6. With the room quiet, raise your console preamp gains until the Model E-3’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-3 to maintain the green LED at all times.
NOTE: When the green light goes out, the channel is in a downward expansion mode to avoid
feedback. This condition should be avoided because the smooth ambience that charac-
terizes Dugan automatic mic mixing is lost.
