User manual ROTEL RMD-82

[. . . ] 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. 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. [. . . ] 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 DSP MODES in the processor use digital delay and reverberation effects to simulate progressively larger acoustic environments with DSP 1 being the smallest type of venue (such as a jazz club) and DSP 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. . 2CH/5CH/7CH stereo formats The RMD-82 also provides four modes that disable all surround processing and deliver stereo signals to amplifiers and speakers. The four options are: 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 RMD-82'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. The left channel signal is sent, unchanged, to the front left and surround left speakers. The right channel is sent to the front right and surround right speakers. 7CH Stereo: This mode is the same as 5CH Stereo described above except that it also distributes stereo signals to center back speaker(s) installed in the system. 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 processor what decoding format is required. For example, when Dolby Digital 5. 1 or DTS 5. 1 channel surround is detected, the processor activates the proper decoding. · Downmixed 2-channel playback of Dolby Digital 5. 1 or DTS recordings. · Dolby 3-channel stereo (left/right/center) of 2-channel recordings. · One of four DSP modes for DSP concert hall simulation from 2channel music recordings. Note: In addition to the options that follow, you can press the 2CH button on the front panel or the remote to toggle between 2channel downmix and multichannel playback. · 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 options: 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. 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 will probably be the better 6. 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 PLIIx Mode button on the front panel until the desired center back channel option is selected. Press the SUR+ button on the remote, then use the +/­ buttons to step through six options: DD 2. 0 channel downmix, DD 5. 1 channel, DD Surround EX center back processing, DD with English 33 Pro Logic IIx Music center back processing, DD with Pro Logic IIx Cinema back channel processing, or DD with Rotel XS center back processing. You should typically select Surround EX or discs that are labeled Dolby Digital Surround EX. [. . . ] · Make sure that the IR sensor on the front panel is not blocked. · Make sure the sensor is not receiving strong IR light (sunlight, halogen lighting, etc. ) · Unplug the unit from the AC outlet, wait 30 seconds, and plug it back in to reset. No video from Zones 2, 3 or 4 · Check ZONE SETUP configuration and zone video input setting as assigned and make sure that a Composite source is connected. Also with Blu-ray, but depending on the monitor being used to view the picture, you may also be able to enjoy new video enhancements such as Deep Color or XY video (also called Broad Color Space). Using the HDMI 1. 3 connection, the RMD-82 can pass these signals through from the Blu-ray player to a compatible monitor. [. . . ]
