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, 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 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 MULTI CH IN input is selected.
– When the HDMI audio output parameter is set to THROUGH in Setting the Audio options on page 60.
