ASTER FUNCTIONS
Phase
The "Phase" function shifts the phase of lateral and rear channels (L, R, sL
and sR) because up-converting introduces a negative tendency in L-R and
SL-sR correlation. This phenomenon is due to the fact that the correlated
part of the original stereo signal meets in the C channel.
The "Phase" function prevents this aspect by shifting the phase of the L-R
and sL- sR signals through only one variable. The variable is calibrated
from zero to one hundred percent and applies a phase shift modeled on the
physical angled distances of the loudspeakers.
Unit: Percent
Range: 100 % - 0 %
Iso Bal
The ISO balance function assures compatibility between the stereo and
multichannel formats. The difference between downmix and original stereo
signal is called "intermix". This intermix is inserted in the multichannel sig-
nal so that the downmix is mathematically identical to the stereo signal.
In order to be able to better integrate the intermix within the multichannel
stem, the ISO function separates the elements M (half sum) and S (half
difference) of the "Intermix". Element M is split between channels C and L-
R. Element S is split between the L-R pair and the SL-SR pair.

Master Level
This fader is used to attenuate the master output level of all channels.
Unit: dB
Range: 0 dB - -inf
