Scaling
The Scale controls allow you to control the horizontal (Width) and vertical (Depth) expansion of the sound source. 100 % corresponds to the complete width or depth of the surround field. If you reduce both values to 0 %, the distance is reduced to zero and all source channels are centered in one spot.

These controls influence the perception of spatiality and ambience, as well as the traceability of signals.
At 100 % you get a very transparent, clear sound that conveys much spatiality.
At 0 % the signal is less transparent and movements cannot be traced easily.
Note
The Depth parameter is only available for configurations with front and rear channels.
