ENGLISH Getting Started Connections Playback Remote Control Troubleshooting SpecificationsMulti-ZoneSettings InformationOther InformationThe AVR-1910 is equipped with a digital signal processing circuit that lets you play program sources in the surround mode to achieve the same sense of presence as in a movie theater.Dolby DigitalDolby Digital is a multichannel digital signal format developed by DolbyLaboratories.A total of 5.1-channels are played: 3 front channels (“FL” , “FR” and“C”), 2 surround channels (“SL” and “SR”) and the “LFE” channel forlow frequencies.Because of this, there is no crosstalk between channels and a realisticsound field with a “three-dimensional” feeling (sense of distance,movement and positioning) is achieved.A real, overpowering sense of presence is achieved when playingmovie sources in AV rooms as well.Dolby Digital PlusDolby Digital Plus is an improved Dolby Digital signal format that iscompatible with up to 7.1-channels of discrete digital sound and alsoimproves sound quality thanks to extra data bit rate performance. Itis upwardly compatible with conventional Dolby Digital, so it offersgreater flexibility in response to the source signal and the conditionsof the playback equipment.Dolby TrueHDDolby TrueHD is a high definition audio technology developed by DolbyLaboratories, using lossless coding technology to faithfully reproducethe sound of the studio master.This format is compatible with a maximum sampling frequency of 96kHz and up to 7.1-channels, so it is used for applications particularlyprioritizing sound quality.Dolby Pro Logic gxDolby Pro Logic gx is a further improved version of the Dolby Pro Logicg matrix decoding technology.Audio signals recorded in 2-channels are decoded to achieve a naturalsound with up to 7.1-channels.There are 3 modes: “Music” suited for playing music, “Cinema”suited for playing movies, and “Game” which is optimized for playinggames.Dolby Pro Logic gDolby Pro Logic g is a matrix decoding technology developed by DolbyLaboratories.Regular music such as that on CDs is encoded into 5-channels toachieve an excellent surround effect.The surround channel signals are converted into stereo and full bandsignals (with a frequency response of 20 Hz to 20 kHz or greater)to create a “three-dimensional” sound image offering a rich sense ofpresence for all stereo sources. Manufactured under license from Dolby Laboratories.“Dolby”, “Pro Logic” and the double-D symbol are trademarks ofDolby Laboratories.Dolby Digital EXDolby Digital EX is a 6.1-channel surround format proposed by DolbyLaboratories that allows users to enjoy in their homes the “DOLBYDIGITAL SURROUND EX” audio format jointly developed by DolbyLaboratories and Lucas Films.The 6.1 channels of sound, including surround back channels, provideimproved sound positioning and expression of space.SurroundDolby SurroundDolby Pro Logic gzDolby Pro Logic gz introduces a new dimension to Home Entertainmentthrough the addition of a pair of front height channels. Compatible withstereo, 5.1 and 7.1 content, Dolby Pro Logic gz provides enhancedspaciousness, depth and dimension to movies, concert video andvideogame playback while maintaining the full integrity of the sourcemix.Dolby Pro Logic gz identifies and decodes spatial cues that occurnaturally in all content, directing this information to the front heightchannels, complementing the performance of left and right surroundsound speakers. Content that is encoded with Dolby Pro Logicgz height channel information can be even more revealing, withperceptually discrete height channel information bringing an excitingnew dimension to home entertainment.Dolby Pro Logic gz, with frontheight channels is also an ideal alternative for households that cannotsupport the placement of back surround speakers of a typical 7.1channel system but may have bookshelf space available to support theaddition of height speakers.DTS SurroundDTS Digital SurroundDTS Digital Surround is the standard digital surround format of DTS,Inc., compatible with a sampling frequency of 44.1 or 48 kHz and upto 5.1-channels of digital discrete surround sound.DTS-ES™ Discrete 6.1DTS-ES™ Discrete 6.1 is a 6.1-channel discrete digital audio formatadding a surround back (SB) channel to the DTS digital surround sound.Decoding of conventional 5.1-channel audio signals is also possibleaccording to the decoder.DTS-ES™ Matrix 6.1DTS-ES™ Matrix 6.1 is a 6.1-channel discrete digital audio formatinserting a surround back (SB) channel to the DTS digital surroundsound through matrix encoding. Decoding of conventional 5.1-channelaudio signals is also possible according to the decoder.DTS-HD High Resolution AudioDTS-HD High Resolution Audio is an improved version of theconventional DTS, DTS-ES and DTS 96/24 signals formats, compatiblewith sampling frequencies of 96 or 48 kHz and up to 7.1-channelsof discrete digital sound. High data bit rate performance provideshigh quality sound. This format is fully compatible with conventionalproducts, including conventional DTS digital surround 5.1-channeldata.DTS-HD Master AudioDTS-HD Master Audio is DTS, Inc’s lossless audio format compatiblewith up to 96 kHz/7.1-channels. The lossless audio coding technologyfaithfully reproduces the sound of the studio master. It is fullycompatible with conventional products, including conventional DTSdigital surround 5.1-channel data.DTS NEO:6™ SurroundDTS NEO:6™ is a matrix decoding technology for achieving 6.1-channel surround playback with 2-channel sources. It includes “DTSNEO:6 Cinema” suited for playing movies and “DTS NEO:6 Music”uited for playing music.
