The Output control sets the output gain of the Levelar. When the
control is fully counterclockwise, the output level of the Levelar is
attenuated by -83dB. Turning the control clockwise adds gain
(sometimes called “make-up” gain). Since levels can be decreased
when compression is applied, the Levelar has the ability to apply
gain to bring the processed signal back up to unity (same as input
level). To properly set the output level, adjust the control while
switching between Active and Bypass. When these two levels are
equal in volume, the output control is set properly.

The four-LED meter is provided to give a visual indication of how
much compression is taking place. The Threshold LED will light
when the input signal reaches the set threshold level. The remain-
ing three LEDs indicate how much the signal is being compressed.
Their values are -2dB, -3dB and -6dB.
