dbx 231s is a dual-channel 31-band graphic equalizer featuring 20mm non-conductive sliders that can be set to either +/-6dB or +/-12dB of boost or cut. A global control gives you +/-12 dB of input gain. A 12dB per octave, 3dB down at 50Hz low-cut filter can also be switched in if required. The 231s provides exceptional sound and rugged reliability that guarantees you will always sound your best, from its extended 10Hz to 50kHz frequency response and 112 dB dynamic range to the quality componentry and meticulous attention to detail.
