Adjusting the bass, treble, balance or loudness of your Sonos speakers can be done in a few simple steps using the Sonos app. You can adjust the Equalization (EQ) of each Sonos speaker from the “Room Settings” menu.

You can adjust the following equalization settings:

• Bass adjusts the lower frequency sounds, such as bass guitar, or drum kick.
• Treble adjusts the higher frequency sounds, such as an electric guitar or violin notes.
• Balance increases or decreases the volume of the left or right speaker. Balance on the PLAY:1 is only adjustable when it is used in a stereo pair.
• Loudness is designed to compensate for normal changes in the ear’s sensitivity when listening to audio at low volumes. When enabled, this setting will boost certain frequencies, including bass, during low listening volumes.

On iOS or Android:

1. From the Sonos music menu, tap Settings > Room Settings.
2. Tap to select a room your speaker is located in.
3. Tap “EQ,” and then drag your finger across the sliders to make adjustments.

On Mac or PC:

1. Choose one of the following:
   • On a Mac, select Sonos > Preferences > Room Settings.
   • On a PC, select Manage > Settings > Room Settings.
2. Select a room from the drop-down menu.
3. Select the “EQ” tab to adjust the equalization of your Sonos player.

On a Mac, the “Sonos” menu can be found in the toolbar in the top left corner of the screen. On a PC, the “Manage” menu is found at the top left of the Sonos application.
