vs. frequency response, sharp cutoff.
Phase (Polarity)
Touching this control on the front panel touch screen (or the
remote) will invert the absolute phase (polarity) of the audio
signal. This is the same thing as reversing the loudspeaker
inputs, placing + to – and – to +. Phase reversal happens on
many recordings, sometimes even within the same CD or DVD.
If the track sounds a little “off” try reversing the phase with this
control to see if the CD track gains a bit of proper perspective. If
it does, chances are good that it was recorded out of polarity.
