SURROUND SOUND 211
Angle Mode
A sound field is displayed which extends in radial shape from the center of the circle. The
sound source is located on the central axis of this sound field. The loudspeakers are
aligned in a circle. The level shares of a sound source each routed to one channel are
determined by the angle ratio between the sound source and the loudspeaker as well as
the aperture angle of the sound field. If the angle of the sound source and the channel
correspond with each other (i.e. the middle axis of the sound field is pointing directly at the
loudspeaker: angle difference = 0), the level of this channel is highest. If the angle
difference increases, the level of this channel continuously decreases.
Example of use: Good localization of direction of movements (e.g. airplane passing, etc.)
Con: Not suitable for distance panning.
Width: Determines the size of the sound field aperture angle.
Soundfield character (Pan setup): The panning characteristics of a sound field can be
changed. Inver. Log. results in a larger angle aperture and shorter fades between the
loudspeakers. Log leads to smaller apertures angle and longer fade times between the
loudspeakers.
"Const. max. sum. output level" mode: If this is activated, the master level of all channel
outputs of the surround panorama module does not exceed the value entered here. If this
setting is activated in "Angle" mode, level drops in the sound field in the event of
movements are avoided in connection with large aperture angles.
Matrix Mode
The level of the input signal, which is sent to the individual surround busses, can be
entered directly in "Matrix" mode. Entering the values manually after double-clicking on the
numeric field does this.
Dragging the mouse over the level bars whilst keeping the left mouse button depressed
can also change the value. Fine-tuning is possible by additionally holding the "Shift" key
down.
