The X-One internal audio mixer interface appears on your secondary screen when you tap or click the tab in the vertical menu.
It allows you to control the level and gain of individual audio inputs from the live camera feeds and clips and to route them so that they are played out with the appropriate clips. You can also control the levels of the audio outputs.
The X-One audio mixer supports the ingest of 12 audio channels, i.e. 2 audio channels per SDI feed from each live camera, by means of 6 audio embedders. The audio outputs are embedded to the first 4 embedded audios of the PGM SDI output.
The main areas of the Audio Mixer interface are indicated on the screenshot below:
This area displays the first embedded stereo pair of each live camera feed. It allows you to control the gain and level of each audio input.
This area displays the audio tracks of (imported) clip(s) or live feeds for the camera loaded on the PGM channel. It allows you to control the gain and level of each audio track.
This area displays the 4 audio outputs: the Main Mix (left and right) and the Auxiliary Mix (left and right). It allows you to control the levels of the outputs and to link/unlink the stereo pairs.
This area enables you to create an audio preset or edit an existing one. See section "Audio Presets".
In some cases, the audio input signals are not the best quality. The Audio Mixer allows you to increase or decrease the gain value.
To increase or decrease the gain value, click or tap the gain control and move the dial clockwise or counter-clockwise.
By default the gain is set to 0 dB. The range value is -20 to +30 dB.
During a production, the audio level of the source can change.
In this case, you need to be able to decrease or increase the audio level of each audio input independently in order to keep the mixed output consistent throughout the production.
To increase or decrease the level of an audio input, drag the corresponding fader up or down.
By default the audio level is set to 0 dB. The range value is minus infinity to +10 dB.
Not all audio inputs are used all the time during a production. For example, the journalist's microphone is used exclusively during interviews. For the rest of the production, it is important to remove this microphone from the Main Mix.
In these cases, you can mute each audio input independently.
Tap the Mute button to mute an audio input.
The audio level will be set to minus infinity dB and the audio level bar will be grayed out.
Tap the Mute button again to unmute a muted audio input.
The previous audio level is restored.
X-One outputs two stereo pairs (Main Mix & Auxiliary Mix) on the PGM that consist of a mix of 14 input audio tracks (2 per live camera feed + 2 for A/V files).
The audio outputs are embedded in the first 4 embedded audios of the PGM SDI output.
To route an audio input to the appropriate audio output (Main Mix Left/Right; Aux Mix Left/Right), tap the corresponding button.
|•||Main Mix L1 or Auxiliary Mix L2 if the audio input is a left audio source.|
|•||Main Mix R1 or Auxiliary Mix R2 if the audio input is a right audio source.|
|•||Main Mix L1 & R1 or Auxiliary Mix L2 & R2 if the audio input is a mono source, e.g. a microphone.|
To mute and unmute an audio output, tap the Mute button in the same way as for an audio input.
To change the level of an audio output, drag the corresponding fader up or down in the same way as for an audio input.
To quickly change the levels of both audio tracks of the Main Mix or of the Auxiliary Mix, click the Link button.
If you now move one of the faders up or down, the other will move up and down as well.
Audio presets are 'snapshots' of different audio levels. You can use audio presets to specify in advance the audio channels which will be played out when any content is sent on air. Presets can therefore be associated with cameras, types of media or clips, as well as the PGM playout. It is possible to create up to 50 audio presets.
Presets can be created in advance of your production and are stored in the library. It is also possible to save audio presets in the ShotBox. They can then be assigned manually to any content type when it is sent on air. The changeover from one audio preset to another is achieved with a logarithmic cross-fade (fade out-fade in). It is possible to edit prests during a production.
Audio presets can also be used to configure audio templates, so that the same audio settings will be automatically applied when a certain type of content is played out. See section "Creating Audio Templates".
|1.||Click or tap the Audio button to open the audio tab in the live Settings menu on the secondary screen.|
|2.||Click or tap on the Create Preset button in the lower left corner of the screen.|
|3.||Adjust or mute the levels as required for the audio channels, media outputs and general output. When the levels are changed from their initial values, the channel's corresponding bar changes from blue to orange.|
|4.||Enter a name for the preset in the field on the right and click or tap on Save.|
|1.||To play out an audio preset, click or tap the red or green side of the Audio Preset element in the library or ShotBox.|
The specified audio channels in the preset will be applied and played out with the media loaded in the PGM or PRV respectively.
|2.||To stop using the preset and return to the default audio configuration in the PGM or PRV, click on the red or green cross displayed on the preset element in the library or ShotBox.|
|1.||Open the Audio tab in the live Settings menu on the secondary screen.|
|2.||Select the audio preset you want to edit from the list.|
The audio preset is displayed in the internal mixer window, where the audio channel levels can be adjusted.
|3.||Click or press Cancel to discard any changes, or Save to update the preset.|
You can also change the name, then click or tap on Save to create a new preset based on the original one.
|4.||If the name is not changed, the following dialog box will ask you to update the existing preset or create a new one.|
|1.||To delete an Audio Preset element in the Library, click or tap the element and click or tap on Delete in the lower right corner of the window.|
As with all library elements, it is also possible to delete several elements at the same time by selecting their checkboxes to the left.
The following popup message will ask you to validate the deletion. Click on Yes, Delete to confirm.
The Monitoring tab window displays the audio output of clips or live feeds that have been loaded in the PRV channel. Using a headset connected to the mini-jack socket of the sound board, it is possible to monitor and control the audio output level.
|2.||Load a clip in the PRV channel and tap or click the Play button.|
|3.||Click or tap the tab button in the vertical menu to open the monitoring tab window.|
|4.||Click or tap the appropriate left and right audio buttons to load them in the PRV audio output.|
