28INITIAL SETUPThe LFE line sets the frequency for a low-pass filter that determineswhat information is sent to the subwoofer for playback. Since the sub-woofer output combines low-frequency information for all channels, inorder 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.Looking at each of your three speaker-group settings in this menu,determine which group is set to the highest frequency. Move the cursorto the LFE line, and use the ‹/› Buttons to select that speaker group.If all three speaker groups have the same setting, you may leave theLFE filter to its factory default of the LEFT/RIGHT speaker group.Move the cursor to the BACK TO MANUAL SETUP line and press theSet Button to return to the Manual Setup menu.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 the lis-tening position, you should not skip this menu.On the Manual Setup menu, move the cursor to the DELAY ADJUSTline and press the Set Button to display the Delay Adjust menu.Figure 40 – Delay Adjust Menu ScreenThis menu requires you to enter the distance from each speaker to thelistening position, which you measured in Step Two – Measure SpeakerDistances.The default unit of measurement is in feet. If you wish to change the unitto meters, move the cursor down to the UNIT line, and use the ‹/›Buttons to change the unit to METER.Use the ⁄/¤ Buttons to move the cursor to the FL (front left) line;then use the ‹/› Buttons to change the measurement as needed.Use the ⁄/¤ Buttons to move to each speaker in turn – CEN(center), FR (front right), SR (surround right), SL (surround left) andSUB (subwoofer).DELAY RESET: This line is used if you wish to reset all of the speakerdelay settings to the factory default of 10 feet (3.0 meters) at once. Usethe ‹/› Buttons to change the setting of OFF to ON. If you changeany speaker’s setting, this line will automatically revert to OFF.A/V SYNC DELAY: This line allows you to compensate for a situation inwhich one of your source devices, or your video display, introduces asignificant amount of video processing that causes the audio and videoparts of the signal to get out of sync. This is known as a “lip sync” prob-lem. You may delay the audio for all channels by up to 80 millisecondsto compensate.NOTE: We recommend that you adjust the A/V Sync Delayusing the Delay Button on the remote, rather than in this menu,so that you can view the picture while adjusting the audio delay.With the program playing, press the Delay Button, and the A/VSYNC DELAY message will appear on the front panel and in thesemi-OSD display. Press the Set Button to display the currentdelay setting, and use the ‹/› Buttons to adjust the settinguntil the synchronization issue is resolved.Move the cursor to the BACK TO MANUAL SETUP line and press theSet Button to return to the Manual Setup menu, or simply press theOSD Button to exit the menu system.Step Four – EzSet Output Level CalibrationThis is an important step in the configuration process, and should not beskipped.By now you should have connected all of your speakers and sourcesand your video display. You should have turned on the receiver andused the Manual Setup menus to program each of your speakers asLarge or Small.Sit in the listening position with the remote control, and make sureto eliminate external noises for the few minutes needed to run theEzSet procedure.Use the volume control buttons on the remote to adjust the volumeto –15dB.Now point the remote at the receiver and press the SPL Button until theLED blinks, then press the “5” Key. The procedure works best if youhold the remote at about ear level, pointed toward the receiver. Try notto tilt the remote out of line with the IR receiver on the AVR’s front panel.Figure 41 – EzSet (SPL) Button
