6. Check for Phase correlation of the
signals, noting the following:
Phase correlation meters are located
under the appropriate bars and
one is duplicated under the phase
display.
For correlated signals, the indicator
will be green and will move to the
right.
For uncorrelated signals, the
indicator will be yellow and will tend
to stay in the middle.
For anticorrelated signals (one goes
up when the other goes down), the
indicator will be red and will move
to the left.
Usage Notes
The Lissajous or phase display is a plot
of one channel against another on an
orthogonal pair of axes.
Soundstage plots the two channels
at 45 degree angles, with the mono
combination appearing on the vertical
axis, like a left-right image in a studio.
X-Y plots left-channel data on the
vertical axis and right channel data on
the horizontal axis, emulating the X-Y
display of an oscilloscope.
The following response times of the correlation meters can be set from the Con fi guration menu.
