Feed Forward
This function makes it possible to switch the junction of the sidechain alternatively behind (feed-
back) or in front (feed forward) of the actual compressor section. This has an enormous effect on
the character of the compressor.
Again, our drum loop can be used for demonstration: While processing in feedback mode is
smooth and even, switching into feed forward mode will result in a clearly more aggressive and
harder kind of compression.
From the technical point of view this function mainly influences the characteristic curve of the
ratio value. In feedback mode it goes up to a moderate Ratio of 1:2.5. In contrast, the feed forward
mode provides much higher values that also allow limiter settings and even negative ratios (i.e.
loud signals will be reduced even more). Thus, small changes in dynamics can generate a high
amount of gain reduction.
The values of the attack controller will also change noticeably in feed forward mode, as they will
become almost twice as high as the value shown on the scale.
Transformer
Each of the two channels features an additional transformer that can be switched into the signal
chain after the mix stage. In principle, these are classic output transformers, but here they are not
used for balancing and galvanic isolation, but as an additional means of sound shaping.
If you like to add that certain amount of ‚iron‘ to your sound, just push the transformer button and
there you are. Because of the mastering approach of the alpha compressor this feature is much
more a subtle audio shaping feature than a glaring sound effect.
In stereo mode, the buttons for both channels should be activated or deactivated at the same
time. Depending on the source material and personal taste, you can, however, add the transform-
er sound to single channels when working in M/S mode.
