This article describes the Audio Settings for devices running firmware version 7.1 or later. For description of older versions see Audio Settings (SIP) - older versions

From the Audio Settings page one can set loudspeaker volume, enable various audio signal processing feature and more.

Accessing the Audio Settings page

How to access the Audio Settings page depends on the mode of operation:

  • Edge mode: Edge Configuration > Audio Settings
  • SIP mode: SIP Configuration > Audio Settings
  • ICX-AlphaCom mode: Advanced ICX-AlphaCom > Audio Settings
Note icon
  • Available settings depends on device type and whether or not accessories are selected.
  • More options become available when enabling Advanced Configuration mode.


Normal Mode

"Normal mode" is the default view in the device web interface. One can set the level of the internal loudspeaker, as well as Line Out level and the output level on any accessories connected (e.g. handset, headset or external speaker).

In addition one can enable Automatic Gain Control (AGC), Active Noise Cancellation (ANC) and Automatic Volume Control (AVC). Not all these features are available for all types of devices.

Audio Settings - Normal mode



  • The available volume range for the loudspeaker depends on the intercom/device type. See this table for details.
  • When the loudspeaker volume is set to 0dB (default) it will produce a nominal loudspeaker output of 65 dBA at 0.5 meter distance.


Devices in ICX-AlphaCom mode

When a device is used in ICX-AlphaCom mode the following settings are controlled by the ICX-AlphaCom server, and configured from AlphaPro:

  • Internal Loudspeaker volume
  • Automatic Noise Cancellation (ANC)
  • Line Out level

These settings should not be changed in the device web interface, as they will be overwritten by the settings done from AlphaPro.

Volume settings controlled from AlphaPro


Advanced Configuration Mode

When selecting Advanced Configuration mode in the top right corner of the web interface, the Audio Settings menu change, and is divided into the following sections:

  • Audio Outputs
  • Audio Inputs
  • Audio signal processing
  • Other Audio Related Config (available in ICX-AlphaCom mode only)
Audio Settings - Advanced Configuration mode


By clicking on the yellow FACTORY RESET AUDIO SETTINGS all audio settings are reverted to factory default. This includes DAVC, VAD (Sound Detection) and Tone Test settings


Click on the wanted bar to expand the menu and view the options.

IP Intercom

The IP-station audio output has been normalized based on ITU recommendations. The input signal which is used for the output measurements is an ITU Voice Signal with an average RMS energy of -23 dBFS. Output levels are measured at a distance of 0.5 meter. The actual SPL of the IP-CROR station is 3 dB lower than indicated in the table below due to the covering of the speaker grill with a foil.
Kit output levels are based on the same speaker arrangement as for the comparable station.
