The Full Ranger EQ Module is a graphic equalizer for processing
the entire frequency range with passive coil filters in eight bands. It
employs bell filters, each with individually optimized bandwidths,
boost and cut values.
The concept of the Ranger EQs for the RackPack modular system is
characterized by two decisive features that separate them from tradi-
tional designs.
First there is the basic idea of specialized modules for typical instru-
ment or vocal ranges. This follows a consistently musical approach,
but also the design of each filter is based upon musical demands
alone. The Full Ranger makes the necessary exception in this concept
to offer a module that can be both an all-round module for process-
ing of all instrument and vocals and an overlapping module to comple-
ment the specialized Ranger EQs.
The second characterizing feature follows the idea of a modular design
and affects both the filter technology and the user interface. Why did
we chose a graphic EQ design? For a fully parametric EQ with all neces-
sary controls there would be space for just one band on the module
front. Our graphic EQ offers eight bands—a bandwidth control is less
important, and different EQ modules can be combined to configure a
large and, if needed, complex EQ system.
But a traditional graphic EQ with an active filter design did not seem to
match our idea of a holistically musical approach. We decided for a rare
technical solution: the combination of passive filters with a graphical
user interface. Based upon individually specified, custom-made coils,
these filter designs convince with outstanding musical qualities.
Finally, the general advantage of modular systems becomes clearly
obvious when planning individual systems: A vocal recording channel
with RackPack modules can be configured in very specific ways, while
a complex EQ system may have a completely different focus.
