24 SYSTEM CONFIGURATIONSystem ConfigurationManual Output Level AdjustmentOutput levels may also be adjusted manually,either to set them to a specific level with an SPLmeter, or to make fine tuning adjustments to thelevels obtained using the EzSet remote.Manual output level adjustment is most easilydone through the CHANNEL ADJUSTmenu (Figure 9). If you are already at the mainmenu, press the ¤ Button D until the on-screen cursor is next to the CHANNELADJUST line. If you are not at the main menu,press the OSD Button v to bring up theMASTER MENU (Figure 1), and then pressthe ¤ Button D four times so that the on-screen cursor is next to the CHANNELADJUST line. Press the Set Button F tobring the CHANNEL ADJUST menu (Figure9) to the screen.Figure 9When the CHANNEL ADJUST menu firstappears, the test tone is off. Use the ⁄/¤Navigation Button D to select any channelfor adjustment using an external source, such asa test disc, from which to judge the output levels.After the cursor is pointing to the channel tobe adjusted, press the ‹/› Navigation ButtonE& to raise or lower the output level.However, before proceeding with any manualadjustment we recommend that you first use theAVR’s internal test tone generator and automaticsequencer to send a tone to each channel so thatyou may verify that all speaker connections havebeen properly made.To turn the test tone on and have it automatical-ly circulate among the channels where a speakerhas previously been configured (see page 24),press the ⁄/¤ Navigation Button D untilthe cursor is pointing to the TEST TONESEQ line on the menu. Next, press the ‹/›Navigation Button E& until AUTO isshown. Next, press the ¤ Navigation ButtonD once so that the cursor is pointing toTEST TONE. Press the ‹/› NavigationButton E& once to immediately start thetest tone at the Front Left speaker. It will circulateclockwise around the room, playing for two sec-onds in each speaker before switching to thenext speaker position. The cursor will blinknext to the active speaker to indicate whichspeaker the sound should be coming from.IMPORTANT NOTE: Because this test noise willhave a much lower level than normal music, thevolume must be lowered after the adjustment forall channels is made, but BEFORE you return tothe main menu and the test tone turns off.NOTE: Remember to verify that the speakers havebeen properly connected. As the test noise circu-lates, listen to make certain that the sound comesfrom the speaker position shown in the MainInformation Display ˜. If the sound comesfrom a speaker location that does NOT match theposition indicated in the display, turn the AVR offusing the Main Power Switch 1 and check thespeaker wiring or connections to external poweramplifiers to make certain that each speaker isconnected to the correct output terminal.After checking for speaker placement, let the testnoise circulate again, and listen to see whichchannels sound louder than the others. Using thefront left speaker as a reference, press the ‹/›Buttons E& on the remote to bring allspeakers to the same volume level. When one ofthe ‹/› buttons is pushed, the test noise circula-tion will pause on the channel being adjusted togive you time to make the adjustment. When yourelease the button, the circulation will resumeafter five seconds. The on-screen cursor andthe test noise can also be moved directly to thespeaker to be adjusted by pressing the ⁄/¤buttons D on the remote.Continue to adjust the individual channels untilthe volume level sounds the same from eachspeaker. Note that adjustments should be madewith the ‹/› Buttons E& on the remoteonly, NOT the main volume controls.If you are using a sound-pressure level (SPL)meter for precise level adjustment with the testtone, open the main Volume Control ) to -15dB and set the individual output level for eachchannel so that the meter reads 75dB, C-Weighted Slow. After all settings are made turnthe main volume down.You may also make these same adjustments withcomplete manual control over the channel beingadjusted by pressing the⁄/¤ NavigationButton D until the cursor is pointing to theTEST TONE SEQ line on the menu and thenusing the ‹/› Navigation Button E& toselect MANUAL in the highlighted video. In theMANUAL mode, the test tone will also startimmediately, but the tone will only be movedto another channel by pressing the ⁄/¤Navigation Button D. When the manualsequencing mode is active, the tone is turned offby pressing the ⁄/¤ Navigation Button Duntil the cursor is pointing to the TESTTONE line and the ‹/› Navigation ButtonE& is then pressed to select OFF in thehighlighted video.NOTE: The subwoofer output level is notadjustable using the test tone. To change thesubwoofer level, follow the steps for OutputLevel Trim Adjustment on page 32.When all channels have an equal volume level,the adjustment is complete. Now turn theVolume ) down to about –40dB, otherwisethe listening level may be too high as soon asthe source’s music starts to play. To exit thismenu, press the ⁄/¤ buttons D until theon-screen › cursor is next to the BACK T OMASTER MENU line, and then press theSet Button F to return to the MASTERMENU.The output levels may also be adjusted at anytime using the remote control and semi-OSD sys-tem. To adjust the output levels in this fashion,press the Test Button 8. As soon as thebutton is pressed, the test tone will begin tocirculate as indicated earlier. The correct channelfrom which the test noise should be heard will beshown in the lower third of the video screen andin the Main Information Display ˜. Whilethe test noise is circulating, the proper channelposition will also be indicated in the Speaker/Channel Input Indicators $ by a blinkingletter within the correct channel. Turn up theVolume ) until you can hear the test noiseclearly.To adjust the output level, press the ⁄/¤ but-tons D until the desired level is shown in thedisplay or on screen. Once the buttons arereleased, the test noise will begin to circulateagain in five seconds.When all channels have the same output level,turn the Volume ) down to about –40dB,otherwise the listening level may be too high assoon as the source’s music starts to play.Afterwards press the Test Tone Selector 8button again to turn the test tone off andcomplete the process.IMPORTANT NOTE: The Output level adjust-ment made will be effective for all inputs, butonly for the actual surround mode selected. To beeffective for any other mode select that mode(with any input) and repeat the level adjustmentdescribed above. This will also allow you to com-pensate level differences between speakers, thatmay be different with each surround mode, or toincrease or decrease the level of certain speakersintentionally, depending on the surround modeselected.Note: Output level adjustment is not availablefor the VMAx or Surround Off mode, as nosurround speakers are used (so level differencesbetween the speakers in the room cannot occur).But to compensate level differences betweenstereo, VMAx and other surround modes (inde-pendently from the input selected) the outputscan be adjusted with the Level Trim Adjustmentprocedure, see page 32, also for the Surround Off(Stereo) and VMAx modes.* C H A N N E L A D J U S T *F L : 0 d B S B R : 0 d BC E N : 0 d B S B L : 0 d BF R : 0 d B S L : 0 d BS R : 0 d B S U B : 0 d BC H A N N E L R E S E T : O F FT E S T T O N E S E Q : M A N U A LT E S T T O N E : O F FB A C K T O A U D I O S E T U P→
