DDC
DDC (Dynamic Damping Control) is a special way of measuring the cone movement of a
loudspeaker. The voltage induced in the voice coil is sensed and fed back to the amplifier’s
feedback circuit. Hence, a virtually infinite damping is achieved, which results in an exceptionally
tight sound production.
Soft Start
The soft start circuit is active when the HE50 is turned on. The mains inrush current, which
normally is in excess of 100 A is limited to a safe value. However, take care not to switch on
too many HE50 amplifiers at the same time, or you risk that the main fuses of your distribution
may trip.
Temperature, DC, HF and Short Circuit Protection
The amplifier and the loudspeakers are protected against all possible damages.
