AGC, Plosive, & Proximity Effect
Control
This control uses a potentiometer to simul-
taneously adjust the parameters for the A utomatic Gain
Control, and the Plosive/Proximity Effect Control. Use
the Phantom Phillips tool to turn the pot.
Settings: 1:1 to 4:1 ratio
Control: Turning the pot all the way to the left, or coun-
terclockwise, turns these functions off. Turning the pot
all the way to the right, or clockwise, maximizes the effect
of the AGC and Plosive/Proximity Effect Control.
Indicator: None.
For best results talk into the mic while turning this pot
until you get the desired results. Turn the pot to the
right, or clockwise, to get:
• Increased gain reduction when someone gets too
close to the mic and speaks loudly.
• Increased protection from those loud plosive
pops associated with certain hard consonants, like
"p" or "t" or "k".
You may have a variety of people using the SGM mi-
crophone. In this case you will have to chose a setting
that protects your system from those who get too close
to the mic, and still allows for sufficient gain for normal
speakers, and for those who speak in a very quiet voice.
Higher settings may require an increase in gain at the
mixer to maintain nominal level.
