Dual Channel 31 Band Equalizer

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. The visionary design of

the dbx 12 Series makes your job easier.

The dbx 12 Series Equalizers were precision engineered to provide years of maintenance-free

operation in any application. The magnetically isolated transformer electronically

balanced/unbalanced inputs and servo balanced/unbalanced outputs RF-filtered inputs and outputs

and power-off hard-wire relay bypass with 2 second power up delay were steps our engineers took to

ensure compatibility for all installations. Only the best components were utilized yielding a 10Hz to

50kHz frequency response greater than 90dB SNR (ref +4dBu) less than 0.005% THD +Noise (1kHz at

+4dBu) and interchannel crosstalk of less than -80dB from 20Hz to 20kHz. All this attention to detail is

contained in a 2U steel/aluminum chassis. It’s no wonder that dbx has been a leader in the industry for

over 25 years.
