Combining the features of the GML flagship 8200 Parametric Equalizer and 8300
Transformerless Microphone Preamplifier, the Model 2032 embodies the legendary
detail and accuracy for which GML is renowned. The power and functionality of these
revolutionary processors is further coupled with the addition of a front panel musical
instrument input, two position high-pass filter, front panel phantom and phase switching,
and flexible routing options while maintaining the GML standard of performance and
transparency. These advanced circuits, envisioned by George Massenburg, have
benefited from over 30 years of research, limited manufacturing, critical listening
analysis, widespread usage by demanding industry professionals, and continuous
evaluation by the GML Engineering Department.
The GML Model 2032 Microphone Preamplifier / Parametric Equalizer derives its power
and flexibility in large part from its features:
•• All-discrete, Class-A design; no integrated circuits to compromise the
audio path
•• DC-servo and premium-grade film coupling; no interstage capacitors to
add distortion or degrade over time; no tantalum electrolytic, ceramic, or
aluminum electrolytic capacitors in the signal path*
•• Transformerless; precision electronically balanced inputs
•• Designed with GML 9202 (single) and GML 8501 (dual-differential) low-
noise, low-distortion, wide dynamic range, wide bandwidth precision
discrete opamps
•• DC-servo stabilized direct-coupled output
•• Multi-input format: MIC or MI (front panel musical instrument)
•• Wide gain range (10 dB to 75 dB) available on both inputs
•• Precision Gain switch: 65dB range in 5dB steps
•• Continuously variable preamplifier Fine gain control, +/-5dB
•• Four-band fully parametric equalizer
•• Low-frequency and High-frequency Shelf mode capability
