compressors have the same established VCAs (voltage controlled amplifier), but they all
sound different and influence a signal, an entire production (or even a genre) with their
"signature sound". We see it as our task to put at your disposal a certain acoustic variation
with our dynamic tools in the digital world.
The two methods of the am-track can be selected using the switch 'vca / vintage':
VCA mode
In "VCA" mode, the parameter selection and the circuitry's design
correspond to a modern compressor with a VCA element as the
control circuit and a forward automatic gain control in the detector
section ('feed-forward design', that is, the controlling signal for level
reduction is taken from the input signal).
The typical basic sound for this category is accurate, largely neutral and, in
relation to the adjustable parameters, easily predictable.
In "VCA" mode the control signal is tapped at the input where it firstly executes a
controllable low-cut (which can be set up via "detector hp freq" in "Expert" mode). The
filter makes sure that deep-frequency signals have less influence on the adjustment
settings; a popular trick for more power, for example, when using drums in a sub-group.
The filtered signal then arrives at the detector. With the forward gain control, previously set
parameters apply fully and affect the adjustment settings immediately.
In contrast to this, there is a "feedback" method, which provides a second compressor
mode.
