dbx 560A

The DBX 560A Compressor/Limiter brings legendary VCA-based compression into the popular 500 Series format, continuing the tradition of excellence established by DBX’s modular processors. Here’s a detailed overview of its features and specifications:

Features:

1. OverEasy® or Hard Knee Compression: Offers switch-selectable compression curves for versatile dynamic control, with ultra-musical program-dependent attack and release times.
2. Wide-Ranging Controls: Extensive threshold, ratio, and output controls allow for precise adjustments tailored to various audio sources.
3. True RMS Level Detection: Provides accurate and natural-sounding dynamics processing.
4. Infinity+ Compression Mode: Unique mode that decreases the audio output level below unity gain when the input exceeds threshold, useful for controlling excessive levels.
5. Input/Output Meter Displays: 19-segment, switchable LEDs for precise analysis at a glance, ensuring optimal setup.
6. 12-Segment Gain Reduction LEDs: Offers clear visual feedback on gain reduction levels.
7. Versatile Application: Suitable for anything from subtle compression to aggressive peak limiting, applicable to drums, bass, vocals, and more.
8. Program-Dependent Attack and Release Times: Ensures optimal compression characteristics tailored to the input signal.
9. Selectable OverEasy® or Hard Knee Threshold Characteristic: Provides flexibility in compression behavior.
