This chapter covers advanced settings to further
optimize the sound of your system.
The LFE (low frequency effects) channel carries ultra
low bass sound to add weight to effects in Dolby Digital
and DTS soundtracks. This channel can overload the
subwoofer resulting in distortion. Use the LFE attenua-
tor setting to reduce the signal fed to the subwoofer.
The LFE attenuator only works with sources that
contain an LFE channel. It is not a general level control
for the sub-woofer.
• You can't change this setting if the Record mode is
on (see page 25).

There are three settings:
• – default setting (no signal reduction)
• – the LFE channel signal level is
reduced to avoid distortion
• – the LFE channel is switched off
completely. This may be useful late at night, for
example.
The dynamic range of a source is the difference between
the quietest and the loudest sounds. The dynamic range
of Dolby Digital soundtracks can be very great. This
makes them exciting, but it also means that when you
turn the volume down you can easily lose quiet dialog.
Switch on Dynamic Range Control to even out the
soundtrack volume.
• You can't change this setting if the Record mode is
on (see page 25).

dynamics)

small amount.

large amount (good for listening at very low volume).
