The Sony HT-S400 has a disappointing selection of sound enhancement features. If you want to customize its sound, you don't have a lot of choices on hand, aside from its subwoofer level adjustment (though the button on the remote reads 'Bass', this feature only controls the amount of bass reproduced by the sub). The remote also gives you access to its dialogue enhancement mode (called Voice) and its night mode, which balances the volume level in your programs. You can't adjust the amount of bass reproduced by the bar, and you can't control the treble, either. You can't turn off its S-Force Pro Front Surround feature, either.
