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.
Phase Control technology provides coherent sound reproduction through the use of phase matching for an opti-
mal sound image. The default setting is on and we recommend leaving Phase Control switched on for all sound
sources.
1 Press to the receiver operation mode.
2 Press PHASE (PHASE CONTROL) to switch on phase correction.
The PHASE CONTROL indicator on the front panel lights.
Note
! 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, then the sound will be ‘out of phase’ and an unreliable sound image
will be produced.
! For discs created with standards other than Phase Control, the LFE channel is delayed upon recording in the
first place. Phase Control Plus function corrects for phase shifting on such discs. For instructions on setting
the Phase Control Plus, see Setting the Audio options on page 59.
! If your subwoofer has a phase control switch, set it to the plus (+) sign (or 0º). 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 headphones are plugged in.
— When the PURE DIRECT mode is switched on.
— When the HDMI audio output parameter is set to THROUGH in Setting the Setting the Audio options on page
59.
