How to Adjust the Preamp Volume in iTunes

6 of 11 in Series: The Essentials of Setting Up and Playing Content in iTunes

You can easily adjust the preamp volume in the iTunes Equalizer dialog. You adjust the preamp volume before you move the equalizer sliders in the Equalizer dialog.

The iTunes equalizer, as shown the following figure, offers a Preamp slider on the far-left side. You can increase or decrease the volume in 3-decibel (dB) increments up to 12 dB. Decibels are units of measure for the intensity (or volume) of the frequencies. You can adjust the volume while playing the music to hear the result right away.

Use the Preamp slider to adjust the volume across all frequencies.

If you want to make any adjustments to frequencies, you might need to adjust the preamp volume first if volume adjustment is needed and then move on to the specific frequencies.
