Better sound using Phase Control

This receiver’s Phase Control feature uses phase

correction measures to make sure your sound source arrives at the listening position in phase, preventing unwanted distortion and/or coloring of the sound.

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• This receiver can only play back Dolby Digital, PCM (32 kHz to 192 kHz), DTS (including DTS 96/24) and WMA9 Pro digital signal formats. The compatible signals via the HDMI terminals are: Dolby Digital, DTS, WMA9 Pro, PCM (32 kHz to 192 kHz), Dolby TrueHD, Dolby Digital Plus, DTS-EXPRESS, DTS-HD Master Audio, SACD and DVD Audio (including 192 kHz). With other digital signal formats, set to ANALOG (the MULTI CH IN and TUNER).

•You may get digital noise when a LD or CD player compatible with DTS is playing an analog signal. To prevent noise, make the proper digital connections (page 28) and set the signal input to DIGITAL.

•Some DVD players don’t output DTS signals. For more details, refer to the instruction manual supplied with your DVD player.

2When the HDMI audio output parameter is set to THROUGH, the sound will be heard through your TV, not from this receiver.

3• This is useful if you find there is a slight delay before AUTO recognizes the PCM signal on a CD, for instance.

•When PCM is selected, noise may be output during playback of non-PCM sources. Please select another input signal if this is a problem.
