Bass management
When switched on, the low frequency content in the audio signal may be re-routed to
different loudspeakers, depending on their capabilities. Bass management redirects low
frequencies to the most capable loudspeakers in your current setup. For example, if you
have two small loudspeakers and a subwoofer, the low frequency signals will be directed
to your subwoofer instead of to your smaller main speakers.
Frequency tilt
Frequency tilt can be considered a combination of bass and treble controls in a single
parameter. When frequency tilt is set to a low value, the low frequency content of the
audio signal is increased and the level of the high frequency content is reduced. The
frequency tilt can be set for each sound mode.
Sound enhancement
Affects both low and high frequency bands with a single slider. Increasing the sound
enhancement increases the level of bass and treble bands while reducing midrange.
Decreasing the sound enhance decreases the level of bass and treble but increases the
midrange.
Speech enhancement
Allows you to increase the intelligibility of dialogue, making speech and voices easier to
understand. It has no effect on the audio signal when at its lowest setting.
Balance and Fader
Re-direct input signal to different output channels in your speaker setup. For example,
adjusting the balance l/r all the way to the left will direct all the signals only to the
speakers in your setup that have a speaker role on the left (that is left front, left surround,
etc.) and adjusting the fader b/f all the way to the left will direct all the signals only to the
speakers in your setup that have speaker roles as rear speakers (that is right back, left
back, etc.).
Listening style
The audio signal can be modified according to your listening style. If your primary activity
is listening to the audio signal, you should set the option to Active. However, if listening is
a secondary activity, for example, in case of background music during dinner, the setting
should be Passive.
LFE input
Low Frequency Effects (LFE) are used for additional sound effects for movies. However,
some multichannel music releases contain a signal on the LFE channel. Consequently,
when listening to this type of music, the LFE input should be switched off to avoid
unwanted audio.
