Advanced Sound Setup 9 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 subwoofer resulting in distortion. Use the LFE attenuator setting to reduce the signal fed to the subwoofer. 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. • You can't change this setting if the Record mode is on (see page 25). 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). 1 Press SYSTEM SETUP. 2 Press the 2 or 3 button until you see LFE in the display. 3 Use the 5 and ∞ buttons to set the amount of signal reduction. There are three settings: • LFE ATT 0 - default setting (no signal reduction) • LFE ATT 10 - the LFE channel signal level is reduced to avoid distortion • LFE OFF - the LFE channel is switched off completely. This may be useful late at night, for example. 1 Press SYSTEM SETUP. 2 Press the 2 or 3 button until you see D.R.C. in the display. 3 Use the 5 and ∞ buttons to select 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. MID - 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. 4 Press ENTER. 33 En
