BASICS
Thresh
Stereo Compression
In order to get a first impression of the sonic qualities and the control characteristics of the alpha
compressor, only the controllers highlighted in the figure are used. The functions that are cur-
rently not needed should be deactivated (related LEDs do not glow). Et voilà: We have a classic
linked stereo compressor!
A track with a broad dynamic range is the best material for a first test. Just start playing with the
threshold, attack, release and ratio parameters of the left channel in order to get to know the con-
trol behavior of the compressor. Allow yourself to take some time for this, as the understanding of
the basic control characteristics is the most important condition for perfect results.
Keep having a look at the gain reduction meters from time to time. No doubt: the ear is the de-
cisive benchmark. Just consider the optical information as a supporting means to evaluate the
compression process (fast/slow, strong/weak, etc.).
The levels of the compressed signals can be made up by adding an appropriate amount of ampli-
fication with the gain controllers. Since the link function will only affect the control voltage of the
compressor, the gain controllers of both channels should be set to the same values in stereo link
mode. For instant A/B comparisons just push the active button.
Note: If the threshold controller produces too little gain reduction when turned hard right or too
much of it when turned hard left, please go to page 26 and see how to adjust the internal thresh-
old.
