Introduction, user experience, and behavior

To use the TVU Producer Audio Mixer requires a Producer subscription activation from TVU Support. Before you begin, refer to the TVU Producer System requirements below, then contact TVU Support to obtain your login credentials. TVU Networks recommends logging in to your TVU Producer account using your credentials and familiarizing yourself with the user interface, features, and functions.

TVU Producer Audio Mixer overview

The Audio Mixer is a dedicated interface embedded into the TVU Producer user interface. The Audio Mixer feature is built for audio operators to mix audio for the TVU Producer program separately from the video and graphics operations.

The Audio Mixer interface opens in a separate tab, allowing the individual operator to adjust the volume. The basic functions include adjusting each input source’s volume or fader level and mixing selected audio sources.

The Advanced Audio Mixer Panel allows a Producer user to manage all input levels and master output, complemented with remote commentary in real time. Advanced capabilities serve multiple collaborators or users working to produce a single live show. The operator primarily focuses on using all the advanced capabilities provided in the audio mixer.

Audio Mixer features

Audio Mixer enables the operator to perform the following advanced operations:

• Automatic Gain Control (AGC) supports the master mix and all source types.
• Streamdeck support.
• MIDI support for multi-channel sources and source on/off controls.
• Monitor each video and audio feed for production.
• Adjust all audio input levels as well as the master output
• Adjust pans (audio gain) for each channel.
• Mute each channel.
• Assign channels for each group for simple management of multiple sources.
• Allows Audio Follow Video (AFV) by source for all pairs in a multi-channel source.
• Allows AFV for Custom Sources.
• Link faders across output pairs.

Note: Refer to “Advanced Audio Mixer user experience behavior” for information about stereo and dual mono settings.

5. Adjust the individual source audio settings for channel 1, then adjust the Master audio level in the left panel to the desired setting.
6. Click channel setting 2 and repeat steps 4 and 5, respectively, and so on, to pair up to 4 channels (with a maximum of 8 outputs).
7. To adjust your audio channel paired settings, click the appropriate Audio Output Pair Control channel number to display your settings.

Advanced Audio Mixer user experience behavior

The following two types of audio sources are supported in the Advanced Audio Mixer interface:

Stereo: Stereo has one channel and includes one fader, pan control, and audio level indicators. When stereo is selected, both left and right indicators illuminate together to indicate one channel.

Dual mono: Dual mono has a left and right channel and includes two fader controls, two pan controls, and two audio level indicators. When dual mono is selected, both left and right indicators illuminate separately to indicate two channels.

The “Stereo and Dual-mono channel examples” figure shows the Stereo and dual mono channels:

• Source 1 indicates Stereo (one channel)
• Source 2 shows Dual mono (left and right channels)

The Fader level indicator ranges from -∞ to +12

Note: The following stereo and dual-mono channel example is shown to highlight the differences.

Audio usage indicators are displayed in red at the bottom of the panel.

Stereo audio source

The Stereo audio source has only one fader and one balance control (or Pan control), as shown below.

• The fader level indicator range is from -∞ to +12.
• Balance control ranges from 0 to 100. The balance is set to 50 (middle).

Dual-mono audio source

The Dual-mono audio source has two faders and two pan controls. One fader controls the left channel, and the other controls the right channel. The two channels operate independently.

• Each channel has an independent fader level indicator ranging from -∞ to +12.
• The pan control slide ranges from 0 to 100. The left pan control setting is 0, and the right pan control setting is 100.

Note: Dual Mono mode does not support MIDI devices. A warning message will display allowing you to convert to Dual Mono. Switching the source to stereo will support MIDI devices.

Headphone control and sound monitoring

The headphone icon allows the operator to monitor a specific audio channel.

Fader level control

The fader level indicators show the appropriate status from the basic mixer. When the Audio Mixer displays for the first time, the fader level indicators must be set to the appropriate volume or gain, even though sound monitoring is switched.

This will provide the audio operator with real-time results, ensuring all audio channel volumes are correctly working. The operator can then adjust the gains of specific audio channels as desired.

Audio usage indicator and enable/disable functions

The audio usage and enable/disable indicator button at the top of the panel (turns red or grey).

The Audio usage button (one for each channel in the input source) indicates which audio channels are used or enabled.

• When the audio switch is ON or enabled, it turns red
• When the audio switch is OFF or disabled, it turns grey

When live sources are switched, the audio usage indicator (in red) is applied to the newly switched input source and the channels. If PIP is enabled on a live source, then both these input sources, which are going to program output, will indicate usage when their left and right channel indicators turn red.

Note: If AFV is enabled, the audio usage is read-only. The operator cannot enable audio on more than one channel.

Note: If AFV is disabled, the operator can click on the audio usage button to switch between grey (disabled) to red (enabled) or red (enabled) to grey (disabled).

If the operator changes the audio usage on two different channels to Red, those two audio channels will go to program output.

Audio control for quad mode

When the quad mode (input source 7) is selected, it behaves like any other source.

The audio usage indicator is ON for source 7 (and is only lit up for source 7), and whatever the presetting was for its original source still applies.

Monitor level control

The Monitor level control in the audio mixer controls the volume of the Audio Mixer tab in the Chrome browser.

Mute control

The Mute control allows the end-user to silence the audio channel completely. This will also silence the channel output audio.

Note: Mute can be used in both use-cases, when AFV is ON or OFF.

The user can mute the stereo source or dual-mono source channels when AFV is ON. When the mute icon is switched ON for the ‘Source’ chosen to go to Program output, the master volume is also muted.

In the following example, AFV is enabled. Video source 6 is chosen to go to the program output. When both channels are muted for this specific audio source, the master volume is entirely muted on the program output. Group audio is not enabled in the following ‘Use-case example.’

Mute functionality works similarly if AFV is OFF and the Group Audio feature is enabled.

In the use-case example, the user can use the mute functionality associated with the group directly. When using the mute icon associated with Group 1 or Group 2, the user can mute all of the audio sources assigned to Group 1 or Group 2.

The user can also mute one of the audio channels chosen for Group 1, which will silence only that specific channel.

Group Audio feature

The Group Audio functionality is enabled only when AFV is OFF. Users cannot choose groups in AFV mode.

The Group Audio feature enables users to assign audio channels to specific groups. The Audio Mixer Panel supports two groups.

To use the Group Audio feature:

1. Open the Advanced Audio Mixer panel.
2. Assign each desired audio channel in each respective audio source (whether a stereo source or dual mono) to group 1 or 2.
3. Choose the desired channels and assign them to either group 1 or 2.

Note: Selecting audio channels for specific groups can be completed initially without enabling the group audio functionality.

4. To change the Group Audio setting, select Group 1 or 2 in the program output panel, then click the ON button in the Audio panel above Group Audio.

Note: Users can switch either group or both groups simultaneously to manage and control all of the audio channels and sources associated with a specific group.

5. If desired, a user can dynamically assign new channels to either of the groups.

Note: The ‘ON” Audio Button can be enabled only after assigning at least one audio channel. If the user has not assigned any audio sources to either group, the user cannot switch ON the group audio.

In the following ‘Channel and input source example,’ channel 2 of input source 1 is assigned to Group 2. In addition, the two audio channels of the input source 3 are also assigned to Group 2. The User interface will now allow the user to switch ON the Group 2 control, then reduce the fader levels of all the associated channels using the Group fader controls.

Note: Enabling the group feature will not have any impact on the current master volume functionality.
