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 

, then press PHASE to 

switch the Phase Control on or off.

Listening with Acoustic 
Calibration EQ

You can listen to sources using the Acoustic 
Calibration Equalization set in 

Automatically 

setting up for surround sound (MCACC)

 on 

page 29. Refer to these pages for more on 
Acoustic Calibration Equalization. 

•

While listening to a source, press 

, then press EQ to switch the 

Acoustic Calibration EQ on or off.

The MCACC indicator on the front panel lights 
when Acoustic Calibration EQ is active.

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.

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.

2 You can’t use Acoustic Calibration EQ with Stream Direct mode and it has no effect with headphones.
