Speaker/Channel IndicatorsIn addition to the bitstream indicators, the AVR 335features a set of unique channel-input indicators thattell you how many channels of digital information arebeing received and/or whether the digital signal isinterrupted (see Figure 12).Figure 12These indicators are the L/C/R/LFE/SL/SR/SBL/SBRletters that are inside the center boxes of the Speaker/Channel Input Indicators ˆ on the front panel.When a standard analog signal is in use, only the “L”and “R” indicators will light, as analog signals have onlyleft and right channels.Digital signals, however, may have two, five, six orseven channels, depending on the program material,the method of transmission and the way in which itwas encoded. When a digital signal is playing, the let-ters in these indicators will light in response to thespecific signal being received. It is important to notethat although Dolby Digital, for example, is referredto as a “5.1” system, not all Dolby Digital DVDs orprograms are encoded for 5.1. Thus, it is sometimesnormal for a DVD with a Dolby Digital soundtrack totrigger only the “L” and “R” indicators.NOTE: Many DVD discs are recorded with both “5.1”and “2.0” versions of the same soundtrack. Whenplaying a DVD, always be certain to check the type ofmaterial on the disc. Most discs show this informationin the form of a listing or icon on the back of the discjacket. When a disc does offer multiple soundtrackchoices, you may have to make some adjustments toyour DVD player (usually with the “Audio Select” buttonor in a menu screen on the disc) to send a full 5.1feed to the AVR 335. It is also possible for the type ofsignal feed to change during the course of a DVDplayback. In some cases, the previews of specialmaterial will only be recorded in 2.0 audio, while themain feature is available in 5.1 audio. The AVR 335will automatically sense changes to the bitstream andchannel count and reflect them in these indicators.Night ModeA special feature of Dolby Digital is the Night mode,which enables specially encoded Dolby Digital inputsources to be played back with full digital intelligibilitywhile reducing the minimum peak level by 1/4 to 1/3.This prevents abruptly loud transitions from disturbingothers, without reducing the impact of the digitalsource. The Night mode is available only when DolbyDigital signals with special data are being played.The Night mode may be engaged when a DolbyDigital DVD is playing by pressing the Night ModeButton l on the remote. Next, press the ⁄/¤Buttons n to select either the middle range orfull-compression versions of the Night mode. To turnthe Night mode off, press the ⁄/¤ Buttons nuntil the message in the lower third of the video dis-play and in the Lower Display Line ¯ readsD-RANGE OFF.The Night mode may also be selected to always be onat either level of compression using the options in theDOLBY menu. See page 19 for information onusing the menus to set this option.IMPORTANT NOTES ON DIGITAL PLAYBACK:• Although the AVR 335 will decode virtually all currentDVDs, CDs and HDTV sources, it is possible that somefuture digital sources may not be compatible with it.• Not all digitally encoded programs contain full 5.1-or 6.1-channel audio. Consult the program guidethat accompanies the DVD or laser disc to deter-mine which type of audio has been recorded on thedisc. The AVR 335 will automatically sense the digi-tal surround encoding used and accommodate it.• When a digital source is playing, you may not beable to select some of the analog surround modessuch as Dolby Pro Logic II, Dolby 3, Stereo, Hall,Theater or Logic 7.• When a Dolby Digital or DTS source is playing,it is not possible to make an analog recording usingthe Tape Outputs £ and Video 1 or Video 2Audio Outputs . However, the digital signalswill be passed through to the Digital AudioOutputs ab.PCM Audio PlaybackPCM (Pulse Code Modulation) is the noncompresseddigital audio system used for compact discs and laserdiscs. The digital circuits in the AVR 335 are capable ofhigh-quality digital-to-analog decoding, and they maybe connected directly to the digital audio output of yourCD or LD player.Connections may be made to either the rear-panelOptical or Coaxial Inputs dg or the front-panelDigital Inputs *(.To listen to a PCM digital source, first select the input forthe desired source (e.g., CD). Next press the DigitalSelect Button #q and then use the ⁄/¤Buttons n on the remote, or the ‹/› SelectorButtons ) on the front panel, until the desired choiceappears in the Upper Display Line ˜.During PCM playback, you may select any Surroundmode except Dolby Digital or DTS.Tuner OperationThe AVR 335’s tuner is capable of tuning AM, FM andFM Stereo broadcast stations. Stations may be tunedmanually, or they may be stored as favorite station pre-sets and recalled from a 30-position memory.Station Selection1. Press the AM/FM Tuner Select Button gçto select the tuner as an input. The tuner may beselected from the front panel by either pressing theInput Source Selector ^ until the tuner is activeor by pressing the AM/FM Band Selector !.2. Press the AM/FM Tuner Select Button gçor AM/FM Band Selector ! again to switchbetween AM and FM so that the desired frequencyband is selected.3. Press the Tuner Mode Button & s to selectmanual or automatic tuning.When the button is pressed so that AUTOappears in the Lower Display Line ¯ eachpress of the Tuning Selectors 9u é will putthe tuner in a scan mode that seeks the next higheror lower frequency station with acceptable signalstrength. An AUTO ST TUNED indicationwill momentarily appear when the station stopsat a stereo FM station, and an AUTO TUNEDindication will momentarily appear when an AMor monaural FM station is tuned. Press the Tuningbuttons again to scan to the next receivable station.When the button is pressed so that MANUALappears in the Lower Display Line ¯ each tapof the Selector will change the frequency by oneincrement. When the tuner receives a strong enoughsignal for reception, MANUAL TUNED willappear in the Lower Display Line ¯.4. Stations may also be tuned directly in either theautomatic or manual mode. To enter a station’s fre-quency directly, first select the AM or FM band asdesired be pressing the AM/FM Tuner SelectButton g!. Next, press the Direct Buttont.
