When set to DIGITAL, HDMI or AUTO (only selected
DIGITAL or HDMI), the indicators light according to the
signal being decoded, as follows:
– 2 DIGITAL lights with Dolby Digital decoding.
– 2 DIGITAL PLUS lights with Dolby Digital Plus
decoding.
– 2 TrueHD lights with Dolby TrueHD decoding.

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, TUNER and PHONO).
• 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 35) 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.

Better sound using Phase Control and
DISP
Full Band Phase Control
This receiver is equipped with the two types of functions
that correct phase distortion and group delay: Phase
MEMORY
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 the other 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).
