LFE Crossover Frequency

Adjusts the cut-off frequency (20~250Hz) for LFE (low-frequency effects) signals.
Xonar Essence ST filters out the bass signals below the crossover frequency
from small speaker channels and forwards them to the subwoofer. The higher the
crossover frequency, the more bass signals are subtracted.

Smart Volume Normalization

Smart Volume NormalizationTM (SVN) automatically keeps all music or video/
TV audio output at a constant level to reduce manual adjustment inherent with
sound sources of different loudness. It allows you to listen to various content, like
MP3, TV program, DVD video and even games at a consistent sound level. The
following graph shows how signals 1 and 2 adjust to the same level (for example,
10dB below full scale) after you turn on SVN. Please note that lower volume music
2 becomes louder when you turn on SVN while higher volume music 1 becomes
quieter.
