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