Hooking Up and Setting Up the Speaker System Tip The surround speaker placement parameter is designed specifically for implementation of the Digital Cinema Sound modes with virtual elements. With the Digital Cinema Sound modes, speaker placement is not as critical as other modes. All modes with virtual elements were designed under the premise that the surround speaker would be located behind the listening position, but presentation remains fairly consistent even with the surround speakers positioned at a rather wide angle. However, if the speakers are pointing towards the listener from the immediate left and right of the listening position, the sound fields with virtual elements will not be as effective. Nevertheless, each listening environment has many variables, like wall reflections. Therefore, we recommend that you playback multi channel surround encoded software and listen to the effect each setting has on your listening environment. Choose the setting that provides a good sense of spaciousness and that best succeeds in forming a cohesive space between the surround sound from the surround speakers and the sound of the front speakers. If you are not sure which sounds best, select "PL. LOW" and then use the speaker distance parameter and speaker level adjustments to obtain proper balance. Only when you use the speaker system other than the supplied one, be sure to set the following parameters. For details on "NORM. SP." (Normal Speaker), see page 15. x Sub woofer selection ( SW S.W. XXX) • If you connect a sub woofer, select "YES". • If you do not connect a sub woofer, select "NO". This activates the bass redirection circuitry and outputs the LFE signals from other speakers. x Front speaker size ( L R XXXXX) • If you connect large speakers that will effectively reproduce bass frequencies, select "LARGE". Normally, select "LARGE". • If the sound is distorted, or you feel a lack of surround effects when using multi channel surround sound, select "SMALL" to activate the bass redirection circuitry and output the front channel bass frequencies from the sub woofer. • When the front speakers are set to "SMALL", the center and surround speakers are also automatically set to "SMALL" (unless previously set to "NO"). • When the sub woofer is set to "NO", the front speakers are automatically set to "LARGE" and you cannot change this setting. x Center speaker size ( C XXXXX) • If you connect a large speaker that will effectively reproduce bass frequencies, select "LARGE". Normally, select "LARGE". However, if the front speakers are set to "SMALL", you cannot set the center speaker to "LARGE". • If the sound is distorted, or you feel a lack of surround effects when using multi channel surround sound, select "SMALL" to activate the bass redirection circuitry and output the center channel bass frequencies from the front speakers (if set to "LARGE") or sub woofer.*1 • If you do not connect a center speaker, select "NO". The sound of the center channel will be output from the front speakers.*2 continued 17GB
