30 OPERATIONOperationControls and Use of Headphones• Adjust the volume to a comfortable level usingthe front panel Volume Control ı or remoteVolume Up/Down )î buttons.• To temporarily silence all speaker outputs pressthe Mute button , ˚. This will interrupt theoutput to all speakers and the headphone jack,but it will not affect any recording or dubbingthat may be in progress. When the system ismuted, the word MUTE will blink in the MainInformation Display ˜. Press the Mutebutton , ˚ again to return to normaloperation.• During a listening session you may wish toadjust the Bass Control and TrebleControl Ú to suit your listening tastes or roomacoustics. Note that these controls (and Balance)will not function when the 6/8 channel directinput is in use.• To set the output of the AVR so that the outputis “flat,” with the tone and balance controls de-activated, press the Tone Mode button 8 onceor twice so that the words Tone Out appearmomentarily in the Main Information Display˜. To return the tone controls to an active con-dition, press the Tone Mode 8 button once ortwice so that the words Tone I n momentarilyappear in the Main Information Display ˜.• For private listening, plug the 6.3 mm stereophone plug from a pair of stereo headphonesinto the front panel Headphone Jack 4. Notethat when the headphone’s plug is connected,the word HEADPHONE will scroll once acrossthe Main Information Display ˜ and allspeakers will be silenced. When the headphoneplug is removed, the audio feed to the speakerswill be restored.Surround Mode SelectionOne of the most important features of theAVR 330 is its ability to reproduce a full multi-channel surround sound field from digitalsources, analog matrix surround encodedprograms and standard stereo or even monoprograms. In all, a total of 23 listening modes areavailable on the AVR.Selection of a surround mode is based on personaltaste, as well as the type of program source mate-rial being used. For example, CDs, motion picturesor TV programs bearing the logo of one of themajor surround-encoding processes, such as DolbySurround should be played in either the Dolby ProLogic II Movie (with movies) or Music (withmusic) surround mode, with any DTS NEO:6mode or with Harman Kardon´s exclusive Logic 7Movie Mode, to create a full range 5.1 channelor (with Logic 7 and DTS NEO:6) even 7.1channel surround signal from surround encodedprograms, with a stereophonic left and right rearsignal, just as it was recorded (e.g. sound beingrecorded from left rear side will be heard fromthat side only, for more details see chart onpage 27).When no rear speakers are in use, the Dolby 3Stereo mode should be selected with all surroundrecordings.Note that when Dolby Digital 2.0 signals (e.g."D.D. 2.0" tracks from DVD), that are encodedwith Dolby Pro Logic information, are receivedvia any digital input, the Dolby Pro Logic II Moviemode will be selected automatically (in additionto the Dolby Digital mode) and will decode a fullrange 5.1 channel surround sound even fromthose recordings (see also "Dolby Digital" onpage 31).To create wide, enveloping sound field environ-ments and defined pans and flyovers with allanalog stereo recordings select the Dolby ProLogic II Music or Emulation mode or HarmanKardon’s exclusive Logic 7 Music mode for adramatic improvement in comparison to theDolby Pro Logic (I) mode of former times.NOTE: Once a program has been encoded withmatrix surround information, it retains the sur-round information as long as the program isbroadcast in stereo. Thus, movies with surroundsound may be decoded via any of the analog sur-round modes such as Pro Logic II Cinema, Logic 7Cinema or DTS Neo:6 Cinema, when they arebroadcast via conventional TV stations, cable,pay-TV and satellite transmission. In addition, agrowing number of made-for-television programs,sports broadcasts, radio dramas and music CDsare also recorded in surround sound. You mayview a list of these programs at the DolbyLaboratories Web site at www.dolby.com.Even when a program is not listed as carryingintentional surround information, you may findthat the Dolby Pro Logic II Music, DTS NEO:6Music or Logic 7 Music or Enhanced modes oftendeliver enveloping surround presentations throughthe use of the natural surround informationpresent in all stereo recordings.However, for stereo programs without anysurround information the Theater, Hall and 5/7CHStereo modes should be tried (effective particularlywith old ”extreme” stereo recordings) and formono programs, we suggest that you try theTheater or Hall modes. And when you use onlytwo front channel speakers you should selectHarman’s patented VMAx mode, delivering avirtually three dimensional sound space with twospeakers only.Surround modes are selected using either thefront panel controls or the remote. To select anew surround mode from the front panel, firstpress the Surround Mode Group SelectorButton 5 until the desired major surroundmode group such as Dolby, DTS or Logic 7 isselected. Next, press the Surround ModeSelector Button 9 to choose the specificindividual surround mode.To select a surround mode using the remote con-trol, press the button for the major surroundmode group that includes the mode you wish tochoose from: Dolby M, DTS Surround N,DTS Neo:6 , Logic 7 O, Stereo orDSP Surround A. The first press of the buttonwill show the current mode from that group if itis already in use, or the first available mode if youare currently using another mode. To cyclethrough the available modes in that group pressthe button again until the desired mode appearsin the Main Information Display ˜ and theon-screen display.To select from the DSP modes (Hall 1, Hall 2,Theater, VMAx Near or VMAx Far) press theSurround Mode Selector A repeatedly toscroll through the list of available modes.As the surround modes change, a blue LED willlight next to the current mode in the SurroundMode Indicators ( list on the front panel.Note that the Dolby Digital or DTS modes mayonly be selected when a digital input is in use. Inaddition, when a digital source is present, theAVR will automatically select and switch to thecorrect mode (Dolby Digital or DTS), regardless ofthe mode that has been previously selected. Formore information on selecting digital sources, seethe following section of this manual.When the 6-Channel/8-Channel direct inputs arein use there is no surround processing, as theseinputs take the analog output signals from anoptional, external DVD-Audio or SACD player, oranother source device and carry them straightthrough to the volume control.
