Setting the crossover frequency and low frequency distribution when playing Dolby Digital
and DTS signals
1
Select the Crossover Frequency mode.
Set the crossover frequency and subwoofer mode according to the speaker system being used.
Select the frequency.
3
Enter the setting.
The System Setup Menu reappears.
2
Select the Subwoofer Mode. Select the setting.
NOTES:
Assignment of low frequency signal range
The only signals produced from the subwoofer channel are LFE signals (during playback of Dolby Digital or DTS signals) and the low
frequency signal range of channels set to Small in the setup menu. The low frequency signal range of channels set to Large are
produced from those channels.
Crossover Frequency
When Subwoofer is set to Yes at the Speaker Configuration Setting, set the frequency (Hz) below which the bass sound of the
various speakers is to be output from the subwoofer (the crossover frequency).
For speakers set to Small, sound with a frequency below the crossover frequency is cut, and the cut bass sound is output from the
subwoofer instead.
NOTE:For ordinary speaker systems, we recommend setting the crossover frequency to 80 Hz. When using small speakers, however,
setting the crossover frequency to a high frequency may improve frequency response for frequencies near the crossover frequency.
Subwoofer mode
The subwoofer mode setting is only valid when Large is set for the front speakers and YES is set for the subwoofer in the Speaker
Configuration settings (see page 18).
When the LFE+MAIN playback mode is selected, the low frequency signal range of channels set to Large are produced simultaneously
from those channels and the subwoofer channel.
In this playback mode, the low frequency range expand more uniformly through the room, but depending on the size and shape of the room,
interference may result in a decrease of the actual volume of the low frequency range.
Selection of the LFE play mode will play the low frequency signal range of the channel selected with Large from that channel only.
Therefore, the low frequency signal range that are played from the subwoofer channel are only the low frequency signal range of LFE (only
during Dolby Digital or DTS signal playback) and the channel specified as Small in the setup menu.
Select the play mode that provides bass reproduction with quantity.
When the subwoofer is set to Yes, bass sound is output from the subwoofer regardless of the subwoofer mode setting in surround modes
other than Dolby/DTS.
In surround modes other than Dolby Digital and DTS, if the subwoofer is set to YES, the low frequency portion is always output to the
subwoofer channel. For details, refer to Surround Modes and Parameters on page 60.
