33INITIAL SETUPFigure 50 – EzSet/EQ: Warning to Plug in MicrophoneNOTE: As shown in Figures 48, 49, and 51–54, while EzSet/EQis in progress a Cancel setting is available or even highlighted. Youmay interrupt EzSet/EQ at any time by selecting the Cancel settingand pressing the Set Button.What EzSet/EQ DoesEzSet/EQ will send test signals to the various speakers and performthe measurements described in this section, adjusting the AVR 247’ssettings to match EzSet/EQ’s internal references.Set Master Volume Level: EzSet/EQ sends test tones to the frontspeakers and adjusts the system’s volume level to enable it to take theremaining measurements correctly. EzSet/EQ uses the left front speakerto set the master volume level, and then it proceeds directly to measuringthe speaker output levels.Speaker Level: During this test, EzSet/EQ ensures that all speakerssound equally loud at the listening position. During a surround soundpresentation it is common for the surround channels to sound lessprominent, or not to be used at all at times. By setting the baselinechannel levels correctly, the AVR serves as a blank canvas for themovie director to create special effects.A screen similar to the one shown in Figure 51 will appear, with thespeaker position changing as EzSet/EQ measures the levels for eachspeaker. You may occasionally hear EzSet/EQ send a tone back to thefront left speaker. This enables EzSet/EQ to compare the level of thespeaker being measured to the reference level it set for the front leftspeaker.Figure 51 – EzSet/EQ: Speaker Level TestIf at any time the test tone is not heard from the speaker indicated onscreen, press the Set Button to stop EzSet/EQ. Turn off the AVR usingthe Master Power Switch and check your speaker connections. Makesure all wires are connected to the correct speakers and SpeakerOutputs on the AVR, and that you have observed the correct polarity(+ terminals connected to + terminals, and – terminals connected to– terminals).NOTE: EzSet/EQ can only detect the presence of a speaker,not its location within the room. If your speakers are not placedreasonably close to the positions shown in Figures 15 or 16 inthe Speaker Placement Section, then EzSet/EQ may not be ableto perform this test correctly.If EzSet/EQ detects only one speaker in a pair (e.g., surround back leftbut no surround back right or no main speakers), it will generate anerror and stop. If that happens, check that you have placed your speakersin their correct locations, and that you have wired each speaker to itscorrect set of speaker terminals.Speaker Distance: During this test, EzSet/EQ measures the distancefrom each speaker to the listening position. If the speakers are placedat different distances from the listener, the sound from speakers placedcloser needs to be delayed so that it reaches the listener at the sametime as the sounds from the other speakers. This preserves the clarityand directionality of surround sound presentations. During the SpeakerDistance test a screen similar to the one shown in Figure 52 will appear.The speaker position will change as EzSet/EQ measures the distancefor each speaker.Figure 52 – EzSet/EQ: Speaker Distance TestNOTE: The AVR 247 is also capable of setting a different typeof delay, called A/V Sync Delay, which is used to compensatefor lip sync problems that may occur when a video displaydevice or set-top box causes delays while digital video signalsare processed. It simultaneously adds a delay to all speakerchannels in the system. A/V Sync Delay is not set duringEzSet/EQ. It may be set while watching a program as follows:press the Delay Button on the remote and the first settingdisplayed is A/V Sync Delay. Press the Set Button to select itand 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 53 will appear,with the speaker position changing as each speaker is measured.
