Housed in a rugged 3U steel chassis, this unit combines comprehensive equalization control with built-in Type III noise reduction and PeakPlus limiting, offering engineers a powerful all-in-one solution for system tuning and signal management. Each channel features 45mm center-detented sliders with selectable boost\/cut ranges of 6dB or 15dB, allowing for either subtle corrective equalization or broad tonal shaping.\u003c\/p\u003e\n\u003cp\u003eThe integrated Type III noise reduction provides up to 20dB of dynamic noise reduction at the push of a button, significantly improving signal-to-noise performance without compromising audio quality. The PeakPlus limiter section includes front-panel 41-detent rotary threshold controls with four-LED gain reduction metering, offering transparent protection against transient peaks with a threshold range from 0dBu to +24dBu. Additional features include switchable high-pass filters, variable input level controls with clip indicators, and comprehensive connectivity via balanced XLR, 1\/4-inch TRS, and barrier strip connections. EQ bypass switches with LED indicators per channel enable instant comparison of processed and unprocessed signals, while the internal power supply and all-steel construction ensure reliable performance in demanding environments.\u003c\/p\u003e\n\u003cp\u003eThis unit is being sold as-is and requires repair. Based on common issues documented with the 2231 model, the unit exhibits intermittent signal loss on one channel requiring hot signal levels to engage, a problem frequently traced to poor connections at the input jacks, failing solder joints, or loose ribbon cable connections between the I\/O board and main circuit board. The 1\/4-inch input jacks are known failure points, with their switching components prone to shorting out over time, though some users have reported success with contact cleaner or reseating internal connectors. The unit also shows visible wear including scratched front panel, several sticky or slow-responding slider faders, and one bent rack ear. Due to these documented issues and physical condition, this dbx 2231 is offered as a repair project or for parts, ideal for technicians familiar with common dbx failure points.\u003c\/p\u003e","brand":"AVGear.com","offers":[{"title":"Default Title","offer_id":46310319390919,"sku":"1942-350","price":60.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/7865\/6199\/files\/DBX2231DualChannel31-BandGraphicEqualizerLimiter_NEEDSREPAIR_-1.jpg?v=1773657722","url":"https:\/\/www.avgear.com\/products\/dbx-2231-dual-channel-31-band-graphic-equalizer-limiter-needs-repair","provider":"AVGear.com","version":"1.0","type":"link"}
