•For private listening, plug the 1/4" stereo phone plug from a pair of stereo headphones into the front-panel

Headphone Jack %. When the headphone’s plug is connected, the word HEADPHONE will scroll once across the Lower Display Line E and all speakers will be silenced. When the headphone plug is removed, the audio feed to the speakers will be restored.

Surround Mode Selection

One of the most important features of the CVR700 is its ability to reproduce a full multichannel sound field from digital sources, analog matrix surround-encoded programs and standard stereo programs.

Selection of a surround mode is based on personal taste, as well as the type of program source material being used. For example, motion pictures or TV programs bearing the logo of one of the major sur- round-encoding processes, such as Dolby Surround or DTS Stereo may be played in either the Dolby Digital, Dolby Pro Logic II Movie, Dolby Pro Logic IIx Movie, DTS Neo:6 Cinema, or Logic 7 Cinema surround modes, depending on the source material.

NOTE: Once a program has been encoded with matrix surround information, it retains the surround information as long as the program is available in stereo. Thus, movies with surround sound may be decoded via any of the analog surround modes such as Dolby Pro Logic II or IIx Movie, Logic 7 Cinema or DTS Neo:6 Cinema, when they are broadcast via con- ventional TV stations, cable, pay-TV and satellite transmission. Also, a number of TV programs, sports broadcasts and radio dramas are recorded in surround sound.

Even when a program is not listed as car- rying intentional surround information, you may find that the Dolby Pro Logic II, Logic 7, DTS Neo:6 and the Hall or Theater modes often deliver enveloping surround presentations through the use of the natural information present in all stereo recordings.

Surround modes may be changed at any time by using either the front panel or remote control. To select a new surround mode from the front panel, press the

Surround Mode Selector *repeatedly until the desired surround mode is selected.

To select a surround mode using the remote, press the button for the surround mode group that includes the mode you wish to choose: Dolby p 14 , DTS Digital o 14 , DTS Neo:6 e 14 , Logic 7 i 14 , Stereo p 14 or DSP Surround g 14 . 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 cur- rently 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 Eand in the front-panel

Surround Mode Indicators G.

The Dolby Digital, Dolby Digital EX, DTS 5.1, DTS-ES Matrix and DTS-ES Discrete modes may only be selected when a digi- tal input is in use. In addition, when a digital source is present, the CVR700 will automatically select and switch to the correct mode, regardless of the mode that has been previously selected. For more information on selecting digital sources, see the Digital Audio Playback section below.

When a DVD-Audio disc is in use, there is no surround processing, as the analog output signal from a DVD-Audio disc is carried straight through to the preamp section.

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

Stereo Mode Select Button m 14

until SURROUND OFF appears in the Lower Display Line E. From the front

panel, press the Surround Mode Selector

*until SURROUND OFF appears in the Lower Display Line E.

Digital Audio Playback

Digital audio is a major advancement over analog surround processing systems. It delivers up to six discrete channels, and each channel reproduces full frequency range (20Hz to 20kHz) and offers dramati- cally improved dynamic range and signifi- cant improvements to signal-to-noise ratios. In addition, digital systems have the capability to deliver an additional channel that is specifically devoted to low-fre- quency information. This is the “.1” chan- nel referred to when you see these sys- tems 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 is a standard part of DVD, available on specially encoded LD discs and satellite broadcasts, and is a part of the high-definition television (HDTV) system.

An optional, external RF demodulator is required to use the CVR700 to listen to the Dolby Digital soundtracks available on laser discs. Connect the RF output of the LD player to the demodulator and then connect the digital output of the demodulator to the Optical or Coaxial Inputs cefhij9)of the CVR700 corresponding to the source (e.g., AUX) you wish to use for your LD player. No demodulator is required for use with DVD players or DTS-encoded laser discs. The CVR700’s internal DVD/CD changer will automatically detect and play any Dolby DVD loaded into it, and no external connections need to be made. However, the CVR700 is not capable of playing a laser disc, and an external LD player must be connected to the CVR700.

DTS

DTS is a digital audio system capable of delivering 5.1 or 6.1 discrete or matrix sound field reproduction. 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.

DTS-encoded soundtracks are available on select DVD and LD discs, as well as on audio-only DTS discs. The CVR700’s internal DVD/CD changer will automati- cally detect and play any DTS-encoded DVD loaded into it, and no external con- nections need to be made. If you are con- necting an external device to the CVR700, be aware that you may use any LD or CD player equipped with a digital output to play DTS-encoded discs with the CVR700. All that is required is to connect the player’s output to either an Optical

or Coaxial Input on the rear panel cefhij or front panel 9).

In order to listen to DVDs encoded with DTS soundtracks, the DVD player must be compatible with the DTS signal, which is indicated by the “DTS Digital Out” logo on the player’s front panel. Some early DVD players were not able to play DTS- encoded DVDs. This does not indicate a problem with the CVR700, as those play-
