User manual ROTEL RT-830L

[. . . ] Read all the instructions before connecting or operating the component. Heed all warnings and safety information in these instructions and on the product itself. You must allow a minimum 10 cm or 4 inches of unobstructed clearance around the unit. Do not place the unit on a bed, sofa, rug, or similar surface that could block the ventilation openings. [. . . ] For example, when Dolby Digital 5. 1 or DTS 5. 1 channel surround is detected, the RT-830L 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 RT-830L 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. the default for all of your video inputs, the RT-830L will automatically decode Dolby Digital 5. 1 and DTS soundtracks when they are played and use Pro Logic II matrix decoding for all other recordings. For stereo inputs such as CD and Tuner, you could select STEREO mode as the default for 2-channel playback or Dolby Pro Logic II music mode if you prefer to hear music sources in surround sound. NOTE: DTS, DTS-ES Matrix 6. 1, DTS-ES Discrete 6. 1, DTS 96/24, Dolby Digital, MP3, MPEG Multichannel, HDCD (96kHz), and PCM 2-channel (96kHz) digital signals are auto-detected and cannot be overridden. However, you can choose to use Dolby Digital Surround EX decoding for any Dolby Digital 5. 1 source material. You can also downmix Dolby Digital 5. 1 or DTS 5. 1 recordings for 2-channel playback. Manually Selecting Surround Modes As described in the previous section, the combination of auto-detection of Dolby Digital and DTS recordings and setting default surround modes for each input during the setup of the RT-830L makes operation of surround modes totally automatic. For many users, this automatic surround mode selection will meet all of their listening needs. For users who prefer a more active role in setting surround modes, buttons on the remote and the front panel provide manual selection of surround mode that are not automatically detected or, in some cases, to override an automatic setting. You should typically select Surround EX or discs that are labeled Dolby Digital Surround EX. For standard 5. 1 channel discs, Dolby Pro Logic IIx Music or Rotel XS processing will provide a more diffused surround effect than the more highly localized Dolby EX decoding and may be the better 7. 1 channel options for non-Surround EX discs. Selecting DD 5. 1 forces the center back channel processing off for conventional 5. 1 channel playback. You can also repeatedly press the DOLBY PLII/3ST button on the front panel until the desired center back channel option is selected. NOTE: When playing any Dolby Digital source, you can select one of three dynamic range control settings. See the Dynamic Range topic in the Other Settings section of this manual. · On a 6. 1/7. 1 system. Press the SUR+ button on the remote, then use the +/­ buttons to step through four optons: DD 2. 0 channel, DD with Pro Logic IIx Cinema matrix surround, DD with Pro Logic IIx Music matrix surround, or Dolby Digital 3 channel stereo. You can also repeatedly press the 2CH button on the front panel or the remote to select the same options. · To select Cinema or Music options in Pro Logic II or Pro Logic IIx modes. Press the SUR+ button twice while in Pro Logic II or Pro Logic IIx modes. Then, use the +/­ buttons to select the Music or Cinema options. NOTE: When playing any Dolby Digital source, you can select one of three dynamic range control settings. See the Dynamic Range topic in the Other Settings section of this manual. · On a 6. 1/7. 1 system with a DTSES disc. [. . . ] · Restore all features and settings to the original FACTORY DEFAULT settings. · Activate the memorized USER DEFAULT settings. To restore the FACTORY DEFAULT settings: Place the highlight on the FACTORY DEFAULT line using the UP/DOWN buttons and use the +/­ buttons to change the setting to YES. Press the ENTER button to proceed with resetting the FACTORY DEFAULT settings. The unit will power off and then on, with the factory settings restored. [. . . ]
