3 2001 MODEL SPECIAL FEATURES A, B, C, D Features for Enhanced Theater Experience Our A, B, C, D functions stand for Advanced Surround (V.S.S.), Bass Plus, Cinema Mode, and Dialog Enhancer - four essential features to enhancing the theater experience. For easy control of image and audio, these functions are grouped in a single location on the front panel of most of our DVD players. The One Touch Memory function on the DVD-RV31K/RV31S/RV41/RP56 even lets you store your function settings for instant recall at the push of a button. (A, B, C, D available on the DVD-RV31K, DVD-RV31S, DVD-RP56, and DVD-CV51. Bass Plus function not available on the DVD-RV41 and DVD-RV45K) · Advanced Surround (V.S.S.) Advanced V.S.S. lets you enjoy the thrilling sound of Dolby Digital® 5.1 channel discs without an elaborate home theater system. With Advanced V.S.S, a surround sound effect is simulated using only the front two speakers*. *This effect also works with Dolby Digital 2-channel discs. "Dolby," "Dolby Pro Logic" and "Dolby Digital" are trademarks of Dolby Laboratories Licensing Corporation. · Bass Plus By connecting an optional subwoofer to your DVD player, you can enjoy enhanced bass sound. When watching a Dolby Digital 5.1-channel disc, the bass tones of the "0.1" channel and the low frequency of other channels are sent to the subwoofer output. This results in clear bass tones for a powerful and realistic ambiance. · Cinema Mode Cinema mode combines brightness control with picture noise canceling to provide better picture quality in certain viewing conditions. It lessens glare, giving you colors that are more cinema-like and picture resolution that is gentler to the eyes. Cinema mode also improves the visibility of details in dark scenes by automatically adjusting picture contrast, and helps to suppress color smearing, as well. · Dialogue Enhancer Most of the movie dialogue recorded in surround sound formats (either Dolby Digital®, DTS®* or Dolby Pro Logic®) is heard through the center channel speaker. At times, dialogue can be overwhelmed by particularly loud sounds emanating from the other speakers in your surround sound system. The dialogue enhancer increases the center channel volume (relative to other channels), making movie dialogue easier to hear and understand. * "DTS" and "DTS Digital Surround" are trademarks of Digital Theater Systems, Inc. Disc Stabilizer Conventional DVD players have a "servo," which helps them to properly play warped discs. Although this feature is generally effective, severely warped discs can be unplayable using this feature alone. Our newly developed Disc Stabilizer applies corrective pressure at the outer edge of DVD discs to minimize overall warpage for improved disc playability. The stabilizer touches the DVD disc only at the disc's innermost and outermost non-signal peripheries, using non-woven material to prevent damaging the surface. (Not available on the DVD-RV45K) CD-R/RW/MP3 Playback Capability For added home entertainment value, most of our DVD-Video home players are equipped to play back your CD-R/RW* and MP3** recordings. (Not available on the DVD-RV45K) Note: For CD-R/RW playback on these models the discs must be one session and the session must be closed. * For CD-DA format audio CD-R and CD-RW discs. May not be able to play some CD-R or CD-RW discs due to the condition of the recording. ** For contents recorded on CD-R/RW media from CDs for your personal use. Playability may vary depending on contents and discs.
