Soft Start
The soft start circuit is active when the BB35 is turned on. The mains inrush current, which
normally is in excess of 60 A is limited to a safe value. However, take care not to switch on
too many DS20 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.
