Setup: Sound: Sound Modes: PRESETNAME: Frequency Tilt
Frequency Tilt can be considered to be a
combination of Bass and Treble settings
in a single parameter. When Frequency
Tilt is set to a low value, the low
frequency content of your audio signal is
increased and the level of the high
frequency content is reduced. If the
Frequency Tilt is set to a high value,
then the opposite will be true.
The Frequency Tilt function will have no
effect on the audio signal at its middle
setting.
Note that Frequency Tilt can have
different settings for different Sound
Modes.

of all settings of the Frequency Tilt control.
Note that this response is applied to each
input channel.
Setup: Sound: Sound Modes: PRESETNAME: Sound Enhance
The Sound Enhance setting is similar to
the Frequency Tilt setting in that it
affects the low and high frequency
bands with a single slider. Increasing the
Sound Enhance value will increase the
level of the bass and treble bands while
reducing the midrange. Decreasing the
Sound Enhance value will have the
opposite effect.
The Sound Enhance setting will have no
effect on this audio signal at its middle
setting.
Note that Sound Enhance can have
different settings for different Sound
Modes.

input channel.
Setup: Sound: Sound Modes: PRESETNAME: Speech Enhance
The Speech Enhance setting allows you
to increase the intelligibility of dialogue,
making speech and voices easier to
understand.
Note that the Speech Enhance setting
will have no effect on the audio signal
when it is at its lowest setting.
