ADVANCED FUNCTIONS
Much of the AVR 160’s performance is handled automatically, with little intervention required on your part. The AVR 160 is capable of being customized to suit your system and your tastes. In this section, some of the more advanced adjustments available are described.
Audio Processing and Surround Sound
Audio signals output by sources are 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. The AVR 160 offers three options for playback:
1.Analog Bypass Mode: The
a)The analog audio inputs for the source must be selected. If necessary, with the remote in AVR device mode, press the Digital Select Button and use the KL Buttons to select “ANALOG”.
b)The tone controls must be disabled by turning off the Tone setting. With the remote in AVR device mode, press the Tone Button and use the KL Buttons to select “TONE OUT”.
c)The
2.DSP Surround Off Mode: The DSP Surround Off mode digitizes the incoming signal and applies the bass management settings, including speaker configuration, delay times and output levels. Select this mode when your front speakers are small,
3.Analog Surround Modes: The AVR 160 is able to process
Digital Audio Signals
Digital audio signals offer greater capacity, which allows the encoding of center and surround channel information directly into the signal. The result is improved sound quality and startling directionality, since each channel is reproduced discretely.
Even when only two channels are encoded, the digital signal allows for a higher sampling rate that delivers greater detail.
Surround Modes
Surround mode selection is dependent upon the format of the incoming audio signal, as well as personal taste. Table A9 offers a brief description of each mode and indicates the types of incoming signals or digital bitstreams the mode may be used with. Additional information about the Dolby and DTS modes is available on the companies’Web sites: www.dolby.com and www. dtsonline.com.
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 only available in Dolby Digital
2.0
For any incoming signal, only a limited number of surround modes are available. Although there is never a time when all of the AVR 160’s surround modes are available, there is usually a wide variety of modes available for a given input.
Multichannel digital recordings are found in the
the
NOTE: To use the 6.1- and
The 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 a digital signal is received, the AVR 160 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 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.
