Ambient Mics for Your Video Live Stream Mix

by | Production, Video, Video Connections

One of the most disappointing things when you hear your live stream mix for the first time is how it sounds nothing like it sounded in the room. I’ve got some good news for you. Your room mix was way better than the live stream sounded. The reason it sounds nothing the same is because you’re missing all the sound reflections and acoustical energy that exists in the room. You can’t exactly replicate this in a live stream mix, but you can get pretty close using what’s called ambient micing.

Ambient Micing

So, let’s talk about ambient micing. This is simply using two or more microphones to pick up the sound of the room and then adding it to your live stream mix. These mics pick up the sound reflections and the response from the congregation. So, they help make it feel like you’re actually there. You can use pretty much any microphone for this, but I’ve found small diaphragm condensers with a cardioid pickup pattern to work best.

Mic Placement

For placement, I recommend putting a mic on each side of the stage, pointed towards the congregation. Place the mics a few feet behind your main speakers. This does a good job rejecting direct sound from your main speakers and gives you a good stereo mix of the room. When it comes to height, you can put them on stands at about ear level of those on the stage. This works best if you want your ambient mics to also double for your musicians in-ear monitors, which I recommend. A two for one is always a good deal. You can also hang them from the ceiling. You’ll just have to find the right balance between sound and aesthetics. Experimenting with different placements is the best way to figure that out.

Setup on Your Mixer

Now connect them to your mixer and link them together as a stereo pair. If you are unable to link them, simply pan one to the left and the other to the right in your live stream mix. Next, set the gain for these mics while the full band is playing and the room is full of sound. You set gain the same way for these as you do any other mic. I have a video on how to set gain if you need help with that. I’ll include a link in the description. Keep in mind, if you are using condenser mics, you’ll need to activate 48V phantom power. Finally add a low cut filter at about 300Hz because trust me, you don’t want the ambient low frequencies as part of your live stream mix. They make it sound like a big jumbled mess. And that’s it. Your ambient mics are now set up and ready to go.

Add Them to Your Mix

Simply add them to your live stream mix to bring it to life. The easiest way to do this is with the SENDS ON FADER control. Here’s how:

  2. Select your live stream bus
  3. Navigate to the Ambient mics and adjust the level in your live stream mix using the fader.

A good starting point is -10dB. Then adjust so that you hear what is going on in the room, but be careful not to turn them up too loud because then it just sounds echoey. Alright, one last tip: Make sure your ambient mics aren’t going to your room mix. Otherwise, you’re in for a fun battle with feedback.

Importance of the Room Mix

Ambient mics are going to make a huge difference! But keep in mind, the live stream mix is a reflection of what’s going on in your auditorium, so you’ll want to make sure your room mix is the best it can be.
