gml gml2032 Manual De Usuario

Integral to the superb quality of all GML products is the power supply, an internal power
supply in this case.  No piece of electronic equipment can operate as designed without
an adequate power supply; however, many contemporary processors do not feature a
supply that can provide clean, quiet power without unduly heating the device.  The
Model 2032 internal supply excels in this respect, maintaining the ability to deftly react
to highly transient signal content and extreme circuit actions. While the absolute lowest
noise performance can best be achieved with an external power supply, this highly
regulated low-noise linear design minimizes the compromises in order to yield the
savings in space and cost that can derive from an internal supply topology.  Utilizing a
custom toroidal power transformer and precision regulators in a new design with
meticulous layout, the net difference in preamplifier noise is approximately 1dB, while
no increase in noise for the filter or equalizer is discernable. The internal power
distribution scheme employed by the Model 2032 is also responsible for preserving the
highest audio quality throughout the many circuits of the Microphone Preamplifier /
Parametric Equalizer.

Please note: The Model 2032 does not include a power On/Off switch; the unit is “on” when AC line
voltage is applied to the rear panel IEC socket.  Ensure proper IEC inlet settings  (110V / 220V) before
applying power to prevent damage.

It is important to keep in mind that the noise performance of the Model 2032 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
GML’s proprietary design, which places the control before all of the processing bands.
This gives GML 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.  Notably, the most
dangerous condition for internal overload is experienced when using just a bit of EQ
with very high-level input signals. The big difference between GML units and non-GML
units comes not only in design topology, but also in component choices.  In fact, the
GML parametric topology is not really feasible with IC op-amps--they're always noisier
than discretes--and only works with quiet, transparent discrete op-amps such as the
GML 9202, 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.
