The 31 bands feature 45mm sliders with center detent and 6dB or 12dB of boost or cut. It comes equipped with ART's FDC (Feedback Detection Circuitry), which visually indicates potential feedback on the EQ band's LED, letting users quickly bring down that band. The Constant-Q filtering ensures changes on one band do not affect the adjacent frequency bands. Each channel features both high and low pass filters and a master level control in addition to the individual bands. Use the EQ with unbalanced RCA or balanced XLR or TRS with both inputs and outputs of each type. You'll find the HQ231 an indispensable part of your live sound or in-studio setup.\u003c\/p\u003e\n\u003ch3\u003eHQ231 Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwo-channel 31-band graphic EQ\u003c\/li\u003e\n\u003cli\u003eFDC illuminates slider LEDs to indicate potential feedback immediately\u003c\/li\u003e\n\u003cli\u003eConstant-Q filter helps isolates individual bands\u003c\/li\u003e\n\u003cli\u003e45mm center-detent sliders\u003c\/li\u003e\n\u003cli\u003e6 or 12dB of boost or cut\u003c\/li\u003e\n\u003cli\u003eBalanced XLR\/TRS or unbalanced RCA inputs and outputs\u003c\/li\u003e\n\u003cli\u003eHigh and low pass filters for each channel\u003c\/li\u003e\n\u003cli\u003eVariable input level controls\u003c\/li\u003e\n\u003cli\u003eVU metering on each channel\u003c\/li\u003e\n\u003cli\u003eBypass on each channel\u003c\/li\u003e\n\u003cli\u003eGround lift switch\u003c\/li\u003e\n\u003cli\u003eSelectable input voltage\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ART","offers":[{"title":"Default Title","offer_id":47164253798656,"sku":"HQ231","price":110.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/7723\/4688\/files\/UsedArtHQ231Dual31-BandGraphicEqualizerfront.jpg?v=1761581086","url":"https:\/\/awesomeaudioplus.com\/products\/used-art-hq231-dual-31-band-graphic-equalizer","provider":"Awesome Audio Plus","version":"1.0","type":"link"}
