dbx 1231 Dual 31-Band Graphic EQ - Secondhand

Full Description

High quality components for excellent results

The 1231 boasts 31 1/3-octave EQ bands with 45mm faders. Standard features include ISO frequency centres, +/-12dB input gain range and switchable 40Hz/18dB per octave low-cut filters. The unit also includes other insightful features, including selectable +/-6dB or +/-15dB boost/cut range for precise gain adjustments, balanced inputs and outputs for quiet operation and chassis/signal ground lift capabilities for quick hum isolation. With 1/4" TRS, XLR and barrier terminal strip inputs and outputs, the 1231 has the flexibility to accommodate your particular setup requirements.
