User manual ROTEL RT-950BX

[. . . ] 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 of 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. [. . . ] 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-950BX'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 RT-950BX 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 RT-950BX 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 RT-950BX what decoding format is required. For example, when Dolby Digital 5. 1 or DTS 5. 1 channel surround is detected, the RT-950BX 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. For standard 5. 1 channel discs, Dolby Pro Logic IIx Music or Rotel XS processing will provide a more diffuse 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, Additionally, you can configure a default surround mode for each input using the INPUT SETUP menu (see the Setup section of this manual). Combined with the auto-detection of Dolby Digital 5. 1 and DTS, this default surround setting makes operation of the RT-950BX surround modes totally automatic. For example, if you set Dolby Pro Logic II movie mode as the default for all of your video inputs, the RT-950BX 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. 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. NOTE: 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-950BX 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. Manual settings available from the front panel and/or the remote might be used when you want to play: · Standard 2-channel stereo (left/right speakers only) with no surround processing. [. . . ] 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. To return to the MAIN To activate memorized USER DEFAULT settings: After you have stored a USER DEFAULT configuration file, you can activate those settings at any time by placing the highlight on the USER DEFAULT line using the UP/ DOWN buttons.
