User manual ROTEL RT-950BX

[. . . ] If the unit is exposed to moisture, or a foreign object gets into the enclosure, immediately disconnect the power cord from the wall. Take the unit to a qualified service person for inspection and necessary repairs. Read all the instructions before connecting or operating the component. Keep this manual so you can refer to these safety instructions. [. . . ] MP3: The RT-950BX 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-950BX's digital inputs. MPEG Multichannel: The RT-950BX 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. Other Digital Formats Several other digital formats are not surround sound formats at all, but rather systems for digital 2-channel recordings. PCM 2-channel: This is an uncompressed 2-channel digital signal such as that used for standard CD recordings and some DVD recordings, particularly of older films. HDCD®: This system uses higher bit rates and a variety of enhancements to improve the sonic performance compared to standard audio CDs. These discs, labeled HDCD, can be played on standard CD players. However, when the digital signal is decoded using an HDCD decoder like that in the RT-950BX, they will provide exceptional musical reproduction. DTS Music 5. 1 Discs: These discs are a variation of audio CDs that include a DTS 5. 1 channel recording. The RT-950BX decodes these discs just like a DTS movie soundtrack when played on a CD player or DVD player with a digital output connection. DVD-A music discs: Taking advantage of the increased storage capacity of the DVD disc, new high bit rate multichannel audio recordings are available on DVD-A discs. The right channel is sent 27 English A digital signal coming into the RT-950BX 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-950BX. For example, you may need to use the DVD's menu system to select the Dolby Digital 5. 1 or DTS 5. 1 soundtrack rather than the default Dolby Digital 2. 0 Dolby Surround soundtrack. NOTE: · Dolby 3-channel stereo (left/right/center) of 2-channel recordings. · 5-channel or 7-channel stereo from 2-channel recordings. · One of four MUSIC modes for DSP concert hall simulation from 2-channel recordings. · Dolby Pro Logic II cinema or music mode matrix decoding of 2-channel recordings. · DTS Neo:6 cinema or music mode matrix decoding of 2-channel recordings. · Dolby Digital Surround EX decoding of Dolby Digital 5. 1 channel recordings or Dolby Digital Surround EX discs that do not trigger automatic decoding. · On a 5. 1 system. Press the SUR+ button on the remote, then press the +/­ buttons to change between DD 5. 1 channel or DD 2. 0 channel downmix playback. Press the SUR+ button on the remote, then use the +/­ buttons to step through five optons: DD 2. 0 channel downmix, DD 5. 1 channel, DD Surround EX center back processing, DD with Pro Logic IIx Music center back processing or DD with Rotel XS center back processing. You should typically select Surround EX or discs that are labeled Dolby Digital Surround EX. [. . . ] · The unit uses relay switching to preserve maximum sound quality. The mechanical clicking of the relays is normal. · During switching, it may take a split second for digital signals to be recognized and properly decoded. Rapid repeated switching between inputs or settings can result in clicks or pops from the speakers as the unit attempts to lock on to the rapidly changing signals. [. . . ]
