36INITIAL SETUPdisplay 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 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. During the SpeakerSize test a screen similar to the one shown in Figure 58 will appear, withthe speaker position changing as each speaker is measured.Figure 58 – EzSet/EQ: Speaker Size/Crossover TestAt the same time the overall size of the speaker’s frequency range ismeasured, the AVR will measure the crossover, which is the lowestfrequency each of your main speakers is capable of handling effectively,in order to set the highest frequency the subwoofer should reproduce.The system balances the need to ensure that all frequencies are repro-duced for smooth transitions between the subwoofer and main speakerswithout losing any information, against the need to avoid overtaxingsmaller satellite speakers.NOTE: The crossover determined by EzSet/EQ is not the sameas the crossover frequency specification that appears in thespeaker’s manual. EzSet/EQ is measuring the point at which theaudio signal must be passed from the main speaker to the sub-woofer. For an individual loudspeaker, the manufacturer specifiesthe point or points at which the audio signal is passed from onetransducer within the speaker to another.Equalization (EQ): Many factors unique to the listening room can affectthe overall sound of a home theater system. For example, a room con-sisting of hardwood floors and large expanses of glass can sound livelier,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. While EzSet/EQis making these adjustments a screen similar to the one shown inFigure 59 will appear. You may hear EzSet/EQ repeat tones from variousspeakers a number of times as it performs the equalization.Figure 59 – EzSet/EQ: EqualizationWhen EzSet/EQ has finished running all of these tests, a screen similarto the one in Figure 60 will appear. You may press the Set Button,and the Speaker Setup screen shown in Figure 52 will appear. Select“Manual Configuration” to view the settings resulting from EzSet/EQ.The manual Speaker Setup screens are explained in the AdvancedFunctions section.Figure 60 – EzSet/EQ: Successful ConfigurationConfigure SourcesIn the Installation section, you physically connected various cablesbetween your source devices and the AVR. In this section, you willassign the various audio and video inputs to their sources, ensuring thatthe AVR uses the correct connections each time you select a source.Press the OSD Button to view the menu system. The Input Setup menutab will be highlighted. Press the Set Button to select it, and the screenshown in Figure 61 will appear.Figure 61 – Input Setup Menu
