You may use an external audio source with your Mevo, via your mobile device's 3.5mm port, charging port, or the USB port in a Mevo Boost.
To bring audio in through your device's headphone port, you need a device that outputs audio via a 3.5mm TRRS plug. The easiest example of what one looks like is your mobile device's supplied earbuds, most of which include a built-in microphone. If you look at the plug on these earbuds, you will see three thin rings in between four wider chrome rings, indicating the device can sent audio out in addition to receiving audio.
If your 3.5mm plug does not have this appearance (i.e. only 2 rings), then your mobile device cannot receive audio from it.

Plug your external audio input into your mobile device. Once you have connected your Mevo to your app, open the main menu by tapping the More Options icon (three dots) in the bottom right corner of the live edit view. The below menu will appear.
Next, tap on the microphone icon to open the Audio Mixer.
In the Audio Mixer, you will see "Mevo" is selected, and "iPhone" is greyed-out (if you are using an Android device, this will say "Phone" instead).
Tap "iPhone" ("Phone" on Android) to select your external audio input. If you don't have any devices connected to your mobile device, your device's built-in microphone will be used instead.
You will see your audio levels in the green bars to the right.
When inputting a stereo signal into the iPhone through the 3.5mm TRRS input, the output will be a mix of the left and right audio channels. When inputting a stereo signal into the iPhone through the Lightning port, the output will remain in stereo.
When using an external audio source, you should mute your audio output on the app by tapping the speaker icon on the right side; this will help avoid an echo in your stream and recording. In this instance we recommend pushing a test stream to your destination (e.g. stream to Facebook but select Only Me as the audience) and checking your audio quality there prior to your event.
You can adjust your audio gain up and down with the slider bar to further adjust your levels.
