AUTOCOM PRO MDX1400

15

The 

SC FILTER

 switch activates a highpass filter in the sidechain path and thus limits the influence of

low frequencies on the AUTOCOM PRO’s control processes.

16

The 12-digit 

GAIN REDUCTION

 meter indicates how effectively the gain is reduced by the compressor,

within a range from 1 to 30 dB.

17

The 12-digit 

INPUT/OUTPUT LEVEL

 meter informs you – depending on the setting of the I/O METER

switch – about the current input or output level, within a range from -30 to +18 dB. When the switch is

set to IN (engaged), the meter reads the input level, when it is OUT (not engaged), the output level is

displayed. The meter is referenced to the operating level (-10 dBV or +4 dBu) adjusted with the

OPERATING LEVEL switch.

2.3 Dynamic Enhancer Section

The 

PROCESS

  control  sets  the  available  amount  of  enhancement  between  Off  and  6.  Dynamic

enhancement allows you to replenish any high frequencies lost through the compression process for

absolutely natural sounding dynamics control. Enhancement is only added when compression is taking

place.
