Best Practices For Great Audio

We have a few recommendations for getting the most out of your Mevo's audio options depending on your venue and setup.

Built-in Mevo Audio

If you are using the Mevo’s built-in microphone, be sure to place the Mevo close to your subjects, no more than five to ten feet away. The Mevo and its built-in mic work best when it is on-stage, and close to the action.

The Mevo’s microphone is directional to the space directly in front of it, but may still pick up general room noise. The closer the mic is to your subjects, the more it will filter out noise or chatter behind or to the side of it.

The Mevo's default built-in microphone has automatic gain adjustment, and will adjust itself for the louder or quieter audio of your live event. 

You may also manually set the Mevo's built-in microphone's gain adjustment to fit your preference. Use the slider bar to raise or lower your audio's gain adjustment.  

How to Use an External Audio Source with Mevo

You may, instead, choose to use an external audio source with your Mevo, via your iOS device's TRRS 3.5mm plug.

The TRRS plug is a specific type of plug. The easiest example of what one looks like is your iOS device's supplied earbuds.

If you look at the plug on your iOS earbuds, you will see three thin rings, and four wider chrome rings.

Any audio output you want to use with Mevo must have rings as shown above, as this is an iOS device requirement. 

The following two photos are plugs that are not compatible for bringing external audio into your iOS device. If your microphone or mixer's output looks like these, they will not output audio to your iOS device.

Only 2 thin rings, 3 chrome rings.

No thin rings.

Be sure to check out our list of tested and supported external audio adapters and devices. 

Plug your TRRS 3.5mm audio input into your iOS device's headphone jack.

Once you are in the Audio Mixer, you will see "Mevo" is selected, and "iPhone" is greyed-out.

Tap where it says "iPhone," to start using your external audio input. 

USB Audio inputs can now also be accepted via Mevo Boost or a USB OTG cable.

You will see your audio levels in the green bars to the right.  

When using an external audio source, you cannot also hear your audio output through the app. You will have to monitor the audio on your live stream. 

You can adjust your audio gain up and down with the slider bar to further adjust your levels. 

Tips for Various Production Scenarios

If you decide to use an external microphone, you will have a greater range of choices for getting high quality audio.

Here are some general audio tips for different event scenarios:

 A panel presentation. Multiple speakers. Quieter room.

If you have a group of speakers sitting at a table, or standing on a stage, your best solution would be to use small microphones that clip-on to the speaker’s shirt. These mics are called lavalier microphones, and come in a variety of types, including wireless.

In this scenario, you would need one lavalier microphone (commonly referred to as a “lav mic”) per speaker. This audio is short range and focused on picking up only the audio of the speaker it’s attached to. This setup is common for all television interviews, as the lav mic is high quality, filters out most room chatter and noise, and is inconspicuous.

These microphones would then be added to a mixer, which is ideally run by a separate person. This way, the mixer can be used to bring different mics up or down, depending on who is speaking. Mixers have an output, from which you can run a stereo cable into your iPhone, so that your Mevo gets this clear, mixed audio feed.

When buying lav mics, check to see if they run on battery power, or phantom power. If phantom power, you will need a mixer that will provide the power to the mics.

Generally, most mixers have a quarter-inch stereo output, and the iPhone has an eighth-inch TRRS input, so you would need a cable of appropriate length with a ¼” end and a ⅛” inch TRRS end.

A music event. Loud room.

Most live event venues have a sound board. If you have access to this board, the best solution would be to get an audio cable with a 3.5mm TRRS end and take the fully mixed board output directly into your iPhone, to mix into your Mevo’s audio recording.

If you do not have access to the board feed, you should consider a shotgun microphone. This is a long microphone, usually covered with a windscreen, that can be more or less directional, depending on the mic, but generally covers a room’s sound with a focus toward what it’s pointed at.

In the scenario with a shotgun mic, you would try to center yourself in the room, and point the mic toward the stage. The advantage of a shotgun mic is that you generally just need one, as it will cover a wider area while still filtering out side and background noise and chatter.

When buying a shotgun mic, check to see if they run on battery power, or phantom power. If phantom power, you will need to provide the power to the mic.

You will want a shotgun mic that has an ⅛” TRRS end, or get an adapter if needed. Many shotgun mics use XLR connections.

You can find a variety of both lavalier and shotgun microphones retailers like Amazon, Best Buy, and BH. Your audio setup can get as complicated as you have the time and budget for, but the solutions described above should provide clear audio and a simple workflow for your event.
