gml gml2020 Manual De Usuario
Integral to the superb quality of all GML products is the external power supply. No
piece of electronic equipment can operate as designed without an adequate power
supply; however, most contemporary processors do not feature a supply which can
provide clean, quiet power without unduly heating the device. The Model 9015 excels in
this respect, providing clean, quiet power for the many complex and sensitive circuits of
the Model 2020, while remaining cool and efficient. Internal supply topologies are
generally limited by board real-estate and thermal considerations and thus are almost
always exclusively of one or another of the switching topologies, which results in more
mains-induced noise and less ability to react to highly transient signal content or
extreme circuit actions. The internal power distribution scheme employed by the Model
2020 is also responsible--in concert with the external supply itself--for preserving the
highest audio quality throughout the many circuits of the High Resolution Discrete Input
Channel.

It is important to keep in mind that the noise performance of the Model 2020 varies with
operational settings. An increase in noise is to be expected when switching from the
'EQ Out' state to the 'EQ In' state. The reason for this characteristic is inherent to our
proprietary design, which places the control before all of the processing bands. This
gives our parametric equalizers two distinct advantages: first, potentiometer noise is
attenuated; second, the likelihood of internal overload is extremely remote, if not
impossible, even with 15 dB of gain available in each band. Interestingly, the most
dangerous condition for internal overload is experienced when using just a bit of EQ
with very high-level input signals. Similarly, the noise floor of the Model 2020 should be
expected to increase proportionally with gain and frequency in the Dynamics section
when that section is in-circuit. The big difference between GML units and non-GML
units comes not only in our design topology, but also in our component choices. In fact,
our topology is not really feasible with IC op-amps--they're always noisier than
discretes--and only works with our quiet, transparent discrete op-amps, which can
cleanly handle output signals up to +27.5dBu. One should expect the noise floor to
increase proportionally with gain, frequency, and "Q", in accordance with the laws of
physics.
