seamlessly into a number of common conferencing
applications, with little or no additional configuration other than setting proper gain structure
and adjusting run‑time mix level controls.

Matrix Routing

Figure 6 is a basic signal flow block diagram showing the MediaPort default configuration
and available processing. The Matrix Routing Table is a truth table that illustrates
MediaPort 200 routing. Viewing the mix matrix routing from the perspective of the outputs:
•
•
•
•
USB Out
Set to Dual Mono mode (default), left and right signals are summed. The following
•
line inputs are routed to the USB Out L/R:
USB Playback
•
HDMI In
•
Line In
•
Mic/Line In is routed to USB Out L/R
•
NOTE: USB Communications audio is never routed to USB Out.
Line Out
Set to Stereo Mode (default). Line input left is routed to Line Out L; Line input
•
right is routed to Line Out R. The following line inputs are routed to Line Out L/R:
USB Playback
•
HDMI In
•
Line In
•
USB Communications – there is an option to mute this signal to the line output
•
Includes both line input signals and USB communications signal
•
NOTE: Mic/Line input is not routed to Line Out
AEC Ref Out — only the USB Communications signal, summed to mono, is routed to
the Ref Out
Aux Out — only the Mic/Line Input signal is routed to the Aux Out
