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.
