Since I haven't the power supply with dc protection I added output capacitors to my modules, but now turn on and turn off transient are louder than before. The system is multiamplified so I used 47mf for the amp that goes from 300hz up , 10mf for 1000hz up and 4,7mf from 5000hz up. The noise is evident even in the tweeters amp where the cap is only 4,7mf.Does this mean that this capacitor is in conflict with Ucd technology?
