Using the Mono-to-Surround Panner
If the source input is set to mono, the Mono-to-Surround Panner appears.
The most obvious element of the Surround Panner window is the surround field. You can
use it to control the surround routing of the input signal to the speaker outputs. The level
sliders and fields (shown below the surround field) provide independent control of the
Center and LFE channel levels. The extended parameters allow you to precisely control
the separation between channels.

Surround Field
The surround field consists of the following:
• Two real time display fields, for angle and diversity. You can directly interact with these
fields by using the mouse as a slider.
• A circular grid, comprised of four concentric circles, divided into eight segments, each
of 45 degrees. The outer circle represents the minimum amount of diversity, with the
center circle representing the maximum amount of diversity.
• A further circle encloses the grid. This is actually the Diversity/Angle display (or meter,
if you prefer). As the diversity (or angle) changes, a portion of the diversity display is
highlighted.
• A square is overlaid on the grid. This is an indicator of the separation between left and
right channels, and also front and rear (surround) channels. You can directly interact
with the corners or edges of this separation square by dragging them. Alternately, you
can use the sliders or display fields in the lower section of the Surround Panner window.
