Harman Kardon DPR 2005 Owners Manual - Page 33

OPERATION Selecting a Digital Source To utilize either digital mode, you must have properly connected a digital source to the DPR 2005. Connect the digital outputs from DVD players, HDTV receivers, satellite systems or CD players to the Optical or Coaxial Inputs fl‡HJ. 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 their appropriate inputs on the DPR 2005 rear panel (e.g., connect the analog stereo audio output from a DVD to the DVD Inputs ¶ on 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 21, first select the desired input using the remote or front-panel controls, as outlined in this manual. Next, press the Digital Select Button pE and then using the ⁄/¤ Navigation Button o on the remote or the ⁄/¤ Buttons ! on the front panel, choose any of the OPTICAL or COAXIAL inputs, as they appear in the Upper Display Line ^ or on-screen display. When the digital source is playing, the DPR 2005 will automatically detect which type of digital data stream is being decoded and display that information in the Upper Display Line ^. When both a digital and an analog connection are made between a source device and the DPR, the digital input is the default. If the digital stream is not present or is interrupted, the unit will automatically switch over to the analog inputs for the selected source. Digital Bitstream and Surround Mode Indications When a digital source is playing, the DPR senses the type of bitstream data that is present. Using this information, the correct surround mode will automatically 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 DPR 2005 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 DPR 2005 will display a message to indicate the type of bitstream being received. This message will appear shortly after an input or surround mode is changed, and will remain in the Lower Display Line & for about five seconds before that portion of the display returns to the normal surround mode indication. For Dolby Digital and DTS sources, a three-digit indication will appear, showing the number of channels present in the data. An example of this type of display is 3/2/.1. The first number in the display message indicates how many discrete front-channel signals are present. • A "3" tells you that separate front left, center and front right signals are available. This will be displayed for Dolby Digital 5.1 and DTS 5.1 programs. • A "2" tells you that separate front left and right signals are available, but there is no discrete center channel signal. This will be displayed for Dolby Digital bitstreams that have stereo program material. • A "1" tells you that there is only a mono channel available in the Dolby Digital bitstream. The middle number in the display message indicates how many discrete surround channel signals are present. • A "3" tells you that separate, discrete left surround, center surround and right surround signals are present. This is available only on discs with DTS-ES digital audio. • A "2" tells you that separate surround left and right signals are available. This will be displayed for Dolby Digital 5.1 and DTS 5.1 programs. • A "1" tells you that there is only a single, surroundencoded surround channel. This will appear for Dolby Digital bitstreams that have matrix encoding. • A "0" indicates that there is no surround channel information. This will be displayed for two-channel stereo programs. The last number indicates whether there is a discrete low-frequency effects (LFE) channel. This is the ".1" in the common abbreviation of "5.1" sound and it is a special channel that contains only bass frequencies. • A ".1" tells you that an LFE channel is present. This will be displayed for Dolby Digital 5.1 and DTS 5.1 programs, as available. • A "0" indicates that there is no LFE channel information available. However, even when there is no dedicated LFE channel, low-frequency sound will be present at the subwoofer output when the speaker configuration is set to show the presence of a subwoofer. • The information in the right side of the display will tell you if the digital audio data contains a special flag signal that will automatically activate the appropriate 6.1 or 7.1 mode. This will be shown as EX-ON or EX-OFF for Dolby Digital bitstreams and ES-ON or ES-OFF for DTS bitstreams. When Dolby Digital 3/2/.1 or DTS or DTS-ES signals are being played, the DPR will automatically switch to the proper surround mode, and no other processing may be selected. When a Dolby Digital signal with a 3/1/0 or 2/0/0 signal is detected, you may select any of the Dolby surround modes. It is always a good idea to check the channel data to make certain that it matches the audio logo information shown on the back of a DVD package. In some cases, you will see an indication for "2/0/0" even when the disc contains a full 5.1, or 3/2/.1, signal. When this happens, check the audio output settings for your DVD player or the audio menu selections for the specific disc being played to be sure that the player is sending the correct signal to the DPR. An UNLOCK message may appear in the Lower Display Line &. This is your indication that the digital audio data stream has been interrupted or is no longer present. When that occurs, the unit's digital signal processor has no signal to lock onto, and is thus "unlocked." You may see this message when a DVD is first started until the stream is playing and the processor determines which mode to apply; or any time the data stream is stopped or paused, such as when the menus of some discs are displayed or when the player is switching between the different sections of a disc. You may also see the message when a satellite receiver, cable set-top or HDTV tuner is in use if the digital audio is temporarily interrupted when channels are changed or when a cable box switches from a channel with a digital data stream to a channel with analog audio only. The UNLOCK message is normal, and does not indicate any problem with your receiver. Rather, it tells you that the incoming data has simply been paused or is not present for a variety of possible reasons. 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 & will briefly show a message with the letters PCM, in addition 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. Note that the sampling rate displayed is that of the incoming digital signal, and not the upsampled rate that may be applied to PCM sources when Dolby Pro Logic, Pro Logic II or Pro Logic IIx processing is applied, as shown on page 22. During PCM playback you may select any surround mode except one of the Dolby Digital or DTS/DTS-ES modes. However, when a CD with HDCD encoding is being played you must select the Surround Off (stereo) mode to take advantage of the HDCD process. HDCD Playback High Definition Compatible Digital,® or HDCD, discs are recorded using a 20-bit encoding and other proprietary processing for the ultimate in CD listening. When OPERATION 33
