No two rooms sound the same. Ensure youll get a great sound whatever the sonic environment with a dbx 231s Dual 31-Band Constant Q Graphic EQ. Youll have granular control of your sound thanks to the 31 bands per channel offering ±12 dB. Get startling audio clarity with less than 0.003% total harmonic distortion. Youll be able to shape your sound without adding any extra noise. For wider adjustments you can set the adjustment range to ±12dB or for more precise changes you can change it to ±6 dB. High quality components for excellent results The 231s gives you two 31-band channels of 1/3-octave equalisation with 20mm nonconductive sliders and an intuitive user interface with output level metering. Built from quality components with meticulous attention to detail it offers an extended 10Hz to 50kHz frequency response with a 112dB dynamic range plus a switchable +/-6dB or +/-12dB boost/cut range. The unit has XLR and TRS inputs and outputs for flexibility in setup. The 231s is ideal for use in the studio on tour or in fixed installations.
