On the surface it is not eminently evident just how much "new" design is represented in
the Model 2020 High Resolution Discrete Input Channel. Indeed, the EQ and Dynamics
sections have been barely modified from the reference-standard Model 8200 Parametric
Equalizer and Model 8900 Dynamic Gain Control and even the Model 8300
Transformerless Microphone Preamplifier is largely copied herein. The design
innovation, however, of the Model 2020 lies, at least partially, in the confluence of these
diverse parts into a cohesive and extremely powerful whole.

The most notable and noticeable additions to the aforementioned GML legacy products
embodied in the Model 2020 are in the Input section. The innovative inclusion of
multiple inputs, new to the GML line, certainly adds to the allure of the Model 2020,
while the completely original M/I input circuitry represents a welcome addition to the
GML repertoire. An extremely wide range of gain settings for all three input types has
rarely, if ever, been implemented--this feature alone lends much vitality to the unit.

Metering has often been an area of design where changes have often been
recommended, especially for the mic preamp. The Model 2020 Input meter meets
these expressed needs elegantly over a wide range of signal levels. This entirely new
circuit is implemented using a building-block approach instead of the more common all-
in-one metering IC solution, which tends to be quite limited, especially in terms of
transient response, variable segment fade time, and especially dynamic range.

The routing functions of the Model 2020--both the Input Source and Routing switches--
complement the various processing blocks, providing a great deal of flexibility. The front
panel capacity to switch amongst the three inputs also augments the agility inherent in
the Model 2020. Particularly evident as an advantage over the use of even the GML
8x00 series separates, the ability to quickly change the relative position of the EQ and
Dynamics sections adds a great deal of versatility to the overall feature set.

Though the front panel EQ controls seem very intuitive to the initiated and experienced
audio engineer, the circuit design behind these controls is anything but simple and
straightforward. The Model 2020 EQ section features exemplary 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 Model 2020. 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.

It should be intuitive that since the Model 2020 Dynamics section front panel functions
are difficult to understand, so the unique circuit design behind these controls must be
incredibly complex. From the exemplary buffering circuits and proprietary discrete VCA
to the heart of the unit--the control circuitry--the Dynamics section maintains the power
and flexibility that is expected of GML units.
