Mic/Line Input; Usb Communications Input; Audio Line Inputs; Usb Playback Input - Extron electronics MediaPort 200 User Manual

Mic/Line Input

A dynamic or condenser microphone can be connected to the Mic/Line input that serves
as the conferencing mic. The Mic/Line input is sent via the USB output to the computer
to be sent to the far end. The Mic/Line input is also sent to the Aux output, which can
be connected to a sound reinforcement voicelift system if local speech reinforcement is
needed.
NOTE: Mic/Line Input signal is not sent to the Analog Line Output of the MediaPort 200.

USB Communications Input

USB communications audio from the far end is mixed with the line inputs and sent to the
analog Line output for local sound reinforcement.

Audio Line Inputs

The following MediaPort 200 audio line inputs are typically used for program audio:
•
•
•
These line inputs are mixed to the USB output and sent to the far end and to the Analog
Line Output. The Analog Line Output signal path also mixes in the USB communications
audio from the far end, while the USB audio output path does not.

USB Playback Input

The local computer can be used as a program audio source via the USB connection.
This PC program audio is independent of the far end USB communication audio sent
from the UC application to the MediaPort 200, allowing program audio and far end USB
Communication audio to be mixed on separate channels in the PCS software.
NOTE: If using a Web-based soft codec, communications audio is sometimes recognized

Line Input (analog)

Connect an analog program audio source to the Line input. This could be the output of
an auxiliary program source such as a CD or DVD player, mobile device, media player, or
switcher.

HDMI Input

If the device connected to the HDMI input has embedded microphone audio, it is important
to mute the audio on the HDMI input. All near end speech audio should come from the
microphone connected to the Mic/Line Input.
USB Playback — The MediaPort is the computer USB audio playback device.
Line Input (analog) — The MediaPort accepts balanced or unbalanced line level
signals.
HDMI — The MediaPort accepts 2-ch PCM audio signals from this digital connection.
