Using External Devices on Modern macOS Devices Certain audio input devices may also come with their own control software, allowing you to further calibrate your input settings.
You may also have additional controls and settings available to you, depending on the type of device you’re using. You’ll be able to see the current volume value (listed in decibels), as well as the input volume (a decimal figure, up to a maximum of 1) next to the Master volume slide for your device.
