30INITIAL SETUPFigure 49 – EzSet/EQ – Speaker DelayNOTE: The AVR 147 is also capable of setting a different typeof delay, called A/V Sync Delay. A/V Sync Delay is used tocompensate for lip sync problems that may occur when a videodisplay device or set-top box causes delays while digital videosignals are processed. It simultaneously adds a delay to allspeaker channels in the system. A/V Sync Delay is not setduring EzSet/EQ. It may be set while watching a program asfollows: press the Delay Button on the remote and the firstsetting displayed is A/V Sync Delay. Press the Set Button toselect it and then use the ⁄/¤ Buttons to adjust it.Speaker Level: During this test, EzSet/EQ ensures that all speakerssound equally loud at the listening position. During a surround soundpresentation, it is common, at times, for the surround channels to soundless prominent, or not to be used at all. By setting the baseline channellevels correctly, the settings programmed by the director can be evenmore effective.Speaker Size: This test checks the low-frequency range capabilitiesof each of your speakers to ensure that low-frequency sounds are notsent to speakers unable to reproduce them efficiently. Each of the mainspeakers in your system will be assigned a value of Large or Small,depending solely on how it handles low frequencies.Speaker Crossover: This test determines the lowest frequency eachof your main speakers is capable of handling effectively, in order toset the highest frequency the subwoofer should reproduce. The systembalances the need to ensure that all frequencies are reproduced forsmooth transitions between the subwoofer and main speakers withoutlosing any information, against the need to avoid overtaxing smallersatellite speakers.Equalization (EQ): Many factors unique to the listening room can affectthe overall sound of a home theater system. For example, a roomconsisting of hardwood floors and large expanses of glass can soundlivelier, with added reverberation, while a carpeted room fitted with draperiescan dampen sound waves. In addition, the shape of the room can affectfrequency response. If a room has a small alcove near a doorway, forexample, you may notice a difference in bass response depending onwhether you are standing opposite the alcove or to one side of it.EzSet/EQ is capable of measuring the impact room characteristics andspeaker placement have on each speaker’s performance, and of makingadjustments to low-frequency response to compensate. You may hearEzSet/EQ repeat tones from various speakers a number of times as itperforms the equalization.When EzSet/EQ has finished running all of these tests, a screen similarto the one in Figure 50 will appear. The TEST DONE-UNPLUG MICmessage will disappear after a few seconds, replaced by a speakerchannel name. You may move the cursor to that line and scroll throughthe speaker channels to review the EzSet/EQ results. If they are satisfac-tory, return the cursor to the SAVE SETTING line, and press the SetButton to save the EzSet/EQ settings. If the settings are close but youwould like to tweak them, save the EzSet/EQ settings and then followthe instructions in the Advanced Functions section to manually adjust thevarious configuration settings. If the settings are completely unsatisfactory,use the ‹/› Buttons to select NO and press the Set Button. Checkyour speaker connections and placements, then repeat EzSet/EQ.Figure 50 – EzSet/EQ – CompletedConfigure SourcesThis is the last step in the configuration process. In the Installationsection, you physically connected various cables between your sourcedevices and the AVR. In this section, you will assign the various audioand video inputs to their sources, ensuring that the AVR uses thecorrect connections each time you select a source.Press the OSD Button to view the Master Menu. The cursor willbe pointing to the INPUT SETUP line, and you need only press theSet Button to display the Input Setup menu. See Figure 51.Figure 51 – Input Setup Menu Screen
