gml gml2032 Manual De Usuario
The Model 2032 Microphone Preamplifier / Parametric Equalizer offers exceptional
flexibility and sonic accuracy when dealing with a variety of signal sources and
conditions. Allowing quick adjustment of any critical parameter, the operation of the
Model 2032 remains straightforward despite an extensive feature set. Indeed, a
reduction in apparent complexity is achieved by taking a building-block approach to
operational analysis.

I. Preamplifier
The preamplifier section of the Model 2032 Microphone Preamplifier / Parametric
Equalizer is based on the gain stage of the Model 8300 Transformerless Microphone
Preamplifier, though there are some design changes and a few additions to expand its
capabilities further than is realized in the highly specialized Model 8300 mic preamp.

Two input formats are accommodated on the Model 2032: an Input XLR connector is
provided on the back panel for microphone input, while the front panel sports a 1/4"
unbalanced musical instrument connector. Input signal selection is determined by the
Source toggle switch.

The microphone input of the Model 2032 is an exact copy of the Model 8300 input
circuitry, complete with 48V phantom power and subsequent 2-pole phantom filter.
Unlike the Model 8300, the phantom power switch is conveniently located on the front
panel and is illuminated to warn the user that phantom power is ON. The MIC input is
precision electronically balanced, 1kΩ nominal input impedance, with tremendous
dynamic range, remarkably low noise, fast slew rate, and wide bandwidth.

Adding to the Model 2032 input options, the front panel MI input extends the sphere of
application to the realm of the oft-neglected musical instrument. This high impedance
unbalanced input (1MΩ nominal) offers low noise and low distortion, plus a wide
dynamic range and ruler-flat extended frequency response to outclass common
instrument inputs. Especially useful for recording bass or electric guitar, this input can
also be used for a variety of other unbalanced sources such as electronic keyboards,
samplers, etc.

As previously mentioned, the input signal for the Model 2032 is selected on the Source
switch, located near the left corner of the front panel. Only one source may be active
through the channel at a time; however, signals may be present at the other inputs
since the source select function does not ground unused inputs

. Phantom powering may remain On, if necessary, when
switching between input sources without damage to other input devices since the
phantom supply does not reach the or MI input. It is, however, recommended that the
phantom power be turned Off when not in use to preserve power supply efficiency and
eliminate possible DC pops when changing input source selection.
