The EAR 660 Fairchild-type valve limiter-compressor is designed to limit or compress the signal with the barest minimum of interference below threshold, and give the most subjectively satisfying operation on high-level signals. The unit has the standard range of attack and release times, making it easy to use.
Considerable effort has been spent optimizing the behavior around the "knee" of the attack/decay envelope and it is this that greatly contributes to the outstanding transparency and transient response that has made the EAR 660 the first choice of so many top audio professionals.
