The 160A offers such time-tested features as switchable OverEasy® and hard knee compression, extremely wide threshold ranges, and controls for ratio and output gain. The 160A also includes true RMS level detection, providing the most transparent dynamics processing available–from smooth, subtle compression to “brick wall” peak limiting. Its electronically balanced output stage is an outstanding driver for long cable runs (an output transformer is optional).With its unique “INFINITY +” inverse-compression mode, the 160A actually decreases the audio output level below unity gain when the input exceeds threshold. You can even stereo-couple two 160As to process a stereo mix without shifting the left/right image.The dbx 160A has truly redefined the standard for dynamics processing.
