Four To The Floor

Designed for the ever-changing modern recording environment, dbx have recognised the increasing multiple-channel demands of recording studios and music professionals alike - remedying it by introducing their own studio-ready, rack-mountable unit with multiple channels of high quality, easy to use compression.  

DBX 1046 Quad Compressor Limiter Features:

• Four independent channels of operation
• Stereo linkable in two pairs
• PeakStopPlus limiting control
• Independent Threshold and ratio controls
• Switchable OverEasy or Hard Knee compression
• Classic dbx compression
• 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
• Dual True stereo or quad mono operation
• Switchable +4dBu or -10dBV operation per channel

Classic dbx, Modern Package

Incorporating the industry standard dbx design, the 1046 delivers pristine sonic quality combined with that classic dbx sound. From OverEasy to hard knee compression, you'll find the settings perfectly suited to your needs and taste.

Ideal for use on individual tracks or linked up to a multitrack recorder, the 1046 Quad Compressor can be used for any application, with independently configurable settings per channel, allowing for individual settings to run simultaneously.

Complete with the newly developed PeakStopPlus feature, you can be assured that any dangerously high peaks will be captured and tamed, protecting both your valuable equipment and your invaluable hearing.
