Press S.DIRECT (STREAM DIRECT) to select 'AUTO

SURROUND' and start playback of the source.

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 28 for

information on different ways of listening to sources.

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.

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.

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).

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 28 if you need to do this) if you want multichannel surround sound.

2 • Phase matching is a very important factor in achieving proper sound reproduction. If two waveforms are 'in phase', they crest and trough together,

resulting in increased amplitude, clarity and presence of the sound signal. If a crest of a wave meets a trough (as shown in the upper section of the diagram

above) then the sound will be 'out of phase' and an unreliable sound image will be produced.

• The PHASE CONTROL feature is available even when the headphones are plugged in.

• If your subwoofer has a phase control switch, set it to the plus (+) sign (or 0°). However, the effect you can actually feel when PHASE CONTROL is set

to ON on this receiver depends on the type of your subwoofer. Set your subwoofer to maximize the effect. It is also recommended you try changing the

orientation or the place of your subwoofer.

• Set the built-in lowpass filter switch of your subwoofer to OFF. If this cannot be done on your subwoofer, set the cutoff frequency to a higher value.

• If the speaker distance is not properly set, you may not have a maximized PHASE CONTROL effect.

• The PHASE CONTROL mode cannot be set to ON in the following cases:

– When the PURE DIRECT mode is switched on.

– When MULTI CH IN is selected.

– When the HDMI audio output parameter is set to THROUGH in Setting the Audio options.
