Figure 2–5: Ellipse with approximately 13
° phase error
If the ellipse closes to a single line, the LEFT and RIGHT channels are in phase
as long as the line is within 45
° of the L=R axis.  The line may tilt if the
amplitudes are unequal.  A line within 45
° of the L=–R axis indicates the
channels are out of phase.
The 760A’s pattern display provides a graphic representation of the stereo
signal’s overall energy distribution.  The pattern orientation tells you at a glance
whether the present mix is balanced or concentrated to either side.  Figures 2–6
and 2–7 illustrate different energy distributions.
