Operation

•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 Surround Mode Group Selector 5 to cycle through the three Dolby Headphone modes to select the one that you prefer.

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.

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 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.

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 following 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.

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 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 42).

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 47).

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 dramatic improvement in comparison to the Dolby Pro Logic (I) mode of former times.

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 TC 30 remote, first press the Devices Button 4, followed by the Screen Button 6 at the top of the row of buttons on the left side of the TC 30, to the left of the A/V receiver image on the LCD screen. After the list of options displayed on the LCD Screen 7 changes, press the Screen Button 6 to the right of SURR MENU. The options list will change again, this time showing the major display category modes. The first press of a 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 ˜, the on-screen display and the front- panel Surround Mode Indicators Ò.

To listen to a program in traditional two-channel stereo, using the front left and front right speakers only (plus the subwoofers, if installed and configured), first follow the instructions shown above so that the AVR: SURROUND MENU page of the TC 30 remote is on the LCD Screen 7, and then press the Screen Button

6to the right of the Stereo option until SURROUND OFF appears in the Lower Display Line ˜. From the front panel, press the Surround Mode Group Selector 5 until the Stereo modes appear in the on-screen display and Lower Display Line ˜. Next, press the Surround Mode Selector Button 9 until SURROUND OFF appears in the on-screen display and Lower Display Line ˜.

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 repro- duces 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 infor- mation. 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.
