text: A universal switched-mode power supply (100 to 240 volts) ensures that the KH 80 DSP works in any country and is immune to fluctuations in the mains supply. The internal signal chain of the KH 80 DSP is completely symmetrical, which minimises any noise caused by external electromagnetic interference. Also, the electrical design is double-insulated so that ground loops are impossible. When the monitor is not in use, an auto standby mode saves energy.
