gml gml8200 Manual De Usuario
Though the front panel controls seem very intuitive to the initiated and experienced
audio engineer, the circuit design behind these controls is anything but simple and
straightforward. The GML 8200 features exemplary input and output buffering circuits in
addition to the actual equalization circuits. It is important to keep in mind that all circuits
in any device necessarily alter the sonic character of any complex signal, though these
colorations have been meticulously minimized in the design of the 8200. Many
contemporary equalizer designs are not sensitive or wary of this aspect of audio
electronics and thus require some amount of alteration to compensate for this additional
spectral signature induced by the unit itself.

Interestingly, care has also been taken--as in all aspects of the GML 8200--to select the
highest quality components, from the potentiometers on the front panel to the smallest
passive elements. This attention to detail partially elucidates the quality found in the
GML 8200 Parametric Equalizer. These component choices, coupled with superior
design and a proclivity towards innovation, combine to make the GML 8200 Parametric
Equalizer the most powerful, flexible, and transparent equalizer ever designed.

Another feature that distinguishes the GML 8200 from the myriad of other commercially
available equalizers is its inherent dynamic range, which allows for the addition of 15 dB
of gain in multiple frequency bands simultaneously without even a hint of distortion or
loss of detail and authority. This amazing power is due in large part to the GML
propensity to design all audio circuits from discrete components. Discrete designs,
when executed properly, help to preserve not only sonic integrity and musicality, but
also to allow for the widest dynamic range through the entire signal path, thus
eliminating many sonic compromises and limitations. Not only do these discrete
structures--and the GML 9202 discrete opamp in particular--sound better than their
integrated counterparts, they also offer the ability to design for higher signal levels
internally, while also optimizing dynamic range by providing a low noise floor.

An additional benefit of the discrete circuit topology used in the GML 8200 Parametric
Equalizer is increased bandwidth. Not only does this significant extension--of both high
and low frequencies--provide for more detail and realism; it also ensures a greater
degree of linearity in the traditional audio spectrum (20 Hz to 20 kHz) by locating
bandwidth poles superceding these commonly-accepted limits. Indeed, the frequency
response of the Model 8200 is well within +/- 0.1 dB from below 10 Hz to well above 80
kHz, while the +/- 3.0 dB response exceeds the ability of most audio test apparatus to
measure.
