# Front Panel Touchscreen

The Omnia XII front-panel touchscreen provides controls, and metering for configuring and operating Omnia XII. Some functions, including input, output, and composite MPX configuration, can also be accessed remotely through the Omnia XII web UI.

Omnia XII Home screen

## Inputs Menu

This menu provides controls for assigning and configuring audio sources, including the **Preferred Mix**, **Fallback Mix**, **Failover**, and **Patch Return**.

> [!NOTE]
> **Note:** Most Input controls are also accessible through the Omnia XII web UI. The touchscreen Inputs menu does not provide the web UI’s AoIP, HLS+, or Playout pages.

### Inputs Page

This page provides controls for input paths that receive audio from physical inputs or internal sources. The selected input feeds the Omnia XII processing chain, which then drives the configured outputs.

![](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/Inputs Page.png?sv=2026-02-06&spr=https&st=2026-11-10T17%3A37%3A06Z&se=2026-11-10T18%3A37%3A06Z&sr=c&sp=r&sig=XUwYdzScIws9ZOIbguBoIhrfOErhN55x7g9rR68Bcvk%3D)

Inputs controls

Internal input paths include:

- **Analog:** Audio fed from the back-panel **Analog Left** and **Analog Righ**t inputs
- **AES 1**, **AES 2 and AES 3:** Audio fed from the respective back panel **AES** inputs
- **AoIP 1 and AoIP 2:** Audio received from configured Livewire+/AES67 network stream, via back-panel **NET 1**.
- **Playout:** Audio (such as emergency audio, backup audio), fed from internal playout location.
- **HLS+ (HTTP Live Streaming):** Audio fed via the Omnia XII Ethernet.

Each path provides these controls:

- **Invert L**: Inverts the left channel signal. Default is **OFF**.
- **Invert R**: Inverts the right channel signal. Default is **OFF**.
- **Stereo Mode:** Selects the desired mode (**Stereo** , **Mono L**, **Mono R**, **Mono** **Sum**, **Swap**, or **M**t**x**). The default is **Stereo**.
- **Right Trim:** Lets you adjust the right channel so that it matches the left channel, from -20 to 20 dB. Default is 0 dB.

### Preferred Mix Page

This page lets you configure the back-panel connection that supports your primary audio sources. This is your main input source.

![](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/Preferred Mix(3).png?sv=2026-02-06&spr=https&st=2026-11-10T17%3A37%3A06Z&se=2026-11-10T18%3A37%3A06Z&sr=c&sp=r&sig=XUwYdzScIws9ZOIbguBoIhrfOErhN55x7g9rR68Bcvk%3D)

Preferred Mix controls

This page includes the same input paths as the **Input** page.

Each path provides these controls

- **Level:** Sets the input level of the back-panel connection that is participating in the **Preferred Mix** (so that the peak-reading **IN** bar graph meters read just into the yellow, about -15 to -12 dBFS). Faders that are not part of the **Preferred Mix** should be set to **OFF**. The default is 0 dB.
- **Fade Time:** Sets the fade time of the back-panel connection participating in the mix. 0 to 10 seconds, in .5 second steps. Default is 0 seconds.

### Fallback Mix Page

This page lets you configure the back-panel connection that supports your backup audio sources. This is your secondary input source.

![](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/Fallback Mix.png?sv=2026-02-06&spr=https&st=2026-11-10T17%3A37%3A06Z&se=2026-11-10T18%3A37%3A06Z&sr=c&sp=r&sig=XUwYdzScIws9ZOIbguBoIhrfOErhN55x7g9rR68Bcvk%3D)

Fallback Mix controls

This page includes the same input paths as the **Input** page.

Each path provides these controls

- **Level:** Sets the input level of the back-panel connection that is participating in the **Fallback Mix** (so that the peak-reading **IN** bar graph meters read just into the yellow, about -15 to -12 dBFS). Faders that are not part of the **Fallback Mix** should be set to **OFF**. The default is 0 dB.
- **Fade Time:** Sets the fade time of the back-panel connection participating in the mix. 0 to 10 seconds, in .5 second steps. Default is 0 seconds.

### Failover Page

This page provides controls for configuring how the Omnia XII switches to your backup system audio (fallback mix) when the preferred mix is not detected.

![](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/Failover Page.png?sv=2026-02-06&spr=https&st=2026-11-10T17%3A37%3A06Z&se=2026-11-10T18%3A37%3A06Z&sr=c&sp=r&sig=XUwYdzScIws9ZOIbguBoIhrfOErhN55x7g9rR68Bcvk%3D)

Failover controls

**Input Mode:** Sets which mix is used when a failover occurs.

- **Preferred Only:** When a failover occurs, the **Preferred Mix** remains in use. This is the default Input mode.
- **Fallback Only:** When a failover occurs, the **Fallback Mix** remains in use.
- **Failover:** When a failover occurs, the system switches from the **Preferred Mix** to the **Fallback Mix.**

**Trigger Time:** Sets the amount of time that will elapse after the failure of audio on the preferred mix before the unit switches to the fallback mix. For instance, if time is set for 5 seconds and the primary audio source fails, five seconds later the unit will switch to the secondary audio input if that input is active. The range is 1 to 30 seconds, in .25 second steps

**Return Time:** Sets the amount of time for the fallback mix to continue after the preferred mix is restored and the unit switches back to the preferred mix. The range is 0 to 10 seconds, in .1 second steps

**Detect Level:** Sets the absolute silence threshold in dB for the main silence detector. Audio falling below this level is treated as dead air. The range is -70 to 0 dB in 1 dB steps.

**Detect Relative Level:** Controls the differential threshold between your operational audio channel levels. It protects against stereo balance and phase protection or side-channel integrity failover. The range is -60 to 0 dB, in 1 dB steps.

### Patch Return Page

This page provides controls for use of a patch return for watermarking.

![](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/Patch return.png?sv=2026-02-06&spr=https&st=2026-11-10T17%3A37%3A06Z&se=2026-11-10T18%3A37%3A06Z&sr=c&sp=r&sig=XUwYdzScIws9ZOIbguBoIhrfOErhN55x7g9rR68Bcvk%3D)

Patch Return controls

**Patch Mode:** Enables or disables the use of the patch return for watermarking. The Patch Return acts as a physical or virtual loop insert point. It sits between the output of the bass clipper (after the MB limiters) and the backend (that is, the FM clipper). The patch point lets you insert external compliance equipment or local hardware into the feed without disrupting your upstream failover configuration. Default is OFF.

**Patch Return Source:** Sets the patch point source/destination to the exact physical output port where you plugged in the Voltair input cable (for example AES 1). Default is AES 1.

**Patch Gain:** Sets the level of the patch point. Range is -20 to 20 dB, in .5 dB steps. Default is 0 dB.

## Outputs Menu

This menu provides controls to assign audio sources to the Omnia XII output connections and configure the settings for each output in use. Output connections include the back-panel analog and AES outputs, front-panel headphone output, and AoIP outputs.

> [!NOTE]
> **Note:** Most Outputs controls are also accessible through the Omnia XII web UI. The touchscreen Outputs menu does not provide the web UI’s Program Delay and AoIP Senders pages

- **Level**: Sets the output level of the back-panel output connection or front panel headphone connection.
- **Right Trim:** Lets you adjust the right channel so that it matches the left channel, from -20 to 20 dB. Default is 0 dB.
