DC Fan
The built in DC fan has a continuous variable speed. Its control circuit monitors the temperature
of the output devices and the temperature of the power supply. The speed of the fan is calculated
out of this information. This system ensures that the fan always runs at optimum speed and
thus produces less noise.
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 reproduction.
EFN
Through the internal EFN circuit, with plug-in modules, extra functions can be added to the
amplifier, like cross-over, high- low- or band-pass filtering, equalization and loudspeaker
protection. Special protection boards are available for all Stage Accompany loudspeaker
systems. The installation of an EFN module needs to be done by an authorised Stage
Accompany service centre.
Soft Start
The soft start circuit is active when the ES 10 is turned on. The mains inrush current, which
normally is in excess of 50 A is limited to a safe value. However, take care not to switch on too
many ES 10 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.
