Select Off when no cen-ter speaker is connected. (If you select Nml/THX in step7. “Large” cannot be selected here.)9. When the surround (left and right) speaker setting menu(Surround) appears, select Surround Nml/THX, Largeor Off in the same way as step 6, then press the Nextbutton. Select Off when no surround speaker is con-nected. (If you select Nml/THX in step 7. “Large” can-not be selected here)10. When the surround back (left and right) speaker set-ting menu (Sur. Back) appears, select Sur. Back Nml/THX, Large or Off in the same way as step 6, then pressthe Next button. Select Off when no surround backspeaker is connected. (If you select Nml/THX in step 7.“Large” cannot be selected here. If you select the sur-round to Off in step 9, skip this step and surround backspeakers select Off automatically.)• Select Nml/THX if the speaker is not capable of pro-ducing clean, deep bass energy at output levels thatmatch those produced by a typical poweredsubwoofer. All bass below 80Hz in that channel isremoved from that speaker and is sent to the sub-woofer (or sent to the front speakers if subwoofer isset to off) in all listening modes. Most speakers shouldbe considered Nml/THX.If you have THX certified speakers, select the Nml setting.• Select Large if the speaker is capable of producingclean, deep bass energy at output levels that matchthose produced by a typical powered subwoofer. Allbass below 80Hz in that channel is left in that speakerin all listening modes.NOTE : If you set the front or center speaker to Large, thesubwoofer may not output audio depending on thesetups of the input signal, speakers and listen mode.11. If you have a subwoofer as part of your home theater speakersystem and have set your left & right front speakers to Large,SW Re-Mix mode gives you the flexibility to choose howbass information is distributed to your speakers. (As men-tioned above, most speakers will perform best when set toNml/THX.)If the Re-Mix Off-THX option is selected, bass from thefront left and front right channels will go ONLY to the frontleft and front right speakers. The subwoofer will only re-ceive a bass signal from the LFE channel of Dolby Digitaland DTS programs, and from any channels with speakersthat you have designated as Nml/THX. This selection is pre-ferred by THX.If the Re-Mix On option is selected, you will send the bassfrom the front left and right channels to the front left &right speakers AND the subwoofer simultaneously. Whilethis setting keeps your subwoofer active in all listeningmodes, it can also cause the bass to sound indistinct (or"muddy") because it is now coming from up to 3 differentspeakers at once.If your home theater speaker system includes a subwooferand you have set your front left & right speakers to 'Large',we suggest that you initially use the Re-Mix Off-THX set-ting. If this produces weak-sounding bass in your room,change to the Re-Mix On setting.12.

(To set the subwoofer level, see “Settingthe Subwoofer Level” on page 38.) When all the speakers areset at the same volume level, your system will create a morerealistic, spacious surround sound environment.You can balance the speakers by ear, or you can use a soundlevel meter. Using a meter lets you balance your system moreaccurately, and lets you set the reference playback level. (See“Balancing the Speaker Levels with a Sound Level Meter”on page 42)
