Surround Mode Selection
One of the most important features of the
AVR 8500 is its ability to reproduce a full multi- channel surround sound field from digital sources, analog matrix surround encoded pro- grams and standard stereo or even mono pro- grams.
Selection of a surround mode is based on personal taste, as well as the type of program source mate- rial being used. For example, CDs, motion pictures or TV programs bearing the logo of one of the major
When no rear speakers are in use, the Dolby 3 Stereo mode should be selected with all surround recordings.
Note that when Dolby Digital 2.0 signals (e.g. ”D.D. 2.0” tracks from DVD), that are encoded with Dolby Pro Logic information, are received via any digital input, the Dolby Pro Logic II Movie mode will be selected automatically (in addition to the Dolby Digital mode) and will decode a full range 5.1 channel surround sound even from those recordings (see also ”Dolby Digital” on page 35).
To create wide, enveloping sound field environ- ments and defined pans and flyovers with all analog stereo recordings select the Dolby Pro Logic II Music or Emulation mode or Harman Kardon’s exclusive Logic 7 Music mode for a dra- matic improvement in comparison to the Dolby Pro Logic (I) mode of former times.
NOTE: Once a program has been encoded with matrix surround information, it retains the sur- round information as long as the program is broadcast in stereo. Thus, movies with surround sound may be decoded via any of the analog sur- round modes such as Pro Logic II Cinema, Logic 7 Cinema or DTS Neo:6 Cinema, when they are broadcast via conventional TV stations, cable, pay- TV and satellite transmission. In addition, a grow- ing number of
Even when a program is not listed as carrying intentional surround information, you may find that the Dolby Pro Logic II Music, DTS NEO:6 Music or Logic 7 Music or Enhanced modes often deliver enveloping surround presentations through the use of the natural surround information pres- ent in all stereo recordings.
However, for stereo programs without any sur- round information the Theater, Hall and 5/7CH Stereo modes should be tried (effective particularly with old ”extreme” stereo recordings) and for mono programs, we suggest that you try the Theater or Hall modes. And when you use only two front channel speakers you should select Harman’s patented VMAx mode, delivering a virtu- ally three dimensional sound space with two speakers only.
Surround modes are selected using either the front panel controls or the remote. First deter- mine which of the surround mode categories you wish to choose from and press the button corre- sponding to that category: Dolby modes 5M or DTS Surround ÚNfrom digital sources, DTS Neo:6 & from analog sources, Logic

The THX modes involve specialized postprocess- ing techniques that optimize the audio signals after they have been decoded. Thus, when select- ing a THX mode, the AVR will automatically examine the signal to see whether it is analog or digital and apply Dolby Digital or DTS decoding if needed. The special THX circuits will then be acti- vated. To select a THX mode, press the Home THX button 6 on the front or remote and the proper THX mode for the active input will be activated. For further information on THX pro- cessing see surround mode table on page 30.

As the surround modes change, one or two green LEDs will light next to the current mode in the Surround Mode Indicators ¯list on the front panel.
Note that the Dolby Digital or DTS modes (except DTS Neo:6) may only be selected when a digital input is in use. In addition, when a digital source is present, the AVR will automatically select and switch to the correct mode (Dolby Digital or DTS), regardless of the mode that has been pre- viously selected. For more information on selecting digital sources, see the following section of this manual.

Depending on the number of speakers selected for your system configuration, you may also select a ”five channel stereo” or ”seven channel stereo” mode which places the
Note that no surround mode is available when an HDCD or MP3 source is being decoded.
Digital Audio Playback
Digital audio is a major advancement over older analog surround processing systems such as Dolby Pro Logic. It delivers five or six discrete channels: left front, center, right front, left surround and right surround and with DTS ES (see below) even sur- round back (with identical signals for left and right). Each channel reproduces full frequency range (20Hz to 20kHz) and offers dramatically improved dynamic range and significant improve- ments to
