ENGLISH33DTS-ES Extended Surround TMDTS-ES Extended Surround is a new multi-channel digital signal format developed by Digital Theater SystemsInc. While offering high compatibility with the conventional DTS Digital Surround format, DTS-ES ExtendedSurround greatly improves the 360-degree surround impression and space expression thanks to furtherexpanded surround signals. This format has been used professionally in movie theaters since 1999.In addition to the 5.1 surround channels (FL, FR, C, SL, SR and LFE), DTS-ES Extended Surround also offers theSB (Surround Back, sometimes also referred to as “surround center”) channel for surround playback with a totalof 6.1 channels. DTS-ES Extended Surround includes two signal formats with different surround signalrecording methods, as described below.2 DTS-ESTM Discrete 6.1DTS-ES Discrete 6.1 is the newest recording format. With it, all 6.1 channels (including the SB channel) arerecorded independently using a digital discrete system. The main feature of this format is that because theSL, SR and SB channels are fully independent, the sound can be designed with total freedom and it ispossible to achieve a sense that the acoustic images are moving about freely among the backgroundsounds surrounding the listener from 360 degrees.Though maximum performance is achieved when sound tracks recorded with this system are played usinga DTS-ES decoder, when played with a conventional DTS decoder the SB channel signals are automaticallydown-mixed to the SL and SR channels, so none of the signal components are lost.2 DTS-ESTM Matrix 6.1With this format, the additional SB channel signals undergo matrix encoding and are input to the SL and SRchannels beforehand. Upon playback they are decoded to the SL, SR and SB channels. The performanceof the encoder used at the time of recording can be fully matched using a high precision digital matrixdecoder developed by DTS, thereby achieving surround sound more faithful to the producer’s sound designaims than with conventional 5.1- or 6.1-channel systems.In addition, the bit stream format is 100% compatible with conventional DTS signals, so the effect of theMatrix 6.1 format can be achieved even with 5.1-channel signal sources. Of course it is also possible toplay DTS-ES Matrix 6.1 encoded sources with a DTS 5.1-channel decoder.When DTS-ES Discrete 6.1 or Matrix 6.1 encoded sources are decoded with a DTS-ES decoder, the formatis automatically detected upon decoding and the optimum playing mode is selected. However, someMatrix 6.1 sources may be detected as having a 5.1-channel format, so the DTS-ES Matrix 6.1 mode mustbe set manually to play these sources.(For instructions on selecting the surround mode, see page 21.)The DTS-ES decoder includes another function, the DTS Neo:6 surround mode for 6.1-channel playback ofdigital PCM and analog signal sources.2 DTS Neo:6 TM surroundThis mode applies conventional 2-channel signals to the high precision digital matrix decoder used for DTS-ES Matrix 6.1 to achieve 6.1-channel surround playback. High precision input signal detection and matrixprocessing enable full band reproduction (frequency response of 20 Hz to 20 kHz or greater) for all 6.1channels, and separation between the different channels is improved to the same level as that of a digitaldiscrete system.DTS Neo:6 surround includes two modes for selecting the optimum decoding for the signal source.• DTS Neo:6 CinemaThis mode is optimum for playing movies. Decoding is performed with emphasis on separationperformance to achieve the same atmosphere with 2-channel sources as with 6.1-channel sources.This mode is effective for playing sources recorded in conventional surround formats as well, becausethe in-phase component is assigned mainly to the center channel (C) and the reversed phase componentto the surround (SL, SR and SB channels).• DTS Neo:6 MusicThis mode is suited mainly for playing music. The front channel (FL and FR) signals bypass the decoderand are played directly so there is no loss of sound quality, and the effect of the surround signals outputfrom the center (C) and surround (SL, SR and SB) channels add a natural sense of expansion to thesound field.If a problem should arise,first check the following.1. Are the connections correct ?2. Have you operated the receiver according to the Operating Instructions ?3. Are the speakers, turntable and other components operating property ?If this unit is not operating properly, check the items listed in the table below. Should the problem persist, theremay be a malfunction.Disconnect the power immediately and contact your store of purchase.Symptom Cause Measures PageDISPLAY not lit and sound notproduced when power switch setto on.• Power cord not plugged in securely. • Check the insertion of the powercord plug.• Turn the power on with theremote control unit after turningthe POWER switch on.516DISPLAY lit but sound notproduced.• Speaker cords not securelyconnected.• Improper position of the audiofunction button.• Volume control set to minimum.• MUTING is on.• Digital signals not input Digital inputselected.• Connect securely.• Set to a suitable position.• Turn volume up to suitable level.• Switch off MUTING.• Input digital signals or select inputjacks to which digital signals arebeing input.917171817DISPLAY not displayed and thepower indicator flashes at a highrate.• Speaker terminals are short-circuited.• Block the ventilation holes of theset.• The unit is operating at continuoushigh power conditions and/orinadequate ventilation.• Switch power off, connect speakersproperly, then switch power backon.• Turn off the set’s power, thenventilate it well to cool it down.Once the set is cooled down, turnthe power back on.• Turn off the set’s power, thenventilate it well to cool it down.Once the set is cooled down, turnthe power back on.8, 95, 85, 8Sound produced only from onechannel.• Incomplete connection of speakercords.• Incomplete connection ofinput/output cords.• Connect securely.• Connect securely.95 ~ 9Positions of instrumentsreversed during stereoplayback.• Reverse connections of left andright speakers or left and rightinput/output cords.• Check left and right connections. 9Humming noise producedwhen record is playing.• Ground wire of turntable notconnected properly.• Incomplete PHONO jackconnection.• TV or radio transmission antennanearby.• Connect securely.• Connect securely.• Contact your store of purchase.55—Howling noise produced whenvolume is high.• Turntable and speaker systems tooclose together.• Floor is unstable and vibrates easily.• Separate as much as possible.• Use cushions to absorb speakervibrations transmitted by floor.
