SYSTEM CONFIGURATIONSYSTEM CONFIGURATION20 SYSTEM CONFIGURATION20 SYSTEM CONFIGURATIONIf the front left/right speakers are set to SMALL,the subwoofer will automatically be set to SUB,which is the “on” position.If the front left/right speakers are set to LARGE,three options are available:• If no subwoofer is connected to the AVR 230,press the ‹/› Buttons o on the remote sothat NONE appears in the on-screen menu.When this option is selected, all bass informationwill be routed to the front left/right “main” speakers.• If a subwoofer is connected and you wish to havethe front left/right “main” speakers reproduce bassfrequencies at all times, and have the subwooferoperate only when the AVR 230 is being usedwith a digital source that contains a dedicatedLow-Frequency Effects, or LFE, soundtrack. Pressthe ‹/› Buttons o on the remote so thatLFE appears in the on-screen menu.• If a subwoofer is connected and you wish to use itfor bass reproduction in conjunction with the mainfront left/right speakers, regardless of the type ofprogram source or Surround mode, press the ‹/›Buttons o on the remote so that SUBLFE+L/R appears in the on-screen menu.When this option is selected, a full-range signalwill be sent to the front left/right “main” speakers,and the subwoofer will receive the bass frequen-cies under frequency selected, as describedbelow, as well as the LFE information.When all initial speaker “size” settings have beenmade, you now have the option to take advantage ofthe AVR 230’s Triple Crossover system, which allowsindividual crossover settings to be made for eachspeaker grouping. The low-frequency crossover pointis set by the design of your speakers. Depending onthe design and driver complement of your speakers, itis defined as the frequency which is either the lowestpossible frequency the speaker is capable of repro-ducing, or the frequency at which sound is sent to thespeaker’s internal low-frequency driver, as opposed tothe mid-range driver. Before making any changes tothe settings for the crossover point, we suggest thatyou find the crossover point for the speakers in eachof the three groupings, front left/right, center and sur-rounds, by looking at the specifications page of eachspeakers’ owner’s manual, or by contacting your dealeror the manufacturer’s customer service departmentor Web site. You will need this figure to accuratelyconfigure the next group of settings.The factory default setting for all speaker positions is100Hz. If that setting is acceptable for all channels,then no adjustments are needed and you may skipthis section. However, should you wish to change oneof the settings, please proceed by pressing the ⁄Button n so that the cursor moves back up to thetop of the list of setting options. Press the ⁄/¤Buttons n so that X-OVER is highlighted andthe menu data will change to the screen shown inFigure 6.Figure 6To change the setting for any of the three speakergroups, press the ⁄/¤ Buttons n until the cursoris next to the line where you wish to make a changeand then press the ‹/› Buttons o until thedesired setting appears. The available choices at whichpoint low-frequency information will be sent to thesubwoofer, rather than to the main speaker channel,are 40Hz, 60Hz, 80Hz, 100Hz, 120Hz and 200Hz.Pick the choice that is identical to the information forthe speakers, or if an exact match is not possible, pickthe closest choice that is ABOVE the speaker’s low-frequency limit or crossover point to avoid the creationof a low-frequency “hole” where your system will haveno bass information.In cases where LARGE has been selected as thefront-channel speaker option and LFE+L/R hasbeen selected as the subwoofer option, the front-channel sound information below the setting shownwill be sent to BOTH the front-channel speakers andthe subwoofer. Note, also, that when the LARGE-LFE+L/R setting has been selected, thecrossover point is set by making adjustments at theSUBWOOFER line, but the setting for the frontleft/right speakers will automatically change in tandemso that the same setting appears for both speakerpositions. This ensures that there is no “hole” in thesound field due to different crossover points at thefront and subwoofer speakers.When all crossover settings have been made, or inthose cases where none are needed, press the ¤Button n so that the cursor is next to the BASSMGR line to make the final setting on this menu.This setting allows you to use the same speaker con-figuration, crossover settings and output levels for allinputs, or to have different settings for each input. Inmost cases the factory default setting of GLOBALwill be appropriate, as most listeners do not need tohave individualized settings. However, some listeners,particularly those with full-range front speakers that areused for both movies and music, may prefer that dif-ferent crossover points be used when listening tomusic through a CD player as opposed to a moviefrom a DVD player, VCR or cable/satellite set-top.If you wish to customize the speaker settings and out-put levels for each input, make certain that the cursoris on the BASS MGR line and press the ‹/›Buttons o so that INDEPENDENTappears. When this setting is entered by exiting themenu, you may need to go back to the INPUTmenu to select another input, and then return to thismenu page again to change the settings for thatinput. Repeat the procedure for any input where youwish to have a different set of speaker configurationand crossover settings.When all speaker selections have been made, pressthe ¤ Button n and then the Set Button p toreturn to the MASTER MENU.Delay SettingsDue to the different distances between the listeningposition for the front channel speakers and the sur-round speakers, the amount of time it takes for soundto reach your ears from the front versus surroundspeakers differs. You may compensate for this differ-ence through the use of the delay settings to adjustthe timing for the speaker placement and acousticconditions in your listening room or home theater.The AVR 230’s advanced software enables you toquickly and easily set delay times without the need tocalculate them using a complex formula. Instead, allyou need to do is measure the approximate distancebetween your listening position and each of thespeakers in your system. When you enter thosedistances into the AVR’s memory as shown below,the AVR’s microprocessor does the rest of the work,calculating the proper delay time. The measurementsneed not be accurate to the inch, as the system isdesigned to accommodate a typical listening arearather than require the precise measurement to one“sweet spot” position.Due to the differences in the way each surroundmode operates, some modes allow for a greater rangeof delay times than others. To avoid problems, werecommend that delay times be adjusted using theDolby Digital mode. If a different mode is selected ata later time, the AVR 230 will automatically restrictthe delay settings to those required by the surroundmode in use.* * S P E A K E R S E T U P * *M O D E : X - O V E RL E F T / R I G H T : 1 0 0 H ZC E N T E R : 1 0 0 H ZS U R R O U N D : 1 0 0 H ZS U R R B A C K : - - - - -S U B W O O F E R : S U B ( L F E )B A S S M G R : G L O B A LB A C K T O M A S T E R M E N U
