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 optimal sound image. The default setting is on and we recommend leaving Phase Control switched on for all sound sources.

1Press to the receiver operation mode.

2Press PHASE CTRL (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.

!The PHASE CONTROL feature is available even when the headphones are plugged in.

!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 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 46 .
