3 Set the operation selector switch to RCV, then press AUTO/DIRECT (AUTO SURR/STREAM DIRECT) to select �AUTO SURROUND� and start playback of the source.1 If you�re playing a Dolby Digital or DTS surround sound DVD disc, you should hear surround sound. If you are playing a stereo source, you will only hear sound from the front left/right speakers in the default listening mode. � See also Listening to your system on page 35 for information on different ways of listening to sources. It is possible to check on the front panel display whether or not multi-channel playback is being performed properly. When using a surround back speaker, 2D+PLIIx MOVIE is displayed when playing Dolby Digital signals, and DTS+Neo:6 is displayed when playing DTS 5.1channel signals. When not using a surround back speaker, DOLBY DIGITAL is displayed when playing Dolby Digital signals. For other details, see Listening modes with different input signal formats on page 128. If the display does not correspond to the input signal and listening mode, check the connections and settings. 4 Use the volume control to adjust the volume level. Turn down the volume of your TV so that all sound is coming from the speakers connected to this receiver.

Using Phase Control
During multichannel playback, LFE (Low-Frequency Effects) signals as well as low-frequency signals in each channel are assigned to the subwoofer or other the subwoofer and the most appropriate speaker. At least in theory, however, this type of processing involves a group delay that varies with frequency, resulting in phase distortion where the low-frequency sound is delayed or muffled by the conflict with other channels. With the Phase Control mode switched on, this receiver can reproduce powerful bass sound without deteriorating the quality of the original sound (see illustration below).

Better sound using Phase Control and Full Band Phase Control
This receiver is equipped with the two types of functions that correct phase distortion and group delay: Phase Control and Full Band Phase Control. Activating Full Band Phase Control is strongly recommended because it also involves the effects of Phase Control. For details on each of these two features, refer to the following explanations.

Original sound preserved with no loss of clarity

� Rhythms with crystal-like clarity � Bass sound with no loss of depth � Sound of musical instruments with superb reality

Note 1 � You may need to check the digital audio output settings on your DVD player or digital satellite receiver. It should be set to output Dolby Digital, DTS and 88.2 kHz / 96 kHz PCM (2 channel) audio, and if there is an MPEG audio option, set this to convert the MPEG audio to PCM. � Depending on your DVD player or source discs, you may only get digital 2 channel stereo and analog sound. In this case, the receiver must be set to a multichannel listening mode (see Listening in surround sound on page 35 if you need to do this) if you want multichannel surround sound.
