46 46ADVANCED FUNCTIONS“3” is used with DTS-ES bitstreams to represent the presence of thediscrete surround back channel in addition to the side surround left andright channels.The third number is used for the LFE channel:“0” indicates no LFE channel.“.1” indicates that an LFE channel is present.The 6.1-channel signals – Dolby Digital EX and DTS-ES Matrix andDiscrete – each include a flag meant to signal the receiver to decodethe surround back channel.For Dolby Digital EX materials, the incoming bitstream will be displayedas 3/2/.1 EX-ON. For older discs, the display may show EX-OFF, butyou will still be able to select the Dolby Digital EX mode manually bypressing the Dolby button on the remote repeatedly, or using the front-panel controls.For DTS-ES materials, the incoming bitstream will be displayed as3/3/.1 ES-ON.Please refer to Table 8 for more information on which surround modesare available with different bitstreams.When a PCM signal is received, the PCM message, followed by thesampling rate of the signal (32kHz, 44.1kHz, 48kHz or 96kHz), willscroll once across the front-panel display.In addition, the Speaker/Channel Input Indicators will indicate thenumber of channels discretely encoded in the signal by displaying aletter inside that channel’s speaker box. The letters flash when no signalis present, such as when a DVD is paused. See Figure 82.Figure 82 – Speaker/Channel Input IndicatorsEven when only two channels – left and right – are present in the signal,the analog surround modes may be used to decode the signal into theremaining channels.NOTE: Dolby Digital 2.0 signals may also include a DolbySurround flag indicating DS-ON or DS-OFF, depending onwhether the 2-channel bitstream contains only stereo informa-tion, or a downmix of a multichannel program that can bedecoded by the Dolby Pro Logic decoder in the AVR. By default,these signals are played in Dolby Pro Logic IIx Movie mode, butyou may select another Dolby surround mode manually.Surround ModesAs mentioned in the Introduction to Home Theater section, surroundmode selection is dependent upon the format of the incoming audiosignal, as well as personal taste. There is no harm in experimenting withall of the modes available with any given source material. Table 8 offersa brief description of each mode the AVR 247 is capable of using, andalso indicates the types of incoming signals or digital bitstreams themode may be used with. Additional information about the Dolby andDTS modes is available on the companies’ Web sites: www.dolby.comand www.dtsonline.com.When in doubt, check the jacket of your DVD for more information onwhich surround modes are available on the disc. Usually nonessentialsections of the disc, such as trailers, extra materials or the disc menu,are only available in Dolby Digital 2.0 (2-channel) or PCM 2-channelmode. If the main title is playing and the letters in the Speaker/ChannelInput Indicators are not lit for all speaker locations, look for an audiosetup section in the disc’s menu. Also, make sure your DVD player’saudio output is set to the original bitstream rather than just PCM. Checkthe DVD player’s output setting by stopping play of the disc and checkingthe DVD player’s menu system.As indicated in Table 8, different surround modes may only be availablewith certain input signals or bitstream formats. For any incoming signal,only a limited number of surround modes are available. Although there isnever a time when all of the AVR 247’s surround modes are available,there is usually a wide variety of modes available for a given input.There are three methods of manually selecting one of the availablesurround modes:1. From the front panel, press the Surround Mode Button until thedesired mode group (Dolby, DTS, DSP, Stereo, Logic 7) is selected,and the last-used mode from that group will be activated. Then pressthe Surround Select Button repeatedly to scroll through the modesavailable within that group.2. Using the remote, press the button for the desired mode group:Dolby Sur for Dolby modesDTS Sur for DTS Digital modesDTS Neo:6 for the DTS Neo:6 modesLogic 7 for the Logic 7 modesStereo for the Stereo or Surround Off modesSurr for the DSP Surround modes (Hall 1, Hall 2, Theater)Press the mode button repeatedly to scroll through the modesavailable within that group.3. The full-OSD menu system allows access to submenus for each ofthe mode groups through the Surround Setup menu. See Figure 81.Figure 81 (repeated) – Surround Setup Menu ScreenPress the Set Button to access the Surround Setup menu, as shown inFigure 81.
