Configuring the digital surround processor

If you have a subwoofer you can use it to augment the bass
from the centre channel (Layouts B or H). If the subwoofer is not
very high quality we recommend using it only for the cinema
presets, and not for music (Layouts AB or AG).
With Dolby Digital sources an additional option is to use the
subwoofer for the LFE channel.
Small main speakers
If your main left and right speakers are small and do not have a
good bass response, or your room is large, you can use one or
more subwoofers to handle the bass for the system by selecting
one of the layouts in the lower half of the table.
All the layouts include at least one subwoofer. If there is only
one subwoofer this provides mono bass for all the channels.
If you have two subwoofers you have a choice of using them for
mono and surround (Layout␣ J), left and right (Layout K), or
left+right and centre (Layout F).
Surrounds
All the layouts allow you to add up to two rear surrounds. If you
do not have rear surrounds, set No Surrounds in Config. If you
have only one rear surround connect it to output 8 and set 1
Surround in Config.
Many of the layouts also allow you to add up to two side
surrounds. To use side surrounds in a layout that supports them
set 4␣ Surrounds in Config. For more information see To specify
the number of surround speakers, page 26.
