[. . . ] 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 RT-870L 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 RT-870L'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, the bandwidth is too high for today's digital connection. Thus, these discs must be decoded by SACD compatible player, with the output sent to the RPS-1098's MULTI INPUTS. 24 MP3: The RT-870L also features a decoder for the digital MP3 (MPEG1- Audio Layer 3) compression format. MP3 format recordings are available on the Internet and can be played on portable MP3 players or some disc players that can read CD-ROM discs connected to the RT-870L's digital inputs. MPEG Multichannel: The RT-870L can decode MPEG Multichannel digital recordings. Widely used in Europe, this format uses MPEG data compression to record up to 5. 1 channels of discrete digital audio, similar in function to the Dolby Digital and DTS formats. A digital signal coming into the RT-870L will be recognized and properly decoded. However, on a DVD with multiple soundtracks, you must tell the DVD player which one to send to the RT-870L. Press the SUR+ button on the remote, then use the +/­ buttons to step through four options: DD 5. 1 channel, DD 2. 0 channel downmix, DD Surround EX center back processing, or DD with Rotel XS center back processing. On the front panel, press the MODE button while playing a Dolby Digital source. Then, rotate the FUNCTION knob to step through the same options. You should force Surround EX on for non-flagged discs that are labeled Dolby Digital Surround EX. Rotel XS processing of standard 5. 1 channel discs will provide a more diffuse surround effect than the more highly localized Dolby EX decoding and will probably be the best 6. 1 channel option for non-Surround EX discs. · On a 6. 1/7. 1 system with a Dolby Digital Surround EX disc. Press the SUR+ button on the remote, then use the +/­ buttons to step through three options: DD 5. 1 channel, DD 2. 0 channel downmix, or Surround EX center back processing. On the front panel, press the MODE button while playing a Dolby Digital source. Then, rotate the FUNCTION knob to step through the same options. Select the Surround EX option for 6. 1 channel playback. Select the DD 5. 1 option to force Surround EX off for standard 5. 1 channel playback. NOTE: When playing any Dolby Digital source, · To select Cinema, Music, or Emulation option in Pro Logic II mode. [. . . ] · Make sure that MUTING is off and VOLUME is turned up.
