You will use the Omnia XII front panel. ### Configuring Inputs For quick setup, use a valid analog or AES input source, which is plugged into the appropriate back-panel connectors. **To configure Omnia XII Analog or AES inputs:** 1. On the Omnia XII front panel, press the Omnia logo to reveal the front panel menus. ![](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/Screenshot 2026-08-28 at 8.50.11 AM.png?sv=2026-02-06&spr=https&st=2026-11-10T17%3A15%3A00Z&se=2026-11-10T18%3A15%3A00Z&sr=c&sp=r&sig=Br5Xa1doXhRgAMT1B6l5M%2FqgDuNl%2ByVJby9nkdfwhPM%3D) Omnia logo and front panel menus 2. Press the **Inputs** menu. 1. Drive the input for the preferred mix with typical program material at a normal operating level. You should see meter activity on the **IN** bar graph meters. 2. Press the **Preferred Mix** tab and set the fader level for the input you are using (**Analog**, **AES 1**, **AES 2**, or **AES 3)**. Refer to the horizontal **IN** meter at the top of the screen. ![](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%3A15%3A00Z&se=2026-11-10T18%3A15%3A00Z&sr=c&sp=r&sig=Br5Xa1doXhRgAMT1B6l5M%2FqgDuNl%2ByVJby9nkdfwhPM%3D) Preferred Mix controls 1. Adjust the input level so that the peak-reading **IN** bar graph meters read just into the yellow (about -15 to -12 dBFS). > [!NOTE] > **Note:** The IN bar graph meters are post-fader. The individual input level meters (Analog, AES 1, and so on) are pre-fader. 2. Set all faders that are not part of the **Preferred Mix** to **OFF**. ### Configuring Composite MPX Outputs Composite MPX output is via the Omnia XII back-panel **1 Out** or **2 Out** stereo BNC connector in the **Composite I/O** section. **To configure Omnia XII composite MPX output:** 1. Play typical program material through the Omnia XII. 2. Press the Omnia logo to reveal the front panel menus, and then press the **MPX** menu. 3. On the MPX outputs page, press the **FM Options** tab and ensure that the **Pre-emphasis** setting is correct for your country. ![](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/FM Options(1).png?sv=2026-02-06&spr=https&st=2026-11-10T17%3A15%3A00Z&se=2026-11-10T18%3A15%3A00Z&sr=c&sp=r&sig=Br5Xa1doXhRgAMT1B6l5M%2FqgDuNl%2ByVJby9nkdfwhPM%3D) MPX FM options 4. Press the **Back Panel** tab and ensure that the **Function** setting for the composite output to be used is set to MPX, and then set the composite output level using the appropriate **Level** control. ![](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/Back Panel.png?sv=2026-02-06&spr=https&st=2026-11-10T17%3A15%3A00Z&se=2026-11-10T18%3A15%3A00Z&sr=c&sp=r&sig=Br5Xa1doXhRgAMT1B6l5M%2FqgDuNl%2ByVJby9nkdfwhPM%3D) MPX Composite Back Panel controls 5. Verify that normal program material is present and that the configured outputs indicate audio on the MPX output meters. ## Selecting a Preset Omnia XII ships with **ADULT_HITS** loaded as its factory default preset. **ADULT_HITS** is a great, general purpose preset that will get you started. Experiment loading other factory presets to match your programming. See *Working with Presets* in the *Omnia XII User Manual* for information about auditioning and selecting presets. Once the output meters show normal program material and the selected preset is running, see the *Omnia XII User Manual* for further processing, I/O, RDS, AoIP, failover, Playout, and system configuration.
