Most home theater main andsurround speakers perform best when configured as SMALL. Deep bass content in any channel with a SMALL speaker isrouted to the subwoofer(s).None .....................Select this when no speakers are installed.Yes/No..................Select “Yes” when a subwoofer is installed, “No” when a subwoofer is not installed.2 spkrs/1 spkr......Select the number of speakers to be used for the surround back channel.A subwoofer with sufficient low frequency playback capability can better handle deep bass than most main and surround speakers, and thesystem’s overall performance will be greatly enhanced when SMALL is set for the main (front) and surround speakers.To take full advantage of the performance of the Home THX certified speaker systems, set the front, center and surround speaker sizeparameters to “Small” and the subwoofer to “Yes”.For the majority of speaker system configurations, using the SMALL setting for all main and surround speakers and connected subwoofer(s)set to ON will yield the best results.When “Front” is set to “Small”, “Subwoofer” is automatically set to “Yes”, and when “Subwoofer” is set to “No”, “Front” is automaticallyset to “Large”.2-2.
