Dual 15 Band Graphic Equalizer

The dbx 1215 equalizer was precision engineered to provide years of maintenance-free operation. 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 planned to ensure compatibility for all installations.

Product Description

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..

    Features
  • Switchable boost/cut ranges of ±6 or ±15 dB
  • Electronically balanced/unbalanced inputs
  • Servo balanced/unbalanced inputs
  • 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
