It provides up to five separate main audio channels and a special dedicated Low-Frequency Effects channel.Dolby Digital EXAvailable when the receiver is configured for 6.1/7.1-channel operation, Dolby Digital EX is the latest version of Dolby Digital.When used with movies or other programs that have special encoding, Dolby Digital EX reproduces specially encoded soundtracks so that a full 6.1/7.1 sound field is available.When the receiver is set for 6.1/7.1 operation and a Dolby Digital signal is present, the EX mode is automatically selected. Even if specific EX encoding is not available to provide the additional channel, the special algorithms will derive a 6.1/7.1 output.DTS 5.1When the speaker configuration is set for 5.1-channel operation, the DTS 5.1 mode is available when DVD, audio-only music or laser discs encoded with DTS data are played. DTS 5.1 provides up to five separate main audio channels and a special dedicated low-frequency channel.DTS-ES 6.1 MatrixWhen the speaker configuration is set for 6.1/7.1 operation, playback of a DTS-encoded program source will automatically trigger the selection DTS-ES 6.1 Discreteof one of the two DTS-ES modes. Newer discs with special DTS-ES discrete encoding will be decoded to provide six discrete, full-bandwidth channels plus a separate low-frequency channel.All other DTS discs will be decoded using the DTS-ES Matrix mode, which creates a 6.1-channel sound field from the original 5.1-channel soundtrack.Dolby Pro Logic IIDolby Pro Logic II is the latest version of Dolby Laboratorys benchmark surround technology that decodes full-range, discrete left, center right,Movieright surround and left surround channels from either matrix surround-encoded programs and conventional stereo sources when an analog input Musicis in use.The Dolby Pro Logic II Movie mode is optimized for movie soundtracks, while the Pro Logic II Music mode should be used with Pro Logicmusical selections.The Pro Logic mode activates original Pro Logic processing for those who prefer that presentation.Logic 7 CinemaExclusive to Harman Kardon for A/V receivers, Logic 7 is an advanced mode that extracts the maximum surround information from either Logic 7 Musicsurround-encoded programs or conventional stereo material. Depending on the number of speakers in use and the selection made in the Logic 7 EnhanceSURROUND SELECT menu, the “5.1” versions of Logic 7 modes are available when the 5.1 option is chosen, while the “7.1” versions of Logic 7 produce a full sound field presentation, including back surround speakers when the “6.1/7.1” option is chosen.The Logic 7 C (or Cinema) mode should be used with any source that contains Dolby Surround or similar matrix encoding. Logic 7 C delivers increased center-channel intelligibility, and more accurate placement of sounds with fades and pans that are much smoother and more realistic than with other decoding techniques.The Logic 7 M or Music mode should be used with analog or PCM stereo sources. Logic 7 M enhances the listening experience by presenting a wider front soundstage and greater rear ambience. Both Logic 7 modes also direct low-frequency information to the subwoofer (if installed and configured) to deliver maximum bass impact.The Logic 7 E (or Enhance) mode, available only when the 5.1 option is chosen,is an extension of the Logic 7 mode that is primarily used with musical programs. Logic 7 adds additional bass enhancement that circulates low frequencies in the 40Hz to 120Hz range to the front and surround speakers to deliver a less localized soundstage that appears broader and wider than when the subwoofer is the sole source of bass energy.DTS Neo:6 CinemaThese two modes are available when any analog source is playing to create a six-channel surround presentation from conventional Matrix-encoded DTS Neo:6 Musicand traditional Stereo sources. Select the Cinema version of Neo:6 when a program with any type of analog Matrix surround encoding is present.Select the Music version of Neo:6 for optimal processing when a nonencoded, two-channel stereo program is being played.Dolby 3 StereoUses the information contained in a surround-encoded or two-channel stereo program to create center-channel information. In addition, the information that is normally sent to the rear-channel surround speakers is carefully mixed in with the front-left and front-right channels for increased realism. Use this mode when you have a center channel speaker but no surround speakers.TheaterThe Theater mode creates a sound field that resembles the acoustic feeling of a standard live-performance theater.Hall 1, Hall 2The two Hall modes create sound fields that resemble a small (Hall 1) and medium-sized (Hall 2) concert hall.VMAx NearWhen only