42ADVANCED FUNCTIONSare unable to run EzSet/EQ II calibration, or if you wish to makefurther adjustments, use the Manual Speaker Setup on-screenmenus.Before beginning, place your loudspeakers as explained in theSpeaker Placement section, and connect them to the AVR. Consultthe owner’s guide for the speakers or the manufacturer’s Web sitefor the frequency range specification. Although you may set the out-put levels “by ear,” an SPL (sound-pressure level) meter purchasedat a local electronics store will provide greater accuracy.Record your configuration settings in Tables A3 through A12 in theappendix for easy re-entry after a system reset, or if the AVR’sMaster Power Switch is turned off or the unit is unplugged formore than four weeks.NOTE: When using the AVR’s Speaker Setup menus, selecta video output resolution of 720p or higher to view graphicsthat simplify configuration.STEP ONE – Determine SpeakerCrossoverWithout using the EzSet/EQ II process, the AVR 7550HD can’t detecthow many speakers you’ve connected to it; nor can it determinetheir capabilities. Consult the speaker’s technical specificationsand locate the frequency response, usually given as a range, e.g.,100Hz – 20kHz (±3dB). Write down the lowest frequency that eachof your main speakers is capable of playing (100Hz in the example)as the crossover in Table A3 in the appendix. This is not the sameas the crossover frequency listed in the speaker’s specifications.For the subwoofer, write down the transducer size.The receiver’s bass management determines which speakers willbe used to play back the low-frequency (bass) portion of the sourceprogram. Sending the lowest notes to small satellite speakers won’tsound right, and may even damage the speaker. The highest notesmay not be heard at all through the subwoofer.With proper bass management, the AVR 7550HD divides the sourcesignal at a crossover point. All information above the crossoverpoint is played through the satellite speaker, and all informationbelow the crossover point is played through the subwoofer. Eachloudspeaker in your system performs at its best, delivering anenjoyable sound experience.STEP TWO – Measure Speaker DistancesIdeally, all of your speakers would be placed in a circle, with thelistening position at the center. However, you may have had to placesome speakers a little further away from the listening position thanothers. Sounds that are supposed to arrive simultaneously fromdifferent speakers may blur, due to different arrival times.Use the AVR’s delay adjustment to compensate for real-worldspeaker placements.Measure the distance from each speaker to the listening position,and write it down in Table A4 in the appendix. Even if all of yourspeakers are the same distance from the listening position, enteryour speaker distances as described in Step Three.STEP THREE – Manual Setup MenuNow you are ready to program the receiver. Sit in the usual listeningposition and make the room as quiet as possible.With the receiver and video display turned on, press the AVRSettings Button to display the menu system. Use the 5 Button tomove the cursor to the Speaker Setup line, and press the OK Buttonto display the Speaker Setup menu. See Figure 21.If you have run the EzSet/EQ II process, the results were savedin one of the two listening positions. Adjust the Speaker Setupsetting in the Audio Effects menu to activate the results for eitherposition (see page 45). To tweak the EzSet/EQ II results, or to con-figure the AVR from scratch, select Setup Listening Position 1 orSetup Listening Position 2. A screen similar to the one shown inFigure 28 will appear.Figure 28 – Speaker Setup Position MenuNOTE: All of the speaker setup submenus include the Backoption, as shown at the bottom of Figure 28. To save the currentsettings, select the Back option.To reconfigure the speakers from scratch, select the Reset option.For best results, adjust the submenus in this order: Number ofSpeakers, Crossover (Size), Sub Mode, Distance and Level Adjust.Number of SpeakersMove the cursor to the Number of Speakers line and press theOK Button. See Figure 29.Figure 29 – Number of Speakers MenuProgram the correct setting for each speaker group: ON when thespeakers are present in the system, and OFF for positions where nospeakers are installed. The Front Left & Right speakers are alwaysON and may not be disabled. Any changes will be reflected in thetotal number of speakers displayed at the top of the screen.The setting for the surround back speakers includes a third option:Zone 2. The AVR 7550HD is capable of multizone operation, supportingplacement of a pair of speakers in another room. The AVR 7550HD’sassignable surround back amplifier channels make multizone operation
