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 (see illustration below).

Phase Control technology provides coherent
sound reproduction through the use of phase
1
matching 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.

SETUP
• Press PHASE (PHASE CONTROL) to switch
on phase correction.
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.

mode, Front Stage Surround Advance mode. It is also unavailable if the surround speaker is set to NO in Speaker setting on

Using Virtual Surround Back
(VSB)
Selecting this mode allows you to hear a
virtual surround back channel through your
surround speakers. For example, you can
choose to listen to sources with no surround
back channel information (for example, 5.1
encoded material) with emulated 6.1
encoding (VSB ON). Sometimes the material
may sound better in the 5.1 format for which it
was originally encoded. In this case you can
simply switch it off (VSB OFF).
Depending on the input signal and the
Listening Mode, the Virtual Surround Back
mode may not be effective.
