Surround sound (Cubase only)
Radius
When using the Orbit Center control, the Radius encoder
allows you to control the distance of the sound source
from the center of the surround field (without changing the
angle).
An example:
The gray circle shows the theoretical path of the sound
source when orbiting the center. Since the sound source
cannot leave the pan area, it moves along the perimeter in
-
stead. At the maximum radius setting (a) the theoretical
path lies outside the pan area so that the sound source
stays on the perimeter all the time; at a smaller setting (b)
the circle is smaller and the sound source moves inside
the pan area in the corners.
Ö The Rotate Signal, Orbit Center, and Radius controls
are endless rotary encoders so that there is no limit as to
how far left or right you can rotate the sound source.
The LFE encoder
Use the LFE encoder in the plug-in panel to set the signal
amount sent to the LFE (Low Frequency Effects) channel.
You can also set this using the LFE level slider to the right
of the panner in the Mixer channel strip, or by typing in a
number in the LFE value field in the panner shown in the
extended Mixer view.
Ö The LFE channel is used as a full range channel, no
low-pass filtering is applied.
Center Distribution
The Center Distribution control is used to distribute part or
all of the center signal to the left and right front speakers.
For example, this can be useful in the following situation:
The center signal is panned directly to the center speaker
and the Center Distribution is set to 0
%. However, the
signal is too discrete for your liking, and you want to add
part of the signal to the left and right front speakers to
widen it. You can do this by raising the Center Distribution
value. At 100
%, the center source is provided entirely by
the phantom image created by the left and right speakers
and using a value in between you can distribute the signal
to the three speakers.
A blue line at the top of the surround field indicates the
distance up to which a phantom signal is added. If you po-
sition the source signal inside this range, the signal is sent
to all three channels.
Divergence controls
The three divergence controls (Front, F/R, and Rear) deter-
mine the attenuation curves used when positioning sound
sources for X-axis front, Y-axis (front/rear), and X-axis back.
If all three controls are set to 0
%, positioning a sound
source on a speaker sets all other speakers to zero level.
With higher values, the other speakers receive a percent-
age of the sound source.
Blue horizontal and vertical lines visualize the effects when
changing the divergence settings.
!
In terms of automation, the Orbit Center, and Radius
controls are not independent parameters as such. In
-
stead, a combination of different automation parame-
ters is used. For more information, see “Automation”
on page 225.
a) Radius = 141.4 b) Radius = 116.5
!
Note that for this to work, the front speaker configu-
ration needs to be symmetrical and there can never
be more than 3 speakers involved.
