54ADVANCED FUNCTIONSFigure 86 – 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 and noted in Table A3 in the appendix.The default unit of measurement is feet. If you wish to change the unitto meters, move the cursor down to the UNIT line, press the Set Buttonand use the ‹/› Buttons to change the unit to METER.Use the ⁄ /¤ Buttons to move the cursor to the Front Left line, pressthe Set Button then use the ‹/› Buttons to change the measurementas needed. Use the ⁄ /¤ Buttons to move to each speaker in turn –Center, Front Right, Surround Right, Surround Back Right, SurroundBack Left, Surround Left and Subwoofer.NOTE: When the multiroom system is in use, the surround backchannels are automatically assigned to the multiroom system, asmentioned earlier. In that situation you will not be able to adjust thedelay settings for these channels; the cursor will skip past them.A/V SYNC DELAY: This line allows you to compensate for a situationin which one of your source devices, or your video display, introducesa significant amount of video processing that causes the audio andvideo parts of the signal to lose synchronization. This is known as a“lip sync” problem. You may delay the audio for all channels by up to80 milliseconds 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.RESET: This line is used if you wish to reset all of the speaker delaysettings to the factory default of 10 feet (3.0 meters) at once. Simplyhighlight it and press the Set Button.Move the cursor to the left to select the next submenu.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 247’s channel output adjustment process is toexamine the output level of each channel independently and ensurethat each is heard at the listening position with equal loudness.If you followed the instructions in the Initial Setup section, then youlet EzSet/EQ handle this critical task for you, simply and automatically.However, if you prefer to make these adjustments manually, theAVR 247’s Channel Adjust menu allows you to do so, either using thesystem’s test tone or while playing source material. In addition, this isthe only method for adjusting the level of the subwoofer.You may use a handheld SPL meter (available at most electronicsstores) set to the C-Weighting, Slow scale.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.3. If you are using a handheld SPL meter with source material, suchas a test disc or another audio selection, play it now and adjust theAVR’s master volume control until the meter measures 75dB.4. There are several methods of adjusting the channel output levels,using either the test tone or source materials. In all cases, you maymeasure the channel levels in one of two ways:a) By ear. Try to adjust the levels so that all channels sound equally loud.b) Using a handheld SPL meter set to the C-Weighting, Slow scale. Try toadjust each channel so that the meter reads 75dB.The best method of setting the output levels is by running EzSet/EQ, asdescribed in the Initial Setup section. If any finer adjustments are desired,we recommend using the full-OSD system to make the adjustments whileplaying the AVR’s built-in test tone and measuring the output using anSPL meter. Less effective would be to measure the output by ear. Theadjustments may also be made using the remote’s Test Tone commandor Channel command. Although the Channel command is also accessibleusing the front-panel controls, we don’t recommend doing so, as themeasurements cannot be made from the listening position.A. Using the Remote Control With the Test ToneWhile sitting in the listening position, press the Test Button on theremote. The test tone will start playing at the front left channel. After
