ENGLISH Q™ SERIES EQUALIZERS Thank you for purchasing a Peavey Electronics Q Series graphic equalizer. The Q family features one dual-channel model (Q2151) and one single-channel model (Q1311), both incorporating Peavey’s legendary low noise, low distortion design. These ruggedly constructed Q Series EQs have 20 mm, center-detented control sliders enclosed in metal for durability.
EQUALIZATION PROCESS Always begin the equalization process with all sliders at their center-detent (flat response) positions. Lower each fader until the feedback frequency is found. Lower the faders in small amounts to avoid adversely affecting sound quality. Likewise, excessive boosting of a frequency may result in feedback. EXERCISE CAUTION WHEN ATTEMPTING TO BOOST FREQUENCIES BELOW SPEAKER SYSTEM TRANSDUCER CUT-OFF.
