Making Expanded Processing Changes

The web UI provides access to a full set of Expanded processing controls for making detailed adjustments.

When the PROC tab and Expanded button are selected, the middle section of the PROC page displays a block diagram of the processing path your audio takes through the fully digital, DSP-based processing stages within the Omnia XII. Each block within the diagram is a selectable item that provides access to its respective Expanded controls.

The audio starts at the Initial section, where pre-processing, wideband automatic gain control, and Dynamic EQ are configured. The audio then passes through the MB AGC/Comp (five-band multi-band AGC/compressor), the MB Limiter (six-band multi-band limiter), Watermarking (when used), and the final Backend block, which provides separate peak-control sections for FM and HD channels.

Tip! Some Expanded control panels contain more controls than can be displayed at once. When available, use the scroll bar to view additional controls. Some blocks also provide Primary and Advanced buttons for accessing separate sets of controls. Additionally, there can be filter icons that let you hide an item or set of items.

Expanded controls are not available from the front panel touchscreen.

Adjusting a Preset with Expanded Controls

After selecting a preset, you can use Expanded controls to customize it.

To access Expanded controls:

1. Launch the web UI.

2. Click FM / HD Processing.

3. In the header, make sure the PROC tab is enabled.

   This displays the PROC page, which includes the Expanded button in the middle panel.

4. Click Expanded.

   

   The Expanded block diagram displays in the middle panel.

5. In the block diagram, click the block item you want to adjust to display its sub-items.

   

   

   Note: The Watermarking block does not have sub-items. It immediately displays its controls. See Using a Watermark Encoder.

6. Click the desired sub-item block to display its controls in the bottom of the page.

   

To adjust a control in the Expanded panel:

• To change a drop-down menu setting, click the drop-down menu and click on the desired setting.

• To change a switch setting (such as an ON/OFF switch), click the switch to toggle it on or off.

• To change a value with a mouse, click and drag within the control area, and move the mouse to the right to increase a value, or to the left to decrease a value.

• To change a value by typing in a value, click in the value field for a control, press Delete to erase the current value, type in a new value, and then press Enter.

After adjusting a control, the Current Preset label in the middle panel header changes to Modified Preset.

To save changes as a user preset, see Working with Presets.

Navigating Expanded Controls

For each block that has Expanded controls, the controls display in the bottom panel of the web UI.

Some blocks provide Primary and Advanced buttons for accessing separate sets of controls. Additionally, there can be filter icons that let you hide an item or set of items.

Some Expanded blocks (such as Dynamic EQ and Watermarking) provide all of the available controls in a single panel. These blocks do not have Primary and Advanced buttons.

Example: Selecting different levels of Expanded controls

1. Access the Expanded controls.

2. In the middle panel, click the Initial block to display the preset’s Pre-proc, WBAGC, and Dynamic EQ processing blocks.

   

   

3. Click the WBAGC (Wideband Automatic Gain Control) block, and then click the Primary button to display the WBAGC primary controls.

   

4. Click the Ratios filter icon to hide the Ratio control.

   

5. Click Advanced to display the WBAGC advanced controls.

   

Basic Overview of Using Expanded Controls

When making adjustments with Expanded controls:

• Start with a factory preset or a user preset that is already close to the desired sound.

• Before making adjustments, have a specific objective in mind, such as changing loudness, frequency balance, or the overall sound character.

• Make a small num bar of changes at a time, using small increments appropriate to each control.

• Listen to the results over time before making additional adjustments. Avoid evaluating a change immediately after making it.

• If the results are not satisfactory, recall the original preset and start again. Factory presets cannot be overwritten.
