# Tuning beams in Control This section demonstrates how to adjust beams in the currently active preset and modify the system-level EQ in HOLOPLOT Control. The Tuning section's Main EQ, Function Groups and Beam Tuning tabs enable further sound personalization in real-time, offering more control over low frequencies. ## Main EQ It includes six bands to adjust the system-level EQ.

## Function Groups EQ

OS 2.5 introduces Function Groups, allowing you to tune beams according to their role within a [Preset Layer](#user-content-fn-1)[^1]. Function Group tuning covers six bands for EQ adjustment. There are two ways of adjusting the EQ of a Function Group: * Using the Function Group tab (recommended for taste EQ adjustments). * Through the Beam Tuning tab. In this case, for the Function Group to appear, the beams in the table must be grouped by `Preset Layer.` ## Beam tuning

The Beam Tuning page lets you adjust the EQ, gain, and delay of the beams, either individually or in bulk, for the currently selected preset and its associated environmental conditions. The Beam Tuning tab is divided into two panels: #### **1. Beam table – left panel**

The table displays all the beams belonging to the active preset with the following information or actions: * Gain and delay values broken into: * Automatically defined values are set in HOLOPLOT internal tools (these values are only accessible for project files created internally at HOLOPLOT). * User-defined values in HOLOPLOT Control's **Tuning** section. These fields are editable. * Total values are the sum of the automatically and user-defined values. * Mute and Solo buttons. * A signal indicator is used to verify whether a signal is present. * EQ button to activate or bypass the EQ when previously set. {% hint style="info" %} A beam's tuning is linked to the preset layer and environmental conditions. This means each beam will have different gain, delay, and EQ values for each associated preset layer. Any change made to a beam will automatically impact all of its environmental conditions. If you need to change this, uncheck the 'Apply to all environmental conditions' box located in the top-right corner of the panel and manually select the environmental conditions using the Beam Selector. {% endhint %} **Batch Actions** The following batch actions are available for all beams: * Mute/Solo * EQs: bypass and copying/pasting them. * Gain: relative and absolute gain adjustment. * Delay: relative and absolute delay adjustment. #### **2. Beam EQ – right panel**

This panel displays the EQ window for the selected beam on the left, featuring eight bands. It also shows the beam input level meter and the connected arrays to monitor output levels. When the **Sum EQ** checkbox is enabled, the displayed EQ curve represents the combined (summed) response of the Function Group EQ, the Main EQ, and the Beam EQ. When the checkbox is disabled, the EQ curve displayed corresponds only to the Beam EQ, with no contribution from the Function Group or Main EQ processing. | Show Sum EQs | Hide Sum EQs | | ------------------------------------------------------------------- | ------------------------------------------------------------------- | |

| ### Applying tuning values to other beams

#### Copy and paste a beam's EQ values OS 2.5 allows copying and pasting EQs between beams. You can use the copy/paste buttons on the beam EQ panel or the multi-select option on the beam table to batch-edit the EQs of selected beams. #### Apply EQs to beams in different presets To apply the current beam's settings to a beam in the same or different preset, click the menu in the top-right corner of the beam EQ panel and select "Apply EQ with Beam Selector." A dialog box with a list of DSP settings, beams, and environmental conditions will appear. Choose the beams you want to apply the settings to and click "Apply."

#### Export and import a beam's EQ values While tuning the system, you can export a beam's EQ values and apply them to other beams. * To export the EQ, click the menu in the top-right corner of the beam EQ panel and select "Export EQ." A \`.json\` file will be downloaded immediately. * To import the EQ, go to the beam you want to apply it to, click the menu at the top-right corner of the beam EQ panel, and select Import EQ. Select the previously saved \`.json\` file and confirm the action.

*** ## Analog beam tuning After setting up Analog Mode, go to the **Tuning** section and select the **Analog Tuning** tab to adjust the analog beams. The presets, audio inputs and modes related to analog are highlighted in blue. {% hint style="info" %} Find out more information about Analog Mode in [Setting up Analog mode on X2 Modules](/holoplot-control/configuring-the-system/setting-up-analog-mode-on-x2-modules.md) {% endhint %}
