You can switch the compressor
between compression and limiter.
Please note that, as mentioned above, the ratio by program regulation depends on the
program.
3) Pre-filter
There are different types of EQ. Each is
treated as an independently built-up
circuit.
- active A/B
This is an emulation of an analogue filter module which operates with positive and negative
feedback loops. Here, A and B differ from one another in the corner frequencies of the
bands. B is optimized for use with speech or singing.
- passive A/B
This circuit corresponds to the classic Baxandall network and is comparable to stereo
systems and some guitar amps, whereby type B is slightly rounder in the mid range than
type A. This circuit corresponds with the classic Baxandall network and is comparable to
stereo systems and some guitar amps, whereby type B is slightly rounder in the mid range
than type A insofar as the basses and highs are further apart by spectrum, and the mid
range is further accounted for. Variant A is intended for general applications, filter B is
optimized for vocals. The mid range, which is also available here, is not available in a
Baxandall network and has been made possible in the existing circuitry as cascading low
and high-pass sections, much like in common passive equalizers. The interesting thing
about this setup is the effect the individual steps have on the entire phase response, which
contributes a lot to the unique sound of this circuitry.
- guitar passive
Classic circuits such as on Marshall/Fender amps. The parameters are highly dependent
on each other (more highs = less bass, mids are also influenced). Much like with general
"passive" circuitry, here too you can find complex phase responses via the variable mixing
in of individual branches of the filter network with the typical charm of such a classical
design.
