The dbx®12 Series graphic equalizers 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, thirty-one 1/3 octave bands, ISO frequency centers, +/- 12 dB input gain range, and switchable 40 Hz/18 dB per octave low-cut filters, but also includes other insightful features. These include 45 mm faders; selectable +/-6 dB or +/-15 dB 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 dbx's engineers took to ensure compatibility for all installations. Only the best components were used, yielding a 10 Hz to 50 kHz frequency response, greater than 90 dB SNR (ref +4 dBu), less than 0.005% THD +Noise (1 kHz at +4dBu), and interchannel crosstalk of less than -80 dB from 20 Hz to 20 kHz. All this attention to detail is contained in a 3U steel/aluminum chassis.
