34 OPERATIONOperationIt is always a good idea to check the readout forthe channel data to make certain that it matchesthe audio logo information shown on the back ofa DVD package. In some cases you will see indi-cation for “2/0/0” even when the disc contains afull 5.1, or 3/2/.1 signal. When this happens,check the audio output settings for your DVDplayer or the audio menu selections for the spe-cific disc being played to make certain that theplayer is sending the correct signal to the AVR.PCM Playback IndicationsPCM is the abbreviation for Pulse CodeModulation, which is the type of digital signalused for standard CD playback, and other non-Dolby Digital and non-DTS digital sources suchas Mini-Disc. When a PCM signal is detected, theMain Information Display Ò will brieflyshow a message with the letters PCM, in addi-tion to a readout of the sampling frequency ofthe digital signal.Connections may be made to either the rear-panel Optical or Coaxial Inputs or thefront-panel Digital Inputs *Ó.To listen to a PCM digital source, first select theinput for the desired source (e.g., CD). Next pressthe Digital Select Button ÛG and thenuse the ⁄/¤ Buttons D on the remote, orthe ‹/› Selector Buttons 7 on the frontpanel, until the desired choice appears in theUpper Display Line Ò.During PCM playback, you may select anySurround mode except Dolby Digital or DTS, asshown in the table below. Note that for conven-ience, we have included the modes available foranalog sources (including the tuner) in the charton the bottom of this page.In most cases this will be 4 8 KHZ, though inthe case of specially mastered, high-resolutionaudio discs you will see a 9 6 KHZ indication.The PCM 4 8 KHZ indication will also appearwhen modes or inputs are changed for analogsources. In those cases the system is telling youthe sampling frequency used internally at theoutput of the analog-to-digital converters thatchange the incoming signal from a VCR, tapedeck, the tuner, or other ana-log source to digi-tal.Speaker/Channel IndicatorsIn addition to the Bitstream Indicators, theAVR features a set of unique channel-inputindicators that tell you how many channels ofdigital information are being received and/orwhether the digital signal is interrupted.(See Figure).These indicators are the L/C/R/LFE/SL/SR lettersthat are inside the center boxes of theSpeaker/Channel Input Indicators $ in thefront panel Main Information Display Ò.When a standard analog stereo or matrixsurround signal is in use, only the “L” and “R”indicators will light, as analog signals have onlyleft and right channels.Digital signals, however, may have one, two, fiveseparate channels, depending on the programmaterial, the method of transmission and theway in which it was encoded. When a digitalsignal is playing, the letters in these indicatorswill light in response to the specific signal beingreceived. It is important to note that althoughDolby Digital, for example, is referred to as a“5.1” system, not all Dolby Digital DVDs or audiotracks selected on DVD or other Dolby Digitalprograms are encoded for 5.1.Thus, it is sometimes normal for a DVD with aDolby Digital soundtrack to trigger only the “L”and “R” indicators.Incoming Signal Available Surround ModesAnalog (2-channel), Tuner, PCM 44.1kHz or 48kHz Dolby Pro Logic II (Movie, Music or Game), Dolby Pro Logic, Dolby 3 Stereo, Dolby Virtual SpeakerReference (2 or 3 Speaker), Dolby Virtual Speaker Wide (2, 3, 4 or 5 Speaker), DTS Neo:6 (3-channelCinema, 5-channel Cinema or Music), Logic 7 (5-channel Cinema, Music or Enhance), Hall 1(5-channel), Hall 2 (5-channel), Theater (5-channel), Surround Off**, 5-Channel Stereo,DSP Surround OffPCM 96kHz Dolby Pro Logic II (Movie or Music), Dolby Pro Logic, Logic 7 (5-channel Cinema, Music or Enhance),DSP Surround Off** The Surround Off mode is only available for ananlog sources or the tuner, and requires that the tone controls be removed from the circuitry for “flat” response. Otherwise, the DSP Surround Offmode may be selected when a two-channel presentation is desired.For incoming DTS signals, the following modes are available:Incoming Bitstream Available Surround ModesDTS 1/0/.0, 1/0/.1, 2/0/.0, 2/0/.1, 3/0/.0, 3/0/.1, 3/1/.0 or 3/1/.1 DTS, DTS StereoDTS 2/2/.0, 2/2/.1, 3/2/.0 or 3/2/.1 DTS, DTS StereoDTS 96/24 DTS 96/24, DTS StereoDTS-ES Matrix DTS, DTS StereoDTS-ES Discrete DTS, DTS Stereo30935_AVR145_ENG 01/12/06 9:53 Side 34
