ers cannot pass through the DTS signal. If you’re in doubt as to the capability of your DVD player to handle DTS discs, consult the player’s owner’s manual.

NOTE: Many DVD players have a default setting that does not pass through the DTS data, even though the machine is capable of doing so. If your external DVD player has the “DTS Digital Out” logo but does not trigger DTS playback in the CVR700, change the player’s settings in the “Audio” or “Bitstream” configuration menu so that DTS playback is enabled. The method for doing this will vary with each player. In some cases, the proper menu choice will be “Original,” while in others it will be “DTS.” Consult the owner’s manual for your player to find the specific information to find the proper setting.

Selecting a Digital Source

To use either digital mode, you must have properly connected a digital source to the CVR700. Connect the digital outputs from external DVD players, HDTV receivers, satellite systems or CD players to the Optical or Coaxial Inputs cefh ij9). In order to provide a backup signal and a source for analog stereo recording, the analog outputs provided on digital source equipment should also be connected to the corresponding inputs on the CVR700 rear panel (e.g., connect the analog stereo audio output from a digital recorder to the Digital Recorder Inputs

ªon the rear panel when you connect the source’s digital outputs).

If you have not already configured an input for a digital source using the on- screen menus as shown on page 46, first select the desired input using the remote or front-panel controls, as outlined in this manual. Next, press the Audio Input Button k 38 and then using the

⁄/¤ Navigation Control q 4 ,

choose the OPTICAL, COAXIAL or ANALOG input you wish to assign to that source, as it appears in the Upper Display Line H. When the digital source is playing, the CVR700 will auto- matically detect which type of digital data stream is being decoded and display that information in the Upper Display Line H. However, the CVR700 will not automatically detect which digital or ana- log audio connection you have made.

Digital Bitstream and Surround Mode Indicators

When a digital source is playing, the CVR700 senses the type of bitstream

data that is present. Using this informa- tion, the correct surround mode will auto- matically be selected. For example, DTS bitstreams will cause the unit to switch to DTS decoding, and Dolby Digital bitstreams will enable Dolby Digital decoding.

When the unit senses PCM data from CDs or LDs, you may select any of the standard surround modes, such as Dolby Pro Logic II or Logic 7. Since the range of available surround modes is dependent on the type of digital data that is present, the CVR700 shows you what type of signal is present. This will help you to understand the choice of modes.

When a digital source is first detected, the CVR700 will indicate the type of bit- stream being received by switching to the appropriate surround mode, depending on the bitstream and how you have config- ured your system. The Speaker/Channel Input Indicators Fwill light to indi- cate which channels are contained in the digital bitstream. For example, for a Dolby Digital EX bitstream, the L, C, R, SL, SR, SBL, SBR and LFE indicators will light with a line between the SBL and SBR boxes to indicate that those two channels are in mono. This is the only indication of the number of channels present in the signal. The Surround Mode Indicator Gthat identifies the bitstream will also light. The Lower Display Line Ewill indicate the sur- round mode you have assigned to that source using the AUDIO MODE sub- menu system or the remote.

When Dolby Digital 5.1 or DTS or DTS-ES signals are being played, the CVR700 will automatically switch to the proper sur- round mode, and no other processing may be selected. When a Dolby Digital signal with 4.0 or 2.0 channels is detected, you may select any Dolby surround mode.

When the digital audio data stream has been interrupted or is no longer present, such as when a DVD disc is paused or stopped, the Speaker/Channel Input Indicators Fwill flash to indicate that no signal is present. This is normal and does not indicate any problem with your system.

PCM Playback

PCM is the abbreviation for Pulse Code Modulation, which is the type of digital signal used for standard CD playback, and other non-Dolby Digital and non-DTS digital sources such as Mini-Disc. When a PCM signal is detected, the Lower Display Line Ewill briefly show a

message with the letters PCM, in addi- tion to a readout of the sampling frequency of the digital signal.

In most cases, this will be PCM 44.1kHz or PCM 48kHz, though in the case of specially mastered, high- resolution audio discs, you will see a PCM 96kHz indication.

During PCM playback, you may select any surround mode except one of the Dolby Digital or DTS/DTS-ES modes.

Speaker/Channel Indicators

In addition to the bitstream indicators, the CVR700 features channel-input indi- cators that show how many channels of digital information are being received and/or whether the digital signal is inter- rupted (see Figure 41).

These indicators are the L/C/R/LFE/ SL/SR/SBL/SBR letters that are inside the center boxes of the Speaker/ Channel Input Indicators Fon the front panel. When a standard analog sig- nal is in use, only the “L” and “R” indica- tors will light, as analog signals have only left and right channels.

Digital signals may have two, five, six or seven channels, depending on the pro- gram material, its method of transmission and the way in which it was encoded. When a digital signal is playing, the let- ters in these indicators will light in response to the signal being received. It is important to note that although Dolby Digital, for example, is referred to as a “5.1” system, not all Dolby Digital DVDs or programs are encoded for 5.1. Thus, it is sometimes normal for a DVD with a Dolby Digital soundtrack to trigger only the “L” and “R” indicators.

NOTE: Many DVD discs are recorded with both “5.1” and “2.0”, and Dolby Digital and DTS versions of the same soundtrack. When playing a DVD, always be certain to check the type of material on the disc. Most discs show this infor- mation using icons on the back of the disc jacket. When a disc offers multiple soundtrack choices, you may have to make some adjustments (usually with the “Audio Select” button or in a menu screen on the disc) to access the full 5.1
