Note: This guide only applies to the Version 2 StudioOne using the "Audio Codec Card" device
All editions of the Studio One hardware include two 1/4" audio inputs and two 1/4" audio outputs. These can all be found labeled on the back of the unit.
To ensure that your Studio One audio setup is configured for your use case, go to Control Panel, and open Sound settings. You will want to ensure the following:
- Under the Playback tab, set Speakers: Realtek High Definition Audio as the Default Device. This will allow for the headphone jack in the front of the unit to work so that you can monitor audio from Studio.
- Also, under the Playback tab, set USB AUDIO CODEC as the Default Communication Device to allow the ¼” output jacks of the Studio One unit to stream out the Program Output of the Studio program at all times.
- Under the Recording tab, set Line: USB AUDIO CODEC as the default device to bring your ¼" audio inputs into Studio.
- Under the Recording tab, with Line: USB AUDIO CODEC selected, click “Properties” button, and make sure the “Listen to this device” option is checked.
Connecting audio devices through the ¼” audio outputs/inputs.
The 1/4" Line-Out plugs will output Program audio (i.e. audio coming through Stream Out/Record Out in Studio's audio mixer). Keep in mind these outputs are stereo by design.
When both outputs are used, the audio signal will be separated as L channel on one output and R channel on the other output, so you will hear Channel 1 through the L output and Channel 2 through the R output.
- Using ¼” TS – 1/8” TRS or ¼” TS – ¼” TS stereo cable with L Out OR R Out will give you stereo signal. Both channels L and R are sending out when a single stereo TS jack is connected to either L or R output.
- Using ¼” TS – 1/8” TRS or ¼” TS – ¼” TS mono or mono-stereo cable with L Out AND R Out will separate the signal to one channel to L Out and the other channel on R Out. The channels L and R are separated when both L and R outputs are used.
The input channels are separated by default as left channel to L In and right channel to R In. Plug in your audio source to the inputs (bottom ports). After you launch Studio, go to the Inputs tab in the lower right corner. Select Add Input > Audio Only. Select the USB AUDIO CODEC Input(s).
The source will automatically be labeled Audio 1 and appear in both the Inputs list and the Audio Mixer.
You can adjust the channel input into Studio by navigating to the Inputs tab, selecting the gear wheel that corresponds to Audio 1, and then selecting Audio on the left side.
You will see both audio channels; Input 1 is the Left (L) input, Input 2 is the Right (R) input. Each input can be configured to send audio out to either one channel or both channels.
For example, if your audio source is only plugged into the R input on the Studio One unit, you may want to configure Input 2 to send audio to both the L and R channels so that your viewers will hear audio from both sides rather than only one channel.
Both channels will be reflected inside Studio's Audio Mixer.
If you are using both 1/4" inputs, you can keep each input separate by selecting L under Input 1 and R under Input 2, creating a stereo audio output to your stream.
Monitoring the stream out sound.
As the system is using two (2) different audio chipsets, one through the audio board for Line-In/Line-Out inputs/outputs and Realtek audio chipset through the motherboard, when you start Livestream Studio software, the Audio Codec will be selected by default, so there are several options for monitoring the sound:
- From Front Audio jack output (headphones) when a mixer or inputs/outputs are not used, disable the USB AUDIO CODEC in Sound Control Panel. This way the Studio will automatically switch the sound output through Realtek High Definition Audio.
- Without disabling the USB AUDIO CODEC in Sound Control Panel, you can monitor the stream out sound through one of the two ¼” outputs from the back, using a ¼” to 1/8” adapter for headphone.
- Monitoring the stream out sound through a mixer (necessary to bring microphone inputs into Studio).
