3-Knob mode lets you pan discretely between
speakers. For example, when panning front-left
to rear-right in 3-Knob mode, audio will be
heard from just those two speakers (assuming
full divergence is in effect).

By comparison, in X/Y mode a diagonal pan
may result in audio being heard in some or all
channels.
X/Y mode
Panning and metering in X/Y mode
The difference is that 3-Knob mode pans dis-
cretely between the front and rear position of
the panning trajectory, while X/Y mode panning
takes place in the full 360° Panning Grid. Diver-
gence and Center Percentage are variable in
both Panning modes.
