Important Safety Instructions WARNING: There are no user serviceable parts inside. Refer all servicing to qualified service personnel. WARNING: To reduce the risk of fire or electric shock, do not expose the unit to moisture or water. Do not allow foreign objects to get into the enclosure. [. . . ] DVD-A discs may include multiple versions of the recording including standard PCM stereo, Dolby Digital 5. 1, DTS 5. 1, and 96kHz/24 bit (or higher) multichannel recordings using MLP compression. Several of these formats (standard PCM, Dolby Digital, and DTS 5. 1 can be decoded by the RSP-1068 when the DVD player is connected with a digital cable. However, the existing optical and coax digital connection standard does not provide sufficient bandwidth for multichannel high sampling rate MLP recordings. Therefore, DVD-A discs with these high-resolution audio soundtracks must be decoded by a the DVD player and the resulting analog signals sent to the RSP-1068's MULTI INPUT. SACD®: This is a proprietary high-resolution audio standard for use on SACD compatible disc players. As with high-resolution DVD-A discs, DSP Music Modes Unlike all of the formats mentioned above, the RSP-1068 offers four surround modes that are not part of a specific recording/playback system. These modes (MUSIC 1­4) use digital signal processing that adds special acoustic effects to any signal. DSP processing can be used with Dolby Surround recordings, Dolby Digital recordings, CDs, radio broadcasts, or any other source material; however, typically DSP settings would be used with source material for which there is no specific surround decoder. The four MUSIC MODES in the RSP-1068 use digital delay and reverberation effects to simulate progressively larger acoustic environments with MUSIC 1 being the smallest type of venue (such as a jazz club) and MUSIC 4 being a large venue (such as a stadium). Typically used to add ambience and a sense of space when listening to music sources or other sources that lack surround sound encoding. Automatic Surround Modes Decoding of digital sources connected to the digital inputs is generally automatic, with detection triggered by a "flag" embedded in the digital recording telling the RSP-1068 what decoding format is required. For example, when Dolby Digital 5. 1 or DTS 5. 1 channel surround is detected, the RSP-1068 activates the proper decoding. The unit will also detect DTS-ES Matrix 6. 1 or DTS-ES Discrete 6. 1 discs and activate DTS-ES® Extended Surround decoding. Dolby Digital Surround EX recordings also trigger automatic decoding (although not all Surround EX DVDs have the necessary flag and may require manually activating Surround EX decoding). Likewise, a digital input from an HDCD® encoded compact disc, a standard CD, a DTS 96/24 disc, or MP3 player will be auto-detected and properly decoded to 2CH stereo operation. Dolby Pro Logic IIx or Rotel XS processing can be configured to be automatically active in all 6. 1 or 7. 1 channel systems configured with center back speaker(s) and will ensure proper extended surround decoding of all multichannel digital signals, even those that might not otherwise trigger the proper extended surround mode. In many cases, the RSP-1068 will also recognize a digital signal with Dolby Surround encoding (such as the default soundtrack on many DVDs) and activate Dolby® Pro Logic II® decoding. 2Ch/5Ch/7Ch Stereo Formats The RSP-1068 also provides four modes that disable all surround processing and deliver stereo signals to amplifiers and speakers. There are three options: 2CH Stereo: Turns off the center channel and all surround channels in the system and delivers a conventional 2-channel signal to the front speakers. If the system is configured to route bass signals from the front speakers to the subwoofer, this capability remains in effect. Analog Bypass: For 2-channel analog inputs, there is a special stereo mode that bypasses ALL of the RSP-1068's digital processing. The two front speakers receive pure analog stereo full-range signals with no subwoofer crossover, no delay, no level adjustments, and no contour adjustment. 5CH Stereo: Distributes a stereo signal to 5. 1 channel systems. The left channel signal is sent, unchanged, to the front left and surround left speakers.
