The TE40/TE50/TE60 endpoint provides XLR, RCA, and microphone array ports.
You can connect an audio input device with an XLR or RCA connector, such as a microphone, mobile phone, and computer, to the XLR or RCA port on the endpoint, and connect Huawei VPM220 and VPM220W to the microphone array port.
You can also connect an audio mixing console to the TE50.
To disable all audio input using one button on the TE series endpoint, use either of the following methods:
On the web interface, choose System Settings > Input/Output > Audio, and set Switch controls to All audio inputs.
On the user interface, choose Advanced > Settings > Audio > Audio Input and set Switch controls to All audio inputs.
If the audio output port of the gooseneck microphone is of the same type as the audio input port of the ViewPoint 9039S, the two ports can be connected. If the two ports are of different types, connect them through the tuning console.
To adjust the audio input volume of an endpoint:
Log in to the endpoint's web interface, choose Device Control > Audio Control and increase the gain of the audio input port. If the endpoint connects to a tuning console, you can adjust the gain on the tuning console.
