Description

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.

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

Why We Like This

The long-throw faders and clearly labeled frequency bands make corrective EQ fast and intuitive, which is especially valuable when tuning a system under time pressure.
