The 500 Series 560A Compressor/Limiter from DBX offers VCA-based compression with the switch-selectable OverEasy and Hard Knee compression curves.

With a wide-ranging threshold, ratio and output controls and true RMS level detection, this compressor provides natural-sounding dynamics. The 560A will provide much needed punch to drums, bass, vocals and also subtle compression to "brick wall” peak limiting.

Choose low ratios and OverEasy compression to expertly smooth out fluctuating vocal and instrumental levels, or use the 560A's Hard Knee compression and high ratios for protection against overload distortion in digital recording, P.A. systems, and broadcast signals.

The 19-segment, switchable Input/Output LEDs and 12-segment Gain Reduction LEDs provide precise analysis at a glance. And, the INFINITY+ inverse-compression mode actually decreases the audio output level below unity gain when the input exceeds threshold, correcting overbearing vocal choruses and controlling runaway mix levels.
