53ADVANCED FUNCTIONS• If you set the front speakers to LARGE, you may select from threepossible settings for the subwoofer.SUB L/R+LFE: This setting sends all low-frequency informationto the subwoofer, including both information that would normallybe played through the front left and right speakers and the speciallow-frequency effects (LFE) channel information.SUB (LFE): This setting plays low-frequency information containedin the left and right program channels to the front speakers, anddirects only the LFE channel information to the subwoofer.NONE: This setting steers all low-frequency information to thefront speakers, and no information to the subwoofer output. Usethis setting if you have a passive subwoofer, or a powered sub-woofer that you connected to the front speaker outputs.NOTE: If you are using a Harman Kardon HKTS speakersystem, select the SMALL setting for the LEFT/RIGHT, CENTER,SURROUND and SURR BACK lines, and the subwoofer willautomatically be set to SUB (LFE).Move the cursor to the left to select the next submenu.The speaker sizes may also be configured without using the on-screenmenu system. Press the Speaker Setup Button on the remote, anduse the ⁄ /¤ Buttons to select the desired speaker group (FrontSpeakers, Center Speaker, Surround Speakers, Surround Back Speakers,Subwoofer). Press the Set Button to display the current setting for thespeaker group, and use the ⁄ /¤ Buttons again to change the setting.Press the Set Button to return to the previous display, or wait a fewseconds for the AVR to return to normal operation on its own.NOTE: The Speaker/Channel Indicators on the front panel ofthe receiver (see Figure 82) will display the speaker size settingsas follows. For each speaker configured as SMALL, a single boxwill appear in the position for that speaker. For each speakerconfigured as LARGE, a double box will appear in its position.If a speaker is configured as NONE, no box will appear. Thesubwoofer will be indicated by a single box, or no box if nosubwoofer has been configured. The letters inside the boxesappear when a digital signal is being received that has thatchannel discretely encoded. The letters flash when the signal isnot present, such as when a DVD is paused. A line will connectthe SBL and SBR boxes when a 6.1-channel signal is detected,indicating that the same signal is playing through both speakers.Figure 82 (repeated) – Speaker/Channel Input IndicatorsSpeaker Crossover MenuOn the Manual Speaker Setup menu, move the cursor to the Cross-Over line and press the Set Button to display the Speaker Crossovermenu. See Figure 85.Figure 85 – Speaker Crossover Menu ScreenSetting the Speaker Crossover menu correctly ensures that your speakersare properly used so that they sound their best. Although you could skipthis step the first time you use the receiver, we recommend that youtake the few extra minutes to enter the correct crossover settings.You may select from seven possible settings: 40Hz, 60Hz, 80Hz,100Hz, 120Hz, 150Hz or 200Hz. Depending upon the frequencyresponse of your speakers, which you recorded in Step One –Determine Speaker Size, for each speaker group select the numberthat matches or is just above the low end of your speaker’s frequencyresponse. You may record the speaker crossover settings in Table A5in the appendix.The Subwoofer line sets the frequency for a low-pass filter that deter-mines what information is sent to the subwoofer for playback. Since thesubwoofer output combines low-frequency information for all channels,in order to make sure that no information is lost due to different speakershaving different capabilities, the subwoofer filter should be matched tothe highest crossover frequency used for any speaker group.Examine each of your speaker-group settings in this menu, and deter-mine which group is set to the highest frequency. Move the cursor tothe Subwoofer line, press the Set Button and use the ‹/› Buttons toselect that speaker group. If all speaker groups have the same setting,you may leave the LFE filter at its factory default of the LEFT/RIGHTspeaker group.Move the cursor to the left to select the next submenu.It is not possible to adjust the speaker crossover settings without usingthe on-screen menu system.Delay Adjust MenuAs explained above in Step Two – Measure Speaker Distances, some-times the speakers are placed at different distances from the listeningposition, which can muddy the sound, as sounds are heard earlier orlater than desired.Even if all of your speakers are placed the same distance from thelistening position, you should not skip this menu.On the Manual Speaker Setup menu, move the cursor to the DelayAdjust line and press the Set Button to display the Delay Adjust menu.See Figure 86.L CLFERSL SRSBL SBR
