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
Configuration menu.

Your instrument can also display the surround sound listening environment. The
following procedures help you get started.
1. Open the audio display in one tile and select the input containing the surround
audio. (See page 160, To set up an audio input.)
2. Select Aux Display and then select Surround Sound Display. Press SEL or
the right-arrow key to turn the phase display on.
3. Set the Audio Input to match the signal that you are checking.
NOTE.
If you want the level bars labeled with their surround sound channel
names instead of channel numbers, select Srnd (Surround) when you configure
the audio inputs. (See page 160.)
You can also set the Dolby Listening mode. (See page 168.)
4. Set the surround Dominance indicator to ON or OFF.
