GML 2032

The Model 2032 Microphone Preamplifier / Parametric Equalizer is a single-channel, multi-input device for high-resolution studio and remote applications.

Incorporating the renowned 8300 preamplifier and reference-standard 8200 equalizer, the Model 2032 inherits over thirty years of GML engineering excellence.

This transparent class-A discrete design with internal supply delivers reliability, musicality, and precision.

GML 2032 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) lownoise,
  • 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
  • Flexible routing: Single-Channel, Independent, Inline Insert configurations
  • High-pass Filter; selectable 40 Hz, flat, 100Hz
  • Front panel Phantom and Phase illuminated switches
  • Front panel EQ IN and Insert illuminated switches
  • Overload (OL) indication LED
  • Power status LED
  • Low-noise, highly regulated internal linear power supply
  • Modern surface-mount construction, yielding maximum precision,
  • manufacturability, and reliability
  • No internal signal interconnects; high-quality signal relay switching
  • Carbon-film and conductive-plastic custom precision potentiometers,
  • manufactured to GML exacting standards
  • Multi-colored knobs, GML standard
  • Stylish and durable black-anodized aluminum front panel
  • Rugged chassis; black powder-coat finish over aluminum
  • Reverse-anodized front panel legend, much more permanent than ink or
  • paint processes
  • Baked-on epoxy paint silkscreen rear panel legend
  • Quality PCB manufacturing, assembly, and chassis construction
  • Specifications