the two front-channel loudspeakers are used, Harmans patented VMAx mode delivers a three-dimensional sound space with the illusion VMAx Farof “phantom speakers” at the center and surround positions.The VMAx N, or “Near Field,” mode should be selected when your listening position is less than five feet from the speakers.The VMAx F, or “Far Field,” mode should be selected when your listening position is greater than five feet from the speakers.The VMAx modes are also available using the Headphones Output 4.When headphones are being used, the Far Field mode will appear to push the sound field away from your ears, reducing the “inside the head” sensation often experienced when using headphones.5-Channel StereoThis mode takes advantage of multiple speakers to place a stereo signal at both the front and back of a room. Depending on whether the AVR7-Channel Stereohas been configured for either 5.1 or 6.1/7.1 operation, one of these modes, but not both, is available at any time. Ideal for playing music in situations such as a party, it places the same signal at the front-left and surround-left, and front-right and surround-right speakers.The center channel is fed a summed mono mix of the in-phase material of the left and right channels.SurroundThis mode turns off all surround processing and presents the pure left- and right-channel presentation of two-channel stereo programs.Off (Stereo)TROUBLESHOOTING GUIDE 45TROUBLESHOOTING GUIDESYMPTOMCAUSESOLUTIONUnit does not function when Main No AC Power Make certain AC power cord is plugged into Power Switch is pusheda live outlet Check to see whether outlet is switch-controlledDisplay lights, but no sound Intermittent input connections Make certain that all input and speaker connections or pictureare secure Mute is on Press Mute Button Volume control is down Turn up volume controlUnit turns on, but front panel Display brightness is turned off Follow the instructions in the Display Brightness section display does not light upon page 28 so that the display is set to VFD FULLNo sound from any speaker; Amplifier is in protection mode Check speaker wire connections for shorts at receiver and light around power switch is reddue to possible shortspeaker ends Amplifier is in protection mode Contact your local Harman Kardon service centerdue to internal problemsNo sound from surround or Incorrect surround mode Select a mode other than Stereocenter speakers Input is monaural There is no surround information from mono sources Incorrect configuration Check speaker mode configuration Stereo or Mono program material The surround decoder may not create center- or rear-channel information from nonencoded programsUnit does not respond to Weak batteries in remote Change remote batteriesremote commands Wrong device selected Press the AVR selector Remote sensor is obscured Make certain front panel sensor is visible to remoteor connect remote sensorIntermittent buzzing in tuner Local interference Move unit or antenna away from computers, fluorescent lights, motors or other electrical appliancesLetters flash in the channel indicator Digital audio feed paused Resume play for DVDdisplay and digital audio stops Check that Digital Input is selectedIn addition to the items shown above, additional information on troubleshooting possible problems with your AVR 135, or installation-related issues, may be found in the list ofFrequently Asked Questions which is located in the Product Support section of our Web site at .41Processor ResetIn the rare case where the units operation or the dis-plays seem abnormal, the cause may involve the erraticoperation of the systems memory or microprocessor.To correct this problem, first unplug the unit from theAC wall outlet and wait at least three minutes. After thepause, reconnect the AC power cord and check theunits operation. If the system still malfunctions, a sys-tem reset may clear the problem.To clear the AVR 135s entire system memory includ-ing tuner presets, output level settings, delay times andspeaker configuration data, press and hold the ToneMode Button 5 button for three seconds.The unitwill turn on automatically.NOTE: Resetting the processor will erase any configu-ration settings you have made for speakers, outputlevels, surround modes, digital input assignments aswell as the tuner presets.The unit will be returned tothe factory presets, and all settings for these itemsmust be reentered.If the system is still operating incorrectly, there mayhave been an electronic discharge or severe AC lineinterference that has corrupted the memory ormicroprocessor.If these steps do not solve the problem, consult anauthorized Harman Kardon service center.AMPLIFIER SECTION BIAS ADJUSTMENTCUP11651Y (BIAS PCB)Measurement condition.
