SURROUND SOUND 209
Pan L/R: Mono and stereo sources can be positioned in the surround panorama module.
The “Pan L/R” function determines how the mono and stereo signals can be positioned. A
distinction must be made between the types of signal. For more information please read
the chapter entitled “Stereo and mono signal processing in surround projects”.
Panorama Modes of the Surround Panorama Module
Soundfield Mode
In "Soundfield" mode the input signal is displayed as a concentric sound field. Each red line
corresponds with a 3dB drop in the sound field level. The loudspeakers are positioned in
such a manner that the distance from a single loudspeaker to a neighboring speaker
remains constant. This positioning permits a uniform distribution of the sound source
across all channels. Level ratios develop between the channels, which could not be
achieved in other modes.
Example of use: Very accurate localization, particularly for movements.
Con: Level conflicts, e.g. movements in a constant direction ("Angle" mode is more suitable
for this).
Width: Influences the sound field width of the loudspeakers.
Soundfield character (Pan setup): You can adjust the character of the soundfield.
"Invers. logar." results in a quick drop of the soundfield and thus short fades between
loudspeakers. "Logarithmic" results in a slow reduction of the soundfield and thus longer
transitions between speakers.
