The dbx® 2-Series Graphic Equalizers have been designed to meet the needs of the most demanding sound reinforcement environments, while offering the simplicity of straight forward controls. The 215 not only provides standard features like dual channels, 15 2/3 octave bands, ISO frequency meters, +/- 12dB input gain range, and switchable 50Hz/12dB octave low-cut filters, but also includes other thoughtful features. These features include: 20 mm faders; selectable +/-6dB or +/-12dB boost/cut range for precise gain adjustments; XLR, and 1/4" TRS connectors for installation ease; balanced inputs and outputs for quiet operation; and chassis/signal ground lift capabilities for quick hum isolation. The visionary design of the dbx® 2-Series has been pursued to make your job easier. Two 15-band, 2/3-octave Constant Q frequency bands Switchable boost/cut ranges of ±6 or ±12 dB 12dB per octave, 3dB down @ 50Hz low-cut filter Front panel bypass switch ±12 dB input gain range 4-segment LED ladders for monitoring output levels XLR and TRS Inpts and Outputs Internal Toroidal Transformer Frequency Repsonse of 50kHx Dynamic range of greater than 108dB

With a lineage extending back to the revered 12 and 20 Series graphic equalizers, the dbx® 231 easily lives up to the dbx reputation at a price point which can find a home in the tightest of budgets. Besides including two 31-band channels of 1/3-octave equalization, the 231 also offers ±6 or ±12 dB boost/cut range; XLR, 20mm faders and 1/4" inputs; nonconductive nylon sliders; and an intuitive user interface with comprehensive output and gain reduction metering. As always, the inevitable result of our meticulous attention to detail and top-quality componentry is exceptional sound, performance, and reliability.Two 31-band, 1/3-octave Constant Q frequency bands Switchable boost/cut ranges of ±6 or ±12 dB 12dB per octave 50Hz low-cut filter Front panel bypass switch ±12 dB input gain range 4-segment LED ladders for monitoring output levels XLR and TRS Inpts and Outputs Internal Toroidal Transformer Frequency Repsonse of 50kHz Dynamic range of greater than 108dB
