Name
The loudspeakers are designated with defined abbreviations: “L” (left), “C” (center),
“R” (right), “Ls” (left Surround), and “Rs” (right Surround).
Volume
A level indicator appears next to each loudspeaker and shows the value of the level
share that the sound source is transmitting on this Surround bus. For the stereo
modes the total of the level of both sources is always shown. If "Shift" is held down
and the mouse is clicked on a source, only the value for this source will be shown
briefly.
Sound field
The input signal is presented as a field made of concentric circles. Each red line
corresponds to a level-gradient of 3 dB in the sound field. The loudspeakers are
arranged in such a way that the distance between each loudspeaker and its neighbor
is constant. This arrangement makes a uniform distribution of the sound source
possible to all channels. Level relationships are created between the channels that
cannot be achieved in other modes.
Settings
Surround active
Activates the twin-channel Surround mode.
In the deactivated state the stereo position can only be determined via the control
elements in the track box or the mixer.
Pan L/R
This determines the way in which the left-hand or the right-hand channel is placed in
the Surround field. For the individual cases, please read the section on “Stereo and
mono signal processing with twin-channel Surround”.
Width
Affects the extension range of the loudspeakers.
Center
The parameter controls the share of the center in the distribution of the sound source
to the front channels. In certain working ranges (e.g. film sound) it is customary to
reserve the center channel for dialog and to mix music and noises without share in the
center. A signal positioned exactly in the middle is reproduced in the 5.1 format with
Center = 100% exclusively through the center channel, or with 0% exclusively as a
phantom sound source through the channels L and R. This parameter is often also
described as divergence.
