Operation

Note that when the 6-Channel or 8-Channel Input is in use, you may not select a surround mode, as the external decoder determines the processing in use. In addition, there is no signal at the record outputs or bass management when the 6-Channel or 8-Channel Direct Input is in use and the tone or balance controls will not function.

Controls and Use of Headphones

•Adjust the volume to a comfortable level using the front panel Volume Control ı or remote

Volume Up/Down

I buttons.

•To temporarily silence all speaker outputs press the Mute button K. This will interrupt the output to all speakers and the headphone jack, but it will not affect any recording or dubbing that may be in progress. When the system is muted, the word MUTE will blink in the Main Information Display ˜. Press the Mute button K again to return to normal operation.

•During a listening session you may wish to adjust the Bass Control and Treble Control to suit your listening tastes or room acoustics. Note that these controls (and Balance) will not function when the 6/8 channel direct input is in use.

•To set the output of the AVR so that the output is “flat,” with the tone and balance controls deactivated, press the Tone Mode button 8

once or twice so that the words Tone Out appear momentarily in the Main Information Display ˜. To return the tone controls to an active condition, press the Tone Mode 8 button once or twice so that the words Tone In momentarily appear in the Main Information Display ˜.

•When the tone controls are active, the amount of bass and treble boost/cut may be adjusted by first pressing the Tone Mode Button on the

front panel 8 or the remote two or three times until the desired setting (BASS MODE or TREBLE MODE) appears in the on-screen display and the Lower Display Line ˜. Next, use the ⁄/¤ Navigation Button E on the remote or the ‹/› Button on the front panel

7$ to change the setting as desired. The unit will return to normal operation within five seconds after the setting is changed.

•For private listening, plug the 6.3 mm stereo phone plug from a pair of stereo headphones into the front panel Headphone Jack 4.

Note that when the headphone’s plug is con- nected, the speakers will automatically mute and a two-channel stereo signal will be sent to the headphones. The Lower Display Line ˜ will read DOLBY H: BP, indicating that the headphone output is in the Bypass mode, and to confirm that no processing is being used.

•When the headphones are in use, you may take advantage of the Dolby Headphone modes to bring added spaciousness to headphone listen- ing. Press the Dolby Mode Select Button M or the Surround Mode Group Selector 5 to cycle through the three Dolby Headphone modes to select the one that you prefer.

Surround Mode Selection

One of the most important features of the AVR is its ability to reproduce a full multichannel surround sound field from digital sources, analog matrix surround encoded programs and standard stereo or even mono programs.

Selection of a surround mode is based on personal taste, as well as the type of program source material being used. For example, CDs, motion pictures or TV programs bearing the logo of one of the major surround-encoding processes, such as Dolby Surround should be played in either the Dolby Pro Logic II Movie (with movies) or Music (with music) surround mode, with any DTS NEO:6 mode or with Harman Kardon´s exclusive Logic 7 Movie Mode, to create a full range 5.1 channel or (with Logic 7 and DTS NEO:6) even 7.1 channel surround signal from surround encoded programs, with a stereophonic left and right rear signal, just as it was recorded (e.g. sound being recorded from left rear side will be heard from that side only, for more details see chart on page 38).

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 42).

To create wide, enveloping sound field environments 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 dramatic 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 surround information as long as the program is broadcast in stereo. Thus, movies with surround sound may be decoded via any of the analog surround 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 growing number of made-for-television programs, sports broadcasts, radio dramas and music CDs are also recorded in surround sound. You may view a list of these programs at the Dolby Laboratories Web site at www.dolby.com.

Even when a program is not listed as carrying intentional surround information, you may find that the Dolby Pro Logic II, Dolby Pro Logic IIx, DTS NEO:6 Music or Logic 7 Music or Enhanced modes often deliver enveloping surround presen- tations through the use of the natural surround information present in all stereo recordings.

However, for stereo programs without any surround 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.

Surround modes are selected using either the front panel controls or the remote. To select a new surround mode from the front panel, first press the Surround Mode Group Selector Button 5 until the desired major surround mode group such as Dolby, DTS or Logic 7 is selected. Next, press the Surround Mode Selector Button 9 to choose the specific individual surround mode.

To select a surround mode using the remote control, press the button for the major surround mode group that includes the mode you wish to choose from: Dolby M, DTS Surround N,

DTS Neo:6 , Logic 7 O, Stereo or DSP Surround A. The first press of the button will show the current mode from that group if it is already in use, or the first available mode if you are currently using another mode. To cycle through the available modes in that group press the button again until the desired mode appears in the Lower Display Line ˜ and the on- screen display.

To select from the DSP modes (Hall 1, Hall 2, Theater) press the Surround Mode Selector

Arepeatedly to scroll through the list of available modes.
