FX Com. (Effect Compression)
The FX Com. mode allows to switch off the DynaMaxx‘s perfectly automated dynamics
processing. In this mode a fixed release time of 60ms is applied, but the Attack time is still
automated. This mode increases the perceived loudness in comparison with the normal
Compression mode, and audible compression artifacts can be generated for creative
purposes.
The gain of the audio signal is restored back to normal shortly after the 60ms Release time
has passed, creating deliberate breathing and pumping effects. The LED display provides a
visual impression of the increased processing speed. The higher the CompressION control
setting, the more intense those effects will become.
Lim. (Limiter)
In limiter mode the DynaMaxx only processes the peak levels but leaves, in contrast to the
compressor mode, the gain structure of low-level signals unchanged. Limiter mode is useful
when working with ‘clipping-sensitive’ media or units and it improves the utilisation of digital
headroom as well as the bit resolution.
The COMPRESSION control sets the threshold in LIM. mode. The further the control is moved
clockwise, the lower the threshold, and all signals above the threshold will be submitted to
the limiting process as a fixed ratio of ∞:1.
The limiter is based upon a soft-knee limiting characteristic. In comparison with hard limiting
characteristics, soft limiting
is more unobtrusive and
sonically more natural.
When a peak level exceeds
the threshold, the level isn’t
suddenly reduced, as would
be the case with a hard
limiting characteristic, but
rather the soft limiting starts
its processing earlier. This
way, peak levels are limited
far more smoothly once the
threshold is reached. The
following measurements
illustrate various soft-knee
limiting curves:
On
With the ON button you can turn the device on or off. The ON button is illuminated when the
device is active.
Relay hard bypass circuits ensure signals to be directly switched from input to output in the
case power failures – this “Power Fail Safety“ feature guarantees signal flow in any situation.
If you operate a DynaMaxx module in LINK-Mode, the ON button of the master module
controls both modules. The LINK and ON buttons of the DynaMaxx module that is currently in
LINK mode will thus be illuminated as well—although they have not been activated.
