mage Control
X
-Verb comes with an innovative Stereo Image interface which performs Stereo width, Phase, Left/Right
c
hannel swapping, and Surround Processor compatible L-R – R-L operations. The control is located in the top
r
ight-hand corner of the window.
The image can be rotated by 360° in either direction. A number of image presets are included – click
on the box to the right of the Image label and select one from the drop-down list which appears
(shown left).
Note that the angle of the Image controller is not the position of the signal within the spectrum. In
essence, the display works as follows:
As the Image controller moves left, the level of the Left signal is reduced in the Right component,
and vice versa. As the image moves up, the level of the Left signal in the Left component is reduced, as is the level
of the Right signal in the Right component.
The diagram below illustrates the ‘angle’ associated with each preset, and the subsequent stereo/surround imaging. The blue
boxes indicate the stereo image, the red and green boxes indicate the actual signals on the left and right channels
respectively, and the image preset name is shown in bold. The diagram to the right indicates what is happening as you turn
the image controller clockwise.
The symbols surrounding the image control indicate the following:
Surround image
Stereo image
Mono image
Note that often two of these symbols will be ‘lit’, as the image moves between them.
X L/R swap
L/R L and R symbols represent the phase of the left and right signals in the left component: The lower ones indicate
when that component of the signal is in phase, and the upper ones indicate when it out of phase. In other words,
the signals are in phase with each other when they are in the same row, and out of phase when they are in the
same column.
Ø Signals are more out-of-phase than in-phase
