  • DBX 1231 31-Band Equalizer - Ex Display - Last One! Details

    The dbx 12 Series were designed to meet the needs of the most demanding sound reinforcement environments, while offering the simplicity of straightforward controls.

    The 1231 provides standard features like dual-channels, 31 1/3 octave bands, ISO frequency centers, +/- 12 dB input gain range, and switchable 40Hz/18 dB per octave low-cut filters, but also includes other insightful features.

    These include 45 mm faders; selectable +/-6dB or +/-15dB boost/cut range for precise gain adjustments; XLR, barrier strip, 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.

    Features

    • Switchable boost/cut ranges of ±6 or ±15 dB
    • Electronically balanced/unbalanced inputs
    • Servo balanced/unbalanced outputs
    • RF filtered inputs and outputs
    • XLR, Barrier Strip, and 1/4" TRS connectors
    • -12dB/+12dB input gain range
    • 18dB/octave 40Hz Bessel low-cut filter
    • Chassis/signal ground lift capability
    • Internal power supply transformer
    • Power-off hardwire relay bypass with 2-second power-up delay.
