MediaPort 200 Signal Flow

This topic provides a more advanced understanding of the MediaPort signal flow. As stated,
MediaPort fits into multiple conferencing applications, with little or no additional configuration
other than setting proper gain structure and run-time mix level controls.

default configuration and available processing. Figure 3 below is an audio matrix routing
table that displays MediaPort 200 audio routing. Viewing the mix matrix routing from the
perspective of the outputs:

USB Playback
HDMI
Line In
USB Communications
Mic/Line In
*Y = Routing with USB Communications set to "Line Out + Ref Out"
N = Routing with USB Communications set to "Ref Out Only"

USB Out
Set to Dual Mono mode (default, stereo available), 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, dual mono available). Line Input L is routed to Line
•
Out L; Line Input R 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 (unless USB
•
communications is muted), which is useful when connected to an external DSP.
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.
