Figure 6If the Dolby Digital mode is selected, theCENTER DELAY line is where the firstadjustment is made. In that case, press the ‹/›Buttons o until the number calculatedusing the formula shown above appears in thedisplay. When the CENTER DELAY isentered, press the ¤ Button n once tomove to the next line.When the CENTER DELAY is set, or ifthe Dolby Pro Logic II mode is selected, the ›cursor will be at the SURR DELAY line sothat the delay for the surround speakers maybe set. Press the ‹/› Buttons o untilthe number calculated using the formulashown above appears in the display. When thedelay settings are complete, press the ¤Button n once so that the cursor is next tothe BACK TO MASTER MENU line andpress the Set Button p to return to theMASTER menu.Output Level AdjustmentOutput level adjustment is a key part of theconfiguration of any surround-sound product. Itis particularly important for a digital receiversuch as the AVR 320, as correct outputs ensurethat you hear sound tracks with the properdirectionality and intensity.IMPORTANT NOTE: Listeners are often con-fused about the operation of the surroundchannels. While some assume that soundshould always be coming from each speaker,most of the time there will be little or nosound in the surround channels. This isbecause they are only used when a moviedirector or sound mixer specifically placessound there to create ambience, a specialeffect or to continue action from the front ofthe room to the rear. When the output levelsare properly set, it is normal for surroundspeakers to operate only occasionally.Artificially increasing the volume to the rearspeakers may destroy the illusion of anenveloping sound field that duplicates the wayyou hear sound in a movie theater or concert hall.Before beginning the output level adjustmentprocess, make certain that all speaker connec-tions have been properly made. The systemvolume should be set to the level that you willuse during a typical listening session. Finally,make certain that the Balance Control Ò isset to the center “12 o’clock” position.Using EzSetHarman Kardon’s exclusive EzSet remote makesit possible to quickly and accurately set theAVR 320’s output levels without the use of asound pressure meter, although manual adjust-ment is also available. However, for the easiestset-up, follow these steps while seated in thelistening position that will be used most often:1. Make certain that all speaker positionshave been properly configured for their“large” or “small” settings (as outlinedabove) and turn off the OSD system if it isin use.2. Adjust the volume so that it is at -15, asshown in the on-screen display or MainInformation Display Y.3. Hold the remote in front of you at arm’slength, being sure not to cover the EzSetSensor Microphone at the top ofthe remote.4. Press and hold the SPL Indicator SelectButton for three seconds. Release itwhen the Program/SPL Indicator cstops flashing and and remains lit. Withinfive seconds, press the “5” Numeric Keyr on the remote if your system is config-ured for 5.1 operation with standardspeakers or the “7” Numeric Key r onthe remote if your system is configured for6.1/7.1 operation with a full speaker com-plement including rear surround speakers.Once the correct channel configurationbutton has been pressed the test noise willbe heard from the front left speaker.5. At this point, EzSet will take over, adjustingthe output level of each channel so thatwhen the process is complete all levels willbe equal and at the set reference point.This process may take a few minutes,depending on the extent of adjustmentrequired.6. During the adjustment, you will see thelocation of the channel position beingadjusted appear in the on-screendisplay (if connected) in the MainInformation Display Y, alternatingwith a readout of the output setting, rela-tive to the reference volume level, and inthe Speaker/Channel Input IndicatorsQ where the letters for the channel beingadjusted will flash to indicate from whichchannel the test tone should be heard. Asthe adjustment proceeds, a few things willhappen simultaneously:• The channel position being adjusted willflash in the Speaker/Channel InputIndicators Q. If the test noise is heardfrom a channel other than the one shownin the Indicator, there is an error in thespeaker connections. If this is the case,press the Test Button i TWICE tostop the adjustment. Then, turn the unitoff and verify that all speakers are con-nected to the proper Outputsnop and that any connectionsmade to rear surround speakers poweredby optional amplifiers through thePreamp Outputs are correct.• As the individual channels are set, thechannel name and the adjustment offsetwill appear in the on-screen display (ifconnected) and the Main InformationDisplay Y. While the level is changing,the Program/SPL Indicator c willchange colors to reflect the output levelin relation to the reference. A red indica-tion shows that the level is too high,while an amber indication shows that thelevel is too low. When the indicator isgreen, the level is correct, and the testnoise will move to the next channel.• While adjustments are being made, thered LED under the AVR Selector fwill flash. This is normal, and indicatesthat EzSet is operating.7. After the test noise has circulated oncethrough each channel, it will send the toneto each channel once again, to verify thesettings.8. After two complete circulations of thetone, the levels are set. The Program/SPLIndicator c will remain green at eachchannel. Upon completion of the secondcirculation, the Program/SPL Indicatorc will flash green twice and then goout. The tone will stop and the AVR 320will return to normal operation.If you find that the output levels chosen byEzSet are either uncomfortably low or high, youmay repeat the procedure. Return to Step 2 andadjust the master volume either slightly higheror lower to accommodate your particular roomlayout and your tastes.
