A 500 module compressor/limiter based on the traditional 160A. Of course, it also has OverEasy/Hard Knee characteristics switching. It is a traditional compressor that allows for an extremely wide range of parameter settings and can be used in any situation.
■Compressor/Limiter API500 module
dbx 560A is a VCA based compressor. Like the dbx 160A, it has OverEasy and Hard Knee curves. Extremely wide thresholds, ratio and output controls, and RMS level detection provide natural-sounding dynamics processing that adds punch to drum, bass, and vocal sounds.
■Main features
・OverEasy or hard knee compression with dbx supersonic program attack and release times
・Compression ratio: 1:1 to infinity:1 to -1:1
- Accurate RMS gain reduction and input/output meter display with calibration control for various operating levels
・RMS level detection
・Compression using Exclusive Infinity + negative ratio
