34INITIAL SETUPFigure 53 – 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 characteristicsand speaker placement have on each speaker’s performance, and ofmaking adjustments to low-frequency response to compensate. WhileEzSet/EQ is making these adjustments a screen similar to the one shownin Figure 54 will appear. You may hear EzSet/EQ repeat tones fromvarious speakers a number of times as it performs the equalization.Figure 54 – EzSet/EQ: EqualizationWhen EzSet/EQ has finished running all of these tests, a screen similarto the one in Figure 55 will appear. You may press the Set Button, andthe Speaker Setup screen shown in Figure 47 will appear. Select “ManualConfiguration” to view the settings resulting from EzSet/EQ. The manualSpeaker Setup screens are explained in the Advanced Functions section.Figure 55 – 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 56 will appear.Figure 56 – Input Setup MenuThe first line indicates that the receiver is currently set to the DVDsource.Press the Set Button and then use the › Button to view the next source.The sources will be selected in the following order: Video 1, Video 2,Video 3, Video 4, HDMI 1, HDMI 2, 6CH Direct, 8CH Direct, DMP/TheBridge, Tape, CD, Tuner and XM. Pressing the ‹ Button selects thesources in the reverse order.For each of these sources, you may adjust the following settings. At aminimum, you should make sure that sources connected to any of thecomponent video or digital audio inputs have the correct settings. Othersettings are optional, and you may adjust them at a later time when youhave more experience with the AVR. Refer to the Table A4 worksheet inthe appendix that you filled out during installation as you assign inputsto each source.
