Power Balance History
Figure 3.48: Power Balance History
The Power Balance History compares the power balance between the two input channels as a function of time.
When the power level on the first input channel is greater than the second input channel the display turns
green and shifts above the centerline. When the power level on the second input channel is greater than the
first input channel, the display turns red and shifts below the centerline. The length of the indicator expresses
the difference in power between the right and left sides as a percentage of the total power present in both
signals. The light grey lines appear once per second as the history scrolls to the left. This meter is very helpful
for precisely identifying the aspects of mixes that don’t have a natural flow of energy between the left and
right channels. It is also great for power-balancing natural stereo recordings and two channel measurements
of equipment.
Lissajous Phase Scope
Vectorscope and X-Y modes
The Lissajous Phase Scope is equivalent to an oscilloscope running in either vectorscope

or X–Y mode
