Mic/Line Input 1
A dynamic or condenser microphone can be connected to the Mic/Line 1 input, which
can serve as the conferencing mic. The Mic/Line input 1 is sent via the USB output to the

Audio Line Inputs
The following MediaPort 300 audio line inputs are typically used for program audio:
USB Playback — The MediaPort 300 is the computer USB audio playback device.
•
• Line Input 2 (analog) — The MediaPort 300 accepts balanced or unbalanced line level
signals.
• HDMI — The MediaPort 300 accepts 2-channel PCM audio signals from this digital
connection.
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 Host Input
The local computer can be used as a program audio source via the USB connection.
Line Input 2 (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.
