Configuring Audio in Livestream Studio

With all three Mevo cameras recognized by Livestream Studio, the next step is to make sure your microphone and audio mixer are both recognized and configured properly to ensure high-quality audio.

Check Settings for the Blackjack Onyx Mixer

Livestream Studio’s built-in audio mixer can be found by clicking the Audio Mixer tab in the lower left corner of the interface.

Each source, including your cameras and any elements you add later (video clips, graphics, etc.) will have a corresponding audio source that you can monitor and adjust.

Click the gearwheel button in the upper right corner of Livestream Studio to enter the Settings menu.

 

 

Navigate to the Audio In tab, then press the button at the bottom of the window to add an audio source.

Click the dropdown menu under Audio Source to select the Blackjack Onyx audio mixer.

If the Blackjack Onyx audio mixer appears to already be selected but shows (Inactive) in its name, reselect it from the dropdown menu. This should activate it in Livestream Studio.

Your audio mixer will be given a default name, such as "AUDIO1." If you wish to have it referred to as something else, click the name and type in a new name for it.

Click Save in settings. You should now see your audio source included with your other sources in the Audio Mixer.

Configure Livestream Studio's Audio Mixer

With the Blackjack Onyx mixer added to Livestream Studio, the next step is to make sure sound is getting from the wireless microphone into Livestream Studio.

First, check the input on the Blackjack Onyx mixer into which you plugged the XLR cable from the wireless audio receiver (in this example, Input 1). Turn the audio gain knob that corresponds with that input clockwise; we recommend selecting the 30-40 range.

Test the microphone by speaking into it, tapping it, or otherwise sending noise into it. Audio levels appear on the wireless receiver's display, and the LED in the Blackjack Onyx mixer flashes when it detects sound. This means that the microphone, the wireless receiver, and the mixer are all functioning normally.

 

Continue to test your microphone this way and check Livestream Studio. Under the Audio Mixer tab, navigate to your AUDIO1 source. Green and yellow levels also appear here, indicating that your microphone's audio is reaching Livestream Studio. The more yellow levels appear and the higher they go, the louder your audio is.

To adjust the levels of AUDIO1 or any audio source, click and drag the corresponding fader.

If audio levels are too high, the mixer's OVR meter for any over-modulating source will blink red. Lower your audio in either Livestream Studio or the Blackjack Onyx mixer to maintain ideal levels.

If you want to hear your microphone's audio in both audio channels, navigate to the Input Settings tab.

Select the Audio tab on the left side.

Your microphone's audio may only be coming in through one channel on one input. In this example, audio is coming in through Input 1, but only through the left channel. Click R to enable the right channel.

If you wish to plug in a second audio source, such as a music source or another microphone, you can simply repeat these steps using Input 2.

As an additional best practice, navigate to the Delay menu under the Input Settings module.

Because the Blackjack Onyx is directly connected to the PC, whereas your cameras are connected over a LAN, it's possible you may experience audio and video being out of sync. The Delay menu will allow you to delay your audio coming into Livestream Studio by as many as two seconds, in addition to the one second of delay configured in the "Launch & Configure Livestream Studio" section of this manual.

 

Livestream's testing has shown that adding 100 milliseconds of delay by clicking the +100 button on the far right of the scale will typically resolve most sync issues.

As a best practice, always test for audio/video sync before your event begins by having someone speak into the microphone while looking at the camera while another person listens via the headphones and watches in the Livestream Studio multi-view.

Go back to the Audio Mixer tab. Audio levels are now coming into AUDIO1 on both channels.

With the kit's included equipment, the best practice is to link all three of your Mevo cameras to the Blackjack Onyx mixer to allow for seamless transitioning between the three cameras while maintaining consistent audio.

 

Click one of your Remote Cam sources within the Audio Mixer. You will notice you have the option to link to any other input source. Select Link to AUDIO1.

The mixer will indicate which source’s audio is being output to that camera. Note that REMOTE1 and AUDIO1 now have identical audio levels.

Do the same with the other two remote camera sources. All three should read AUDIO1 underneath each and be showing identical audio levels.

Monitoring Audio Through Headphones

In live video production, monitoring your audio is essential to ensuring your event goes off without a hitch. This is why noise-isolating headphones are included with your kit.

To hear audio in your headphones, go to the Audio Mixer and navigate to the STREAM OUT monitor on the right side of the mixer. Click the headphone button that corresponds with it, which will prompt a light gray border to appear around the button. This will send that source's audio to your headphones without impacting its output to your stream and recording.

Next, check that you have set your volume level in the headphones slider bar at the top right corner of the Studio interface.

If you are still not hearing audio in your headphone or monitoring speakers, minimize your Studio interface; in Windows, click the speaker icon in the bottom right corner to reveal sound options. It's possible the Onyx Blackjack mixer overrode the headphones as an audio output.

If you see this, click on Line (Onyx Blackjack) to reveal more playback device options. Select Headphones.

Once the headphones are enabled as the playback device, make sure the Windows volume is set at a desired level.

In addition, adjust the volume knob on the left side of the headphones to the desired volume level.
