Phase Control technology provides coherent
sound reproduction through the use of phase
matching
1
for an optimal sound image at your
listening position. The default setting is on and
we recommend leaving Phase Control
switched on for all sound sources.
•Press
PHASE
to switch on phase to switch
the Phase Control on or off.
Using surround back channel
processing
You can have the receiver automatically use 6.1
or 7.1 decoding for 6.1 encoded sources (for
example, Dolby Digital EX or DTS-ES), or you
can choose to always use 6.1 or 7.1 decoding
(for example, with 5.1 encoded material). With
5.1 encoded sources, a surround back channel
will be generated, but the material may sound
better in the 5.1 format for which it was
originally encoded (in which case, you can
simply switch surround back channel
processing off).
• With a 7.1-channel surround system, audio
signals that have undergone matrix
decoding processing through surround
back channel processing to which the Up
Mix function is added are output from the
surround back speakers.
• Press , then press SB CH
repeatedly to cycle the surround back
channel options.
Each press cycles through the options as
follows:
• SB ON –
Matrix decoding processing for
generating the surround back component
from the surround component is turned on.
• SB AUTO – Matrix decoding processing for
generating the surround back component
from the surround component is switched
automatically. Matrix decoding processing
is only performed when surround back
channel signals are detected in the input
signals.
• SB OFF – Matrix decoding processing for
generating the surround back component
from the surround component is turned
off.
Note
1 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.
• 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 the headphones are connected.
