51ADVANCED FUNCTIONSEven if all of your speakers are placed the same distance from thelistening 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. SeeFigure 84.Figure 84 – 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), SBL (surround back left),SBR (surround back right), SL (surround left) and SUB (subwoofer).NOTES:• The default distance setting for all speakers is 10 feet.• When the multiroom system is in use, the surround backchannels are automatically assigned to the multiroom system,as mentioned earlier. In that situation dashed lines will appearnext to the SBR and SBL channels as shown in Figure 84,and you will not be able to adjust the delay settings for thesechannels.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 lose synchronization. This is known as a “lip sync”problem. You may delay the audio for all channels by up to 80 millisec-onds to 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 picture and sound are back in sync.Move the cursor to the BACK TO MANUAL SETUP line and press theSet Button to return to the Manual Setup menu.You may adjust the delay settings without using the on-screen menusystem. Select a surround mode that uses all of the speakers in yoursystem. Press the Delay Button on the remote to display the A/V SYNCDELAY message. If you wish to adjust A/V Sync Delay as described inthe above note, press the Set Button to select it. Otherwise, use the⁄/¤ Buttons to scroll through the list of all loudspeakers in yoursystem. Press the Set Button when the speaker you wish to adjust isdisplayed, 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.Step Four – Setting Channel Output LevelsManuallyFor a conventional 2-channel receiver, the balance control enables theuser to control the stereo imaging by adjusting the relative loudness ofthe left and right channels, as heard at the listening position.With up to seven main channels plus a subwoofer, imaging becomesboth more critical and more complex. Unlike the rotary balance control,the goal of the AVR 245’s channel output adjustment process is toexamine the output level of each channel independently and ensure thateach is heard at the listening position with equal loudness.If you ran EzSet+, then the output levels were set automatically at thattime. However, if you prefer to make these adjustments manually, theAVR 245’s Channel Adjust menu allows you to do so, either using thesystem’s test tone or while playing source material.You may use a handheld SPL meter (available at most electronicsstores) set to the C-Weighting, Slow scale, or you may set the levels“by ear.”1. Make sure all speakers have been connected correctly.2. Adjust the size, crossover and delay for each speaker in your systemas described in Step Three in this section.3. If you are using a handheld SPL meter with source material, such asa test disc or another audio selection, play it now and adjust theAVR’s master volume control until themeter measures 75dB.
