Figure 2-2
Setting console preamp gain
6.
With the room quiet, raise your console preamp gains until the Model E-2’s green
level
LEDs stay illuminated.
The
level
LED illuminates green when the input level is within the acceptable
range for automatic mixing and flashes red to indicate clipping. There should be
enough gain ahead of the Model E-2 to maintain the green LED at all times.
NOTE:
When the green
level
light extinguishes, the channel is in a downward expansion mode
to avoid feedback. This condition should be avoided because the smooth ambience that
characterizes Dugan automatic mic mixing is lost.
Figure 2-3
During ambience with 4 mics,
auto mix gain
displays should hover around -6 dB
7.
Adjust your console’s preamp gains so all LED meters float at about the same gain
when no one is talking. This procedure assures smooth automatic mixing.
