Pacific Digital AVR 635 Surround Mode Selection, Digital Audio Playback, Dolby Digital, Operation

Operation

•To set the output of the AVR so that the output is “flat,” with the tone and balance controls de- activated, 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 but- ton 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 dis- play and the Lower Display Line ˜. Next, use the ⁄/¤ Navigation Button Eon 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 sec- onds 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 connect- ed, 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 head- phone output is in the Bypass mode, and to con- firm 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 listening. Press the Dolby Mode Select Button Mor 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 materi- al 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 sur- round 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 33).

36OPERATION

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 36).

To create wide, enveloping sound field environ- ments and defined pans and flyovers with all ana- log 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 con- ventional 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 presenta- tions through the use of the natural surround infor- mation 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

5until 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 con- trol, 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 avail- able modes.

Note that the Dolby Digital or DTS modes 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 previously selected. For more information on selecting digital sources, see the fol- lowing section of this manual.

When the 6-Channel/8-Channel direct inputs are in use there is no surround processing, as these inputs take the analog output signals from an optional, external DVD-Audio or SACD player, or another source device and carry them straight through to the volume control.

To listen to a program in traditional two-channel stereo, using the front left and front right speakers only (plus the subwoofer, if installed and configured), press the Stereo Button 5

until SURR OFF appears in the Main Information Display ˜.

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 surround 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 improvements to signal-to-noise ratios. In addition, digital systems have the capability to deliver an additional channel that is specifically devoted to low-frequency information. This is the “.1” channel referred to when you see these systems described as “5.1,” “6.1” or “7.1”. The bass channel is separate from the other channels, but since it is intentionally bandwidth-limited, sound designers have given it that unique designation.

Dolby Digital

Dolby Digital (originally known as AC-3®) is a standard part of DVD, and is available on specially encoded LD discs and satellite broadcasts and it is a part of the new high-definition television (HDTV) system.

Note that an optional, external RF demodulator is required to use the AVR to listen to the Dolby
