Proffesional DBX 2231 Dual 31-Band Graphic Equalizer with Type III Noise Reduction and PeakPlus Limiter

The DBX 2231 is a professional-grade, high-performance audio signal processor designed for live sound reinforcement, studio recording, and permanent installations. It combines a pristine dual-channel graphic equalizer with integrated dynamics processing, making it a staple in professional audio racks worldwide.Audio Precision and EqualizationThe unit features two independent channels, each equipped with 31 ISO-standard 1/3-octave sliders covering the human hearing range from 20 Hz to 20 kHz. It provides switchable boost/cut ranges of either ±6 dB or ±12 dB, giving audio engineers the flexibility to make either highly precise tonal adjustments or broad, corrective frequency sweeps. The sliders are center-detented for a true 0 dB flat setting.Integrated Dynamics & ProcessingType III Noise Reduction: This advanced proprietary system significantly improves the signal-to-noise ratio by up to 20 dB at the push of a button, keeping the audio path remarkably quiet even under heavy boost configurations.PeakPlus Limiter: Each channel features a dedicated limiter with an adjustable threshold from 0 dBu to +24 dBu. This circuit safeguards downstream amplifiers, drivers, and speakers from clipping and sudden signal spikes.Low-Cut Filter: A switchable 40 Hz low-cut (high-pass) filter on each channel attenuates unwanted low-frequency stage rumble, wind noise, and microphone handling vibrations.
