Additional Information852 Types of multi-channel signalsDolby Digital (including Dolby Digital EX), DTS (including DTS-ES), DVD-Audio, and Super Audio CD.Note on the above: MUSE 3.1 and MPEG multi-channel audioare not available to North American consumers – same is true forDolby’s AAC.“Source” here does not refer to the type of signal (format) butthe recorded content. Sources can be divided into two majorcategories.2 Types of sources• Movie audio:Signals created to be played in movie theaters. In generalsound is recorded to be played in movie theaters equippedwith multiple surround speakers, regardless of the format(Dolby Digital, DTS, etc.).• Other types of audio:These signals are designed to recreate a 360° sound field usingthree to five speakers.In this case the speakers should surround the listener from allsides to create a uniform sound field from 360°. Ideally thesurround speakers should function as “point” sound sources inthe same way as the front speakers.These two types of sources thus have different properties, anddifferent speaker settings, particularly for the surround speakers,are required in order to achieve the ideal sound.In this case it is important to achieve the same sense ofexpansion as in a movie theater with the surround channels.To do so, in some cases the number of surround speakers isincreased (to four or eight) or speakers with bipolar or dipolarproperties are used.SL : Surround L channelSR : Surround R channelSB : Surround B (back) channelAdditional InformationOptimum surround sound for differentsourcesThere are currently various types of multi-channel signals (signalsor formats with more than two channels).FL CSW FRFL CSW FRSL SRSBSL SRSBMultiple surround speakersMovie theater sound fieldListening roomsound fieldFL CSW FRSL SRThe AVR-3806’s surround speaker selection function makes itpossible to change the settings according to the combinationof surround speakers being used and the surroundingenvironment in order to achieve the ideal surround sound forall sources. This means that you can connect a pair of bipolaror dipolar surround speakers (mounted on either side of theprime listening position), as well as a separate pair of directradiating (monopolar) speakers placed at the rear corners ofthe listening room.Surround back speakersA 6.1-channel system is a conventional 5.1-channel system towhich the “surround back” (SB) channel has been added. Thismakes it easy to achieve sound positioned directly behind thelistener, something that was previously difficult with sourcesdesigned for conventional multi surround speakers. In addition,the acoustic image extending between the sides and the rear isnarrowed, thus greatly improving the expression of the surroundsignals for sounds moving from the sides to the back and fromthe front to the point directly behind the listening position.FL CSW FRSR chSL chChange of positioning and acoustic imagewith 5.1-channel systemsMovement of acoustic image from SR to SLFL CSW FRSL ch SR chSB chChange of positioning and acoustic imagewith 6.1-channel systemsMovement of acoustic image from SR to SB to SLENGLISHENGLISH
