dbx 131s is a single channel, 31 band, 1/3 octave graphic equalizer. The 131s includes ±12 dB input gain, switchable ±6 dB or ±12 dB boost/cut range, 20mm nonconductive sliders, an intuitive user interface, and output level metering. The 131s gives you exceptional sound and rugged reliability from its extended 10Hz to 50kHz frequency response and 110 dB dynamic range to the quality componentry and meticulous attention to detail.
Sure to find a home in the studio, on tour and with installed sound venues, the dbx 131s is destined to take its rightful place in the lineage of great dbx signal processors that are the professional’s choice in signal processing.
