DBX 12 Series - Dual 31 Band Graphic Equalizer 1231

DBX 12 Series - Dual 31 Band Graphic Equalizer 1231

The 1231 is dual channel designed by DBX, 31 band 1/3 octave graphic equalizer. The DBX 1231 was designed for meeting the needs of the most demanding sound reinforcement environments, while offering the simplicity of straightforward controls.

The DBX 1231 has sliders which are 45mm center detent, with two selectable boost/cut ranges for precise gain adjustments. The unit is also featured with the high pass filters with bypass, active balanced input and output connections, chassis/signal ground lift capabilities for quick hum isolation and an internal power supply. Multiple input & output configurations are present for the ease of use. The XLR & 1/4" TRS connectors use active balanced, low noise circuitry, along with the barrier strips.

The DBX 1231 was precision engineered for providing years of maintenance-free operation in any application. The magnetically isolated transformer, RF-filtered inputs and outputs, and power-off hard-wire relay bypass with two second power up delay, guarantees compatibility with all types of installations.
