AVR
Advanced Functions
Much of the adjusting and configuration your AVR requires is handled automatically, with little intervention required on your part. You can also customize your AVR to suit your system and your tastes. In this section we will describe some of the more advanced adjustments available to you.
Audio Processing and Surround Sound
Audio signals can be encoded in a variety of formats that can affect not only the quality of the sound but the number of speaker channels and the surround mode. You may also manually select a different surround mode, when available.
Analog Audio Signals
Analog audio signals usually consist of two channels – left and right. Your AVR is able to process
Digital Audio Signals
Digital audio signals offer greater flexibility and capacity than analog signals, and allow the encoding of discrete channel information directly into the signal. The result is improved sound quality and startling directionality, since each channel’s information is transmitted discretely.
Surround Modes
When in doubt, check the jacket of your disc for more information on which surround modes are available. Usually, nonessential sections of the disc, such as trailers, extra materials or the disc menu, are available only in Dolby Digital 2.0
Multichannel digital recordings are produced in
NOTE: To use the 6.1- and
Digital formats include Dolby Digital 2.0 (two channels only), Dolby Digital 5.1, Dolby Digital EX (6.1), Dolby Digital Plus (7.1), Dolby TrueHD (7.1),
When the AVR receives a digital signal, it detects the encoding method and the number of channels, which is displayed briefly as three numbers, separated by slashes (e.g., “3/2/.1”).
The first number indicates the number of front channels in the signal: “1” represents a monophonic recording (usually an older program that has been digitally remastered or, more rarely, a modern program for which the director has chosen mono as a special effect). “2” indicates the presence of the left and right channels, but no center channel. “3” indicates that all three front channels (left, right and center) are present.
Advanced Functions
The second number indicates whether any surround channels are present: “0” indicates that no surround information is present. “1” indicates that a matrixed surround signal is present. “2” indicates discrete left and right surround channels. “3” is used with
The third number is used for the LFE channel: “0” indicates no LFE channel. “.1” indicates that an LFE channel is present.
The
Dolby Digital 2.0 signals may include a Dolby Surround flag indicating
When a PCM signal is received, the PCM message and the sampling rate (32kHz, 44.1kHz, 48kHz or 96kHz) will appear.
When only two channels – left and right – are present, the analog surround modes may be used to decode the signal into multiple channels. If you would prefer a different surround format than the native signal’s digital encoding, press the Surround Modes button to display the Surround Modes menu (see Selecting a Surround Mode, on page 32).
The Auto Select option sets the surround mode to the native signal’s digital encoding, e.g., Dolby Digital, DTS, Dolby TrueHD or

Once you have programmed the surround mode for each type of audio, select the line from the Surround Modes menu to override the AVR’s automatic
NOTE: Dolby Pro Logic IIx is available only if you have set up the AVR’s Assigned Amp to Surround Back; Dolby Pro Logic IIz is available only if you have set up the AVR’s Assigned Amp to Front Height. See Manual Speaker Setup, on page 36, for more information.
Please refer to Table A12 in the Appendix for more information on which surround modes are available with different bitstreams.
