The large surround panner has some sliders at the bottom that the medium
surround panner doesn’t have, except for the LFE Send slider, which the medium
panner has. Except for the sliders, the large and medium surround panners have
the following controls:
• Angle and Focus marker—a small sphere that you can drag in any direction to
both control and display the following two parameters:
• Angle—this is the perceived angle of the sound source as it differs from
the position directly in front of the listener. The scale is 0 to 180 degrees
on the listener’s right, and 0 to -180 degrees on the listener’s left. 0 means
the sound is coming from directly in front of the listener, and plus or
minus 180 degrees means that the sound is coming from directly behind
the listener.
• Focus—this is the perceived distance of the sound source from the center
of the circle on a scale of 0 to 100, 0 meaning the center of the circle, and
100 meaning the perimeter.
• Width markers—these are two smaller spheres equidistant from the Angle
and Focus marker. Their distance from each other and from the front of the
circle shows the Width value (see definition below). You can also drag the
Width markers to control Angle and Focus.
• Speaker icons/squares—each surround channel is represented by a speaker
icon in the large panner, and a white square in the small panner. The large
panner also has a corresponding volume level in dB directly in front of each
icon. The position of each speaker icon shows you each speaker’s position in
the surround mix. Clicking a speaker icon or square mutes the corresponding
channel, causing the icon or square to become grey. Double-clicking the icon
solos its channel, turning the icon green.
• Angle slider (large panner only)—this slider both displays and controls the
angle value.
• Focus slider (large panner only)—this slider both displays and controls the
focus value.
