Microphone and Speaker

GVC3200/GVC3202 is equipped with a built-in microphone. Alternatively, you can connect external audio
devices to GVC3200/GVC3202 as audio input/output sources. It is recommended to use the external
speaker that comes with your GVC3200/GVC3202 package for better compatibility.
If the external speaker supports Bluetooth, users could also pair and connect the speaker to the
GVC3200/GVC3202 via Bluetooth. This will provide better mobility and make cabling easier when deploying
the GVC3200/GVC3202 conference system in your conference room.
When there are multiple audio devices connected to the GVC3200/GVC3202, the users could configure
the audio device priority from LCD Menu->Settings->Audio->Audio Priority, or from web UI->Device
Control->Audio Control: "Audio Device". Please refer to more details in "Audio Device" option.
