为不间断运行而设计
Powersoft’s DSP implements a complete audio management system that provides a unique level of control and can be used to set the tone of any space.
Our current line of amplifier offers Dante™ either as standard or as an option on any model, for audio over IP networking.
Powersoft has always been very focused on energy saving and the use of the Power Factor Correction (PFC) has been a trademark for improving performance and containing mains current draw and consumption.
In any amplifier output stage, the efficiency is a function of the difference in the output voltage delivered to the load and the rails voltage delivered from the power supply.
Power Sharing enables part of the power to be shared across all output channels so that it can be used where it is needed the most.
With modern systems growing larger in size, the resistance that is added by lengthy cable runs starts to become an issue.
