The 560A offers a classic hard knee compression and OverEasy mode – that’s dbs’s soft knee mode. It incorporates dBx’s program-dependent attack and release times.

It is a natural sounding dynamic processor with a wide-ranging threshold, ratio and output controls and true RMS level detection.

Its “Infinity +” inverse-compression feature decreases the audio output level when the input exceeds the threshold beyond unity gain, which is useful in live settings when you need to control mix levels of extremely loud signals.

At an affordable price, the 560A gives you broad range compression options to use for recording different instruments.
