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
matching
1
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.

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.
