About the Listening Modes
With its built-in surround-sound decoders and DSP programs, the AV receiver can transform your home listening room into a movie theater or concert hall. If you connect two surround back speakers (i.e., left and right), both will be used for 6.1-channel surround playback.
The AV receiver�s surround indicators show which speakers are active in each listening mode.
Front left Center Front right
Dolby Pro Logic II Music
Use this mode to add 5.1 surround to stereo sources such as music CDs and DVDs.
Dolby Pro Logic IIx
If you�ve connected surround back speakers to the AV receiver, Dolby Pro Logic IIx allows you to enjoy 7.1channel playback from 2-channel or 5.1-channel music or movies. Dolby Pro Logic IIx provides a well de�ned, natural multichannel surround-sound experience, putting the listener in a seamless envelope of sound. The added drama and natural sound enhance the listening experience with CDs, movies, and games. Dolby Pro Logic IIx has three modes of operation: Movie mode for movies, Music mode for listening to music, and Game mode for use with games consoles with 2-channel stereo outputs.
Dolby Digital
Subwoofer Surround left Surround back left/ right Surround right
Direct
The selected input source is output by the front left and right speakers only, with minimal processing for a pure sound.
Pure Audio
With this format you can experience the same superb sound that you get at a movie theater or concert hall. Use this mode with DVDs that bear the Dolby Digital logo.
Dolby Digital EX
As an extension of Direct mode, this mode turns off the display, turns off the power to the video circuitry, and minimizes any other possible noise sources, providing a high �delity sound that�s true to the original. (Since the power to the video circuitry is turned off, no video signals are output while this mode is selected.)
Stereo
With an added surround-back channel, this 6.1 channel format offers a heightened sense of space, for added realism with moving sounds, such as those that rotate 360 degrees or pass overhead. Dolby Digital EX material can also be played on conventional 5.1 channel systems, in which case the surroundback channel audio is split between the surround left and right channels. Use this mode with DVDs that have a 5.1-channel soundtrack and bear the Dolby Digital logo.
DTS
The selected input source is processed as a stereo signal and output by the front left and right speakers and the subwoofer.
Mono or
This digital surround format offers a surround sound experience with exceptional �delity. It uses compressed digital audio data, with six discrete channels (5.1), and the ability to handle large amounts of audio data while remaining faithful to the original. DTS provides very high-quality sound. You�ll need a DTS compatible DVD player in order to enjoy DTS material. Use this mode with DVDs, LDs, or CDs that bear the DTS logo.
DTS 96/24
Use this mode when watching an old movie with a mono soundtrack, or to select multilingual soundtracks recorded in the left and right channels of some movies. It can also be used when playing a DVD or other source with multiplexed audio, such as a karaoke DVD.
T-D (Theater-Dimensional) or
With this mode you can enjoy a virtual 5.1 surround sound even with only two or three speakers. This works by controlling how sounds reach the listener�s left and right ears. Good results may not be possible if there�s too much reverb, so we recommend that you use this mode in an environment with little or no natural reverb.
Dolby Pro Logic II Movie
This mode provides higher audio quality. Use it with CDs, DVDs, and LDs that bear the DTS 96/24 logo.
DTS-ES Discrete
Use this mode with DVDs and videos that bear the Dolby Surround logo or TV programs that feature Dolby Surround. You can also use this mode with stereo movies or TV programs and the AV receiver will create a 5.1 surround mix from the 2-channel stereo.
This is DTS with an added surround back channel for 6.1 surround sound. Use it with program material recorded in DTS 6.1 format. With the additional surround back channel, this format offers 6.1 fully independent digital channels, providing a realistic sense of movement and space. Use it with program material recorded in DTS 6.1, such as CDs, DVDs, or LDs that bear the DTS-ES logo.
