Make-Up Gain
The MAKE-UP GAIN control compensates for any level decrease when applying COMPRESSION.
The higher the processing intensity the lower the overall output level, the more Gain will be
required to restore the same peak level.
Turn the MAKE-UP GAIN control clockwise until the peak level of the input is the same as the
peak level of the output. Use the GAIN REDUCTION LEDs for a precise adjustment. The control
has a range of 20dB.
If the DE-COMPRESSION mode is activated, the MAKE-UP GAIN control compensates for the
increase in peak level. Note that in this mode, turning the Gain control clockwise decreases
the output level.
Gain Reduction LEDs
The 10-digit LED ladder meter is capable of displaying gain changes to a resolution of 1dB over
the range -1 dB to -14 dB.
When applying COMPRESSION to the audio signal, the LED meter displays the amount of gain
reduction taking place. From here you can see how much gain to compensate for with the
MAKE-UP GAIN control.
When the DE-COMPRESSION mode is activated, the LED display shows the gain increase
imparted to high-level signals.
DE-COM. (De-Compression)
The De-Compression function inverts the operation of the compressor to produce new
dynamic headroom, which may be used to increase the dynamic range of a (previously over-
compressed) signal.
The process may also be used to expand the dynamic range of other sources, such as drum
or synthesizer samples. Especially when creating loops, overcompressed samples can
result in lifeless sounds. With the DynaMaxx you can simply de-compress the signals again.
Interesting effects can also be achieved by applying different settings to the channels of a
stereo source.
IMPORTANT: While MAKE-UP GAIN increases the output level in standard mode, this function
is also inverted in DE-COMPRESSION mode – turning the control clockwise reduces the output
level.
The following diagrams show different characteristic curves in DE-COMPRESSION mode. If
the Limiter is activated in DE-COMPRESSION mode, the intensity of processing is increased
remarkably. Especially peaks are expanded more intensively.
