The GML Model 2032 Microphone Preamplifier / Parametric Equalizer is a single-channel, multi-input device for high-resolution studio and remote applications. Based on the reference-standard Model 8300 Transformerless Microphone Preamplifier and Model 8200 Parametric Equalizer, this flexible 1U processor continues the GML engineering tradition while bringing the utmost in transparency, detail, and musicality to an affordable, compact form factor.

The GML 2032 includes its own internal power supply.

GML Model 2032 Microphone Preamplifier / Parametric Equalizer 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
  • Flexible routing: Single-Channel, Independent, Inline Insert configurations
  • High-pass Filter; selectable 40 Hz, flat, 100Hz
  • Power status LED
  • Quality PCB manufacturing, assembly, and chassis construction
