# Adjusting microphone gain setting for HDL300 systems

When using Nureva® HDL300 systems a microphone gain adjustment is available. This setting is available with the Nureva App and Nureva Console.

> [!NOTE]
> **Important:** The HDL300 system requires firmware version 2.2.56 (or later) for this feature to be available.

## Nureva App

The microphone volume gain is adjusted in individual increments—slide left to decrease gain and right to increase gain. The default (0 dB) setting is at the 1/3 point. Dragging the slider all the way to the left will reduce microphone gain by 6 dB. Dragging the slider all the way to the right will increase microphone gain by 12 dB.

1. Launch the Nureva App.
2. Open the **Settings** menu.
3. Expand the **Microphone** menu.
4. Adjust the **Mic gain** slider as needed.

When adjustments are complete, Nureva App can be closed. Your adjusted settings will automatically be saved.

## Nureva Console

The microphone volume gain is adjusted in individual increments—slide left to decrease gain and right to increase gain. The default (0 dB) setting is at the 1/3 point. Dragging the slider all the way to the left will reduce microphone gain by 6 dB. Dragging the slider all the way to the right will increase microphone gain by 12 dB.

1. Open Nureva Console.
2. Select the Nureva audio device to be adjusted.
3. Scroll down to **Settings** and open the menu.
4. Expand the **Microphone** menu.
5. Adjust the **Mic gain** slider as needed.

When adjustments are complete, click the **Apply** button and close Nureva Console.

## When to use it

This setting is intended for situations where the UC&C client is taking control of the microphone volume setting in the operating system and making the audio picked up by the Nureva system either too loud or too quiet for remote participants. This setting should only be used to address specific problems.
