About DBX

The dbx 1066 dual mono/stereo compressor/limiter with gate carries both the classic dbx response, in addition to full manual control over the attack and release characteristics. Frequency dependent gain control is easy to set up and execute with the side chain and the Side Chain Monitor button helps with setting up the required EQ.

The contour switch allows entire mixes to be easily smoothed with soft compression, while keeping low frequencies from punching holes in the overall mix. Selectable input and output metering provides information to help match equipment level-wise, maximizing signal-to-noise ratio. For overall speaker protection, PeakStopPlus represses unwanted transients that could blow drivers, while minimizing the distortion common to many other hard-limiters. Selectable Hard-Knee or OverEasy characteristics make the 1066 ideal for gain control needs, whether for "heavy" almost-special-effects compression or soft, smooth gain leveling.

In the studio, broadcast facility, or on the road with a P.A. system, the 1066 is designed for simple operation. It allows the user to eliminate unwanted signals, control overall signal gain and guard the overall mix in dual mono or stereo operations.

DBX Features

  • Selectable auto (classic dbx) or manual (variable Attack and Release) compression
  • Contour switch removes unwanted low frequency information from detector circuit
  • Selectable Overeasy or Hard Knee compression modes
  • PeakStopPlus limiting for setting maximum allowable level with minimal distortion
  • SC Ext and SC Mon for setting up and monitoring external devices for gating function
  • True differentially balanced gold-plated XLR and 1/4" inputs and outputs
  • True RMS level detection
  • Precision metering of input level, output level and gain reduction
  • True stereo or dual mono operation
  • Switchable +4dBu or -10dBV operation per channel
