Advanced sound settings
This chapter covers advanced settings to further optimize the sound of your system.
LFE attenuator
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 sub-woofer
resulting in distortion. Use the LFE attenuator setting to reduce the signal fed to the sub-
woofer.
Note: The LFE attenuator only works with sources that contain an LFE channel. It is
not a general level control for the sub-woofer.
1 Press SYS then SETUP.
2 Press the @ or # button until you see LFE ATT in the display.
3 Use the % and fi buttons to set the amount of signal reduction.
There are three settings:
•ATT 0 – default setting (no signal reduction)
•ATT 10 – the LFE channel signal level is reduced to avoid distortion
•OFF – the LFE channel is switched off completely. This may be useful late at night,
for example.
4 Press ENTER to make the setting.
Dynamic Range Control
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.
1 Press SYS then SETUP.
2 Press the @ or # button until you see D.R.C. in the display.
3 Use the % and fi buttons to sselect a dynamic range setting.
•D.R.C. OFF – default setting (no change to the dynamics)
•D.R.C. LOW – the dynamic range is reduced by a small amount.
•D.R.C. MEDIUM – mid setting
•D.R.C. HIGH – the dynamic range is reduced by a large amount (good for
listening at very low volume).
4 Press ENTER to make the setting.
