The Emitter I is the entry model, offering all the qualities of the Emitter family. Separate power supply is keeping electro-magnetic fields and vibrations away from the control unit. The power supply unit is equipped with two large and powerful PM (Philbert-Mantelschnitt) transformers with a smaller PM transformer for Standby operation. The two power transformers are switched OSwisscables softly with 5 high power relays in the energy saving mode. If required, they can be switched via a current limiter into normal operation mode. In the power supply unit, 8 different voltages are generated. Every voltage is rectified individually and pre-buffered. These voltages are used to supply the input amplifier, driver, output stage as well as the control circuit separately.
