Mackie Stereo and Mono Side chain Compressor 사용자 설명서

The reduction meter along the right edge of the 
screen shows the overall reduction in output 
level due to the compressor operation. If you 
are using expansion, then there will be an in-
crease in output level. This meter will help you 
add or adjust the makeup gain.

The meter reads 0 dB whenever the input is 
below threshold, and moves down as the input 
level goes above threshold and gain reduction 
starts. 

The meters below the graph show the input lev-
els of the signals going into the compressor and 
the left and right output levels.

The stereo compressor takes its input from a 
mixed sample of the left and right, so there is 
only one input meter. Its compressor action 
then works equally on the left and right of your 
stereo track.

It is interesting to see the position of the 
threshold with respect to the input level meter, 
and to see the output meters. Some say they are 
almost hypnotic, and you can even predict Lotto 
numbers.

The small boxes at the right of the input and 
output meters are the overload LEDs. They 
light if the signal goes above 0 dB, and this 
should be avoided. Most little red lights which 
come on should be avoided, like that one in the 
car which says "Oil." 

You can generally get rid of clipping by backing 
off the makeup gain slider slightly, or by engag-
ing the Soft Clip switch (see the previous page).
