How to Use Sound Check?

iTunes Sound Check feature causes songs to play back at the same relative volume level—if you have ever been jolted out of your chair because of one song’s volume level being much higher than the next one, you know why this is a good thing. Using the iPod’s Sound Check setting, you can cause the iPod to use the volume levels set by iTunes when Sound Check is on.
To use Sound Check, make sure it is on in iTunes. Then, connect your iPod to your computer so the iPod’s music will be updated, or you can perform a manual update if that is how you have configured iTunes for your iPod. After the update is complete, on the iPod choose Main menu, Settings. On the Settings menu, highlight Sound Check and press the Select button. The Sound Check setting will become On to show you that it is in use. When you play music back, it will play at the same relative volume level.
To return the volume level to the “normal” state, choose Main menu, Settings. Highlight Sound Check and press the Select button so that Off appears as the Sound Check setting.
