17AVR 158ENGLISHSet Up the AVR, continuedConfigure the AVR for Your SpeakersYour AVr is flexible and may be configured to work with most speakers and tocompensate for the acoustic characteristics of your room.before beginning, place your loudspeakers as explained in theplace Your Speakerssection, on page 10, and connect them to the AVr. consult the owner’s guide for thespeakers or the manufacturer’s web site for their frequency-range specification. Althoughyou may set the AVr’s individual channel levels “by ear,” an Spl (sound-pressure level)metre purchased at a local electronics store will provide greater accuracy.record your configuration settings in tables A4 and A6 in the Appendix for easy re-entryafter a system reset or after the AVr’s Master power switch has been turned off or theunit has been unplugged for more than four weeks.Step One – Determine Your Speakers’ Crossover Frequenciesconsult the technical specifications for all of your speakers and locate the frequencyresponse, usually given as a range, e.g., 100hz – 20khz (±3db). write down the lowestfrequency that each of your speakers is capable of playing (100hz in the above example)as the crossover in table A6 in the Appendix. NOTE: this frequency isnot the same asthe crossover frequency listed in the speaker’s specifications.For the subwoofer, write down the transducer size. the AVr’s bass managementdetermines which speakers will be used to play back the low-frequency (bass) portionof the source program. Sending the lowest notes to small satellite speakers will resultin bad sound and may even damage the speakers. the highest notes may not be heardat all through the subwoofer.with proper bass management, the AVr divides the source signal at a crossover point.All information above that crossover point is played through your system’s speakers,and all information below the crossover point is played through the subwoofer. this way,each loudspeaker in your system will perform at its best, delivering a more powerful andenjoyable sound experience.Step Two – Measure the Speaker DistancesIdeally, all of your speakers would be placed in a circle, with the listening position at thecentre. however, you may have had to place some speakers a little farther away from thelistening position than others. Sounds that are supposed to arrive simultaneously fromdifferent speakers may blur, due to different arrival times.Your AVr provides a distance adjustment that compensates for these real-worldspeaker-placement differences.Measure the distance from each speaker to the listening position, and write it downin table A4 in the Appendix. even if all of your speakers are the same distance fromthe listening position, enter your speaker distances as described inSet the Speakerdistances, on this page.Step Three – Speaker Setup Menunow you are ready to program the AVr. Sit in your usual listening position, and make theroom as quiet as possible.with the AVr and video display turned on, press the oSd button to display the menusystem and select Speaker Setup. the Speaker Setup menu will appear:* SPEAKER SETUP *NUMBER OF SPEAKERSSUB MODE : SUBCROSSOVERDISTANCELEVEL ADJUSTBACK TO MASTER MENUNOTE: All of the speaker setup submenus include a “back to…” option. to save thecurrent settings, select the back to… option.For best results, adjust the submenus in this order: number of Speakers, crossover, SubMode, distance and level Adjust.Number of Speakersthis selection lets you program the correct setting for each speaker group. the settingsin this menu affect the remainder of the speaker-setup process and the availability ofvarious surround modes at any time.Select on when the speakers are present in the system; select oFF for positions whereno speakers are installed. the Front left & right setting is always on and may not bedisabled.* NUMBER OF SPEAKERS *LEFT/RIGHT : ONCENTER : ONSURROUND : ONSUBWOOFER : ONBACK TO SPEAKER SETUPwhen you have finished, select back to Speaker Setup.Crossover (Size)After you return to the Speaker Setup menu, navigate to the crossover line and press theok button to display the crossover menu.* CROSSOVER *LEFT/RIGHT : 100HzCENTER : 100HzSURROUND : 100HzSUBWOOFER : 10inchBACK TO SPEAKER SETUPrefer to table A6 for each speaker’s crossover frequency.NOTE: the AVr will let you adjust settings only for those speaker groups you set to onin the number of Speakers menu.For each speaker group, select one of these eight crossover frequencies: lArge, 40hz,60hz, 80hz, 100hz, 120hz, 150hz or 200hz. If the speaker’s crossover frequency isbelow 40hz, select the first option, lArge. this setting doesn’t refer to the speaker’sphysical size but to its frequency response, which is also called “full range.”Specify the size of the subwoofer’s transducer as 8, 10, 12 or 15 inches. the AVr alwayssets the subwoofer crossover to 100hz but uses the transducer size for equalisation.write down the settings in table A6 in the Appendix.when you have finished entering the settings, select back to Speaker Setup.Sub ModeAfter you return to the Speaker Setup menu, navigate to the Sub Mode line and pressthe ok button to display the Sub Mode menu. this setting depends upon the crossoversetting you selected for the front left and right speakers.If you set the front speakers to a numeric crossover frequency, the subwoofer setting•will always be Sub. All low-frequency information will always be sent to the subwoofer.If you don’t have a subwoofer, either upgrade to full-range front left and right speakersor add a subwoofer at the earliest opportunity.If you set the front speakers to lArge, select one of the three following settings for•the subwoofer:l/r+lFe: this setting sends all low-frequency information to the subwoofer, includinga) information that would normally be played through the front left and right speakersand b) the special low-frequency effects (lFe) channel information.oFF: Select this setting when no subwoofer is in use. All low-frequency informationwill be sent to the front left and right speakers.lFe: this setting plays low-frequency information contained in the left and rightprogram channels through the front left and right speakers, and directs only the lFe-channel information to the subwoofer.when you have finished entering the settings, select back to Speaker Setup.Set the Speaker DistancesAs described above in Step two, when you measured the distances from each of yourspeakers to the listening position, your AVr provides an adjustment that compensatesfor the different distances so that the sound from each speaker will reach the listeningposition at the proper time. this process will improve the clarity and detail of thesound.
