[. . . ] DVD 48 DV D AUDIO/VIDEO AND SACD TM PLAYER WITH HDMI TM SAFETY INFORMATION home, consult your product dealer or local power company. For products intended to operate from battery power, or other sources, refer to the operating instructions. This product may be equipped with a polarized alternating-current-line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. [. . . ] However, a disc recorded in the 4:3 aspect ratio will appear as a boxed image in the center, with black or gray bars on the left and right side of the screen. If the widescreen option is chosen and a widescreen movie is played on a conventional 4:3 aspect ratio set, the image will be distorted due to vertical compression. · 4:3 Letterbox: If you have a standard, 4:3 aspect ratio video display, choose this setting to see the entire frame of the movie as it is recorded on the disc without any image cutoff at the left and right sides. While this allows widescreen movies to be shown in their entirety, they will occupy a smaller portion of the screen and black "letterbox" bars may appear at the top and bottom of the screen. · 4:3 Pan Scan: This setting is useful only with a few specially encoded DVDs; with all others, the letterbox format fits best when a standard 4:3 aspect ratio video display is in use. For these special DVDs widescreen movies will fill the entire screen. However, you won't see parts of the picture (particularly the right and left edges). Most discs produced in a widescreen format can't be cropped in this fashion, which means the black bars will appear at the top and bottom of the screen (letterbox format). Some widescreen DVDs, particularly anamorphic types, may be shown with original width but spread vertically. With these discs, the letterbox format must be selected. TV Type: This setting allows you to specify whether your video display uses the NTSC (used in North America) or PAL (used in Europe and other parts of the world) video format. The DVD 48 is capable of recognizing and playing DVDs in the PAL format, but only if they are encoded for Region 1 or Region 0 (open region, playable worldwide). The DVD 48 automatically converts the video to the NTSC format for output to your video display. If you have inadvertently changed this setting to PAL and your picture is too distorted for you to view the on-screen menus, you may reset the setting to the default NTSC by following these steps: 29 · CUT-OFF Frequency: This setting selects the frequency below which all signals are sent to the subwoofer. Consult the speaker frequency response specifications that you obtained at the beginning of the Speaker Setup process, and locate the speaker with the lowest low-frequency limit. Set the CUT-OFF Frequency to the setting closest to or just above that low-frequency limit. The available settings are 60Hz, 80Hz, 100Hz and 120Hz. When you have finished configuring your speakers, press the Return Button to return to the SYSTEM SETUP menu (Figure 20). INITIAL SETUP 1. Press the Open/Close Button on the front panel to open the disc drawer. Press the Clear Button on the remote control. Enter the numeric code "1211" on the remote. Press the Audio Button (not Audio Mode). [. . . ] SACD (Super Audio Compact Disc): The SACD format is an improvement upon the original compact disc, and was developed by the same companies that originated the CD. Thanks to its high-density format, the SACD disc is capable of storing more than seven times the amount of data as on a standard CD. Engineers realized that if they utilized a much higher sampling frequency in a single-bit format, but eliminated the downsampling required to fit 74 minutes of audio on a standard CD, they could preserve a much higher quality of audio that more closely approximates the original analog signal. In addition, the playback equipment would no longer need to perform an upsampling interpolation to play back the program. [. . . ]
