You may use an external audio source with your Mevo, via your mobile device's 3.5mm port, lightning 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 or via a lightning plug (iOS devices only).
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.
If your mobile device does not include a headphone port, use the headphone adapter that comes with it to attach a TRRS plug to your device. Additionally, some supported audio devices attach via lightning or USB. Be sure to review our supported external audio devices here.
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 (•••) in the bottom right corner of the live edit view. The below menu will appear.
Tap the microphone icon on the left side to open the Audio Mixer.
In the Audio Mixer, you will see Mevo is selected by default and iPhone is grayed out (if you are using an Android device, this will say Phone instead).
Tap iPhone (Phone on Android) to use 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 mono mix of the left and right audio channels. When inputting a stereo signal into the iPhone through the Lightning port or into a Mevo Boost via USB, 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. Otherwise, you can control your audio device just as you would in any other production setup.
