OPERATIONOPERATION 33• For private listening, simply place a standard1/4" stereo headphone plug or adaptor into theHeadphone Jack B behind the door 9 on thefront panel. The speakers will automatically muteand a two-channel stereo signal will be sent to theheadphones. The Lower Display Line $ will readDOLBY H: BP, indicating that the headphoneoutput is in the Bypass mode, and to confirm thatno processing is being used.• When the headphones are in use, you may takeadvantage of the Dolby Headphone modes to bringadded spaciousness to headphone listening. Pressthe Dolby Mode Select Button g or theSurround Mode Selector 3 to cycle through thethree Dolby Headphone modes to select the onethat you prefer.Surround Mode SelectionOne of the most important features of the AVR 435is its ability to reproduce a full multichannel surroundsound field from digital sources, analog matrixsurround-encoded programs and standard stereoprograms.Selection of a surround mode is based on personaltaste, as well as the type of program source materialbeing used. For example, motion pictures or TV pro-grams bearing the logo of one of the major surround-encoding processes, such as Dolby Surround or DTSStereo may be played in either the Dolby Digital,Dolby Pro Logic II Cinema, DTS Neo:6 Cinema, orLogic 7 Cinema surround modes, depending on thesource material.NOTE: Once a program has been encoded with matrixsurround information, it retains the surround informationas long as the program is broadcast in stereo. Thus,movies with surround sound may be decoded via anyof the analog surround modes such as Pro Logic IICinema, Logic 7 Cinema or DTS Neo:6 Cinema, whenthey are broadcast via conventional TV stations, cable,pay-TV and satellite transmission. In addition, a growingnumber of made-for-television programs, sports broad-casts, radio dramas and music CDs are also producedin surround sound. You may view a list of these pro-grams at the Dolby Laboratories Web site atwww.dolby.com.Even when a program is not listed as carrying intentionalsurround information, you may find that the Pro Logic II,Pro Logic IIx, Logic 7 or DTS Neo:6, and the Hall orTheater modes often deliver enveloping surround pre-sentations through the use of the natural informationpresent in all stereo recordings.Surround modes may be changed at any time byusing either the front panel or remote control. Toselect a new surround mode from the front panel, firstpress the Surround Mode Group Selector Button2 until the desired major surround mode group suchas Dolby, DTS or Logic 7 is selected. Next, press theSurround Mode Selector Button 3 to choose thespecific individual surround mode.To select a surround mode using the remote, pressthe button for the major surround mode group thatincludes the mode you wish to choose from: Dolbyg, DTS Digital f, DTS Neo:6 e, Logic 7h, Stereo d or DSP Surround g. The firstpress of the button will show the current mode fromthat group if it is already in use, or the first availablemode if you are currently using another mode. Tocycle through the available modes in that group,press the button again until the desired mode appearsin the Lower Display Line $ and the on-screendisplay and in the front-panel Surround ModeIndicators %.The Dolby Digital, Dolby Digital EX, DTS 5.1, DTS-ESMatrix and DTS-ES Discrete modes may only beselected when a digital input is in use. In addition,when a digital source is present, the AVR 435 willautomatically select and switch to the correct mode,regardless of the mode that has been previouslyselected. For more information on selecting digitalsources, see the Digital Audio Playback section below.When the 6-Channel/8-Channel direct inputs are inuse, there is no surround processing, as these inputstake the analog output signals from an optional, exter-nal DVD-Audio or SACD player, or another sourcedevice and carry them straight through to the volumecontrol without any further digital processing.To listen to a program in traditional two-channelstereo, using the front left and front right speakersonly (plus the subwoofer, if installed and configured),press the Stereo Mode Select Button untilSURROUND OFF appears in the Lower DisplayLine $. From the front panel, press the SurroundMode Group Selector 2 until the Stereo modesappear in the on-screen display and Lower DisplayLine $. Next, press the Surround Mode SelectorButton 3 until SURROUND OFF appears inthe on-screen display and Lower Display Line $.Digital Audio PlaybackDigital audio is a major advancement over older analogsurround processing systems. It delivers up to six dis-crete channels, and each channel reproduces full fre-quency range (20Hz to 20kHz) and offers dramaticallyimproved dynamic range and significant improvements tosignal-to-noise ratios. In addition, digital systems have thecapability to deliver an additional channel that is specifi-cally devoted to low-frequency information. This is the“.1” channel referred to when you see these systemsdescribed as “5.1,” “6.1” or “7.1.” The bass channel isseparate from the other channels, but since it is inten-tionally bandwidth-limited, sound designers have given itthat unique designation. When a Digital soundtrack isplaying, the number of channels available will varyaccording to the way in which the program wasrecorded. Although most movies recorded with digitalsound have 5.1 soundtracks, some have 6.1 or 7.1sound, while others retain the original 2.0 or evenmonaural sound. When the program source is abroadcast, cable or satellite delivered digital program,only one type of soundtrack may be delivered at atime, while optical sources such as DVD may providemore than one audio option. In either case, the deci-sion of what type of sound track and how many chan-nels to offer is up to the program’s producer. With theAVR 435 you are able to not only play back the origi-nal compatible digital format, but using the processingpower of the Texas Instruments DSP processor it ispossible to decode the basic digital track for 2.0 or5.1 sound and then select an additional “post-pro-cessing” mode to deliver additional channels.Dolby DigitalDolby Digital is a standard part of DVD, and is availableon specially encoded LD discs and satellite broad-casts and it is a part of the high-definition television(HDTV) system.An optional, external RF demodulator is required touse the AVR 435 to listen to the Dolby Digital sound-tracks available on laser discs. Connect the RF outputof the LD player to the demodulator and then connectthe digital output of the demodulator to the Optical orCoaxial Inputs KM of the AVR 435. Nodemodulator is required for use with DVD players orDTS-encoded laser discs.In order to provide maximum playback compatibilitywith DVDs, the AVR 435 receiver will always defaultfirst to the playback mode embedded in a disc’s digital“flag” information. For Dolby Digital discs, the followingplayback modes are initially selected after the AVRlocks to the incoming digital audio data stream toidentify the selected:• When a 5.1 audio stream is detected, the DolbyDigital 5.1 format will be selected, regardless of thenumber of speakers in your system, in compliancewith Dolby Laboratories licensing requirements.• When a disc with the Dolby Digital EX format flag isplayed, your system will automatically switch to theEX mode when seven main channel speakers areavailable.3334353637383940414849464744454243383940413132302829252627282930242322212031373635343332 31373635343332484950514746454443423334353637383940414849464744454243383940413132302829252627282930242322212031373635343332 31373635343332484950514746454443423334353637383940414849464744454243383940413132302829252627282930242322212031373635343332 3137363534333248495051474645444342Continued on page 35
