    Parameter related to the transient response of the control circuit are important for distortionfree processing. These time constants are allways adaptive controlled without remarkable limitation of parameter range. This is caused by the presence of transient pulses in allmost operation manual b40, chapter 2 -Function description- page 2-5...
