Operation
sound being recorded from left rear side will be heard from that side only.
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.
To create wide, enveloping sound field environments and defined pans and flyovers with all analog stereo recordings select the Dolby Pro Logic II Music 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 sur- round modes such as Dolby Pro Logic II or Logic 7, when they are broadcast via conventional TV stations, cable, pay TV and satellite transmission. In addition, a growing number of made-for-televi- sion 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 3 Stereo or Logic 7 modes often deliver enveloping surround presentations 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 5CH 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 surround mode from the front panel, press the
Surround Mode Group Selector Button 6 to scroll through the list of available surround groups (for example, any Dolby mode or Logic 7 mode). Next press the Surround Mode Selector Button C to choose the specific mode within the desired group (for example, within the Dolby mode group the options are Dolby Pro Logic, Dolby Pro Logic II Music, Dolby Pro Logic II Movies and Dolby 3 Stereo). To select a surround mode using the remote, any of the surround mode selector buttons IJK PQ until the desired mode appears. As you press the buttons, the Surround mode name will appear in the Main Information Display F. As the surround mode changes, a blue LED will light next to the current mode in the Surround Mode Indicators list D on the front panel. Regard that any time a surround mode is changed it remains associated with the input just selected until another choice is made.
NOTE: The name of each Surround Mode will scroll through the Main Information Display
Fwhile the modes are being selected. To avoid exiting from the surround mode selection process, be certain to push the K/L buttons
while a mode name is still visible.
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.
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), follow the instructions shown above for using the remote until SURR OFF appears in the Main Information Display F.
Digital Audio Playback
Digital audio is a major advancement over older analog matrix surround systems. It delivers five discrete channels: left front, center, right front, left surround and right surround. 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 descibed as “5.1”. 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 satellite broadcasts and is a part of the new high-definition television (HDTV) system.
DTS
DTS is another digital audio system that is capable of delivering 5.1 audio. Although both DTS and Dolby Digital are digital, they use different methods of encoding the signals, and thus they require different decoding circuits to convert the digital signals back to analog.
PCM Audio Playback
PCM (Pulse Code Modulation) is the non- compressed digital audio system used for com- pact discs, and some special PCM encoded DVDs. The digital circuits in the AVR are capable of high quality digital-to-analog decoding, and they may be connected directly to the digital audio output of your CD/DVD player.
Connections may be made to the Optical or
Coaxial inputs on the rear panel or front panel 4G.
To listen to a PCM digital source, first select the input for the desired source (e.g., CD) to feed its video signal (if any) to the TV monitor and to provide its analog audio signal for recording.

When a PCM source is playing, a brief message PCM will appear in the Main Information Display F. During PCM playback you may select any surround mode except Dolby Digital or DTS.
