in the following order: HDMI; DIGITAL; ANALOG.
• ANALOG – Selects an analog signal.
• DIGITAL – Selects an optical or coaxial digital signal.
• HDMI – Selects an HDMI signal. 2

• HDMI is not assigned by default. To select an HDMI

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).
Phase Control OFF
• Rhythms blurred and difficult to hear
• Bass sound with loss of depth
• Sound of musical instruments with no reality
Phase Control ON
• Rhythms with crystal-like clarity
• Bass sound with no loss of depth
• Sound of musical instruments with superb reality
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.
2 When 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.
