The solid state power broadcast amplifiers are designed in SMD technology and operate in class A mode. All power transistors are current stabilized, in order to guarantee a stable working point.
Two fans take care of the cooling. For that reason the amplifier can be operated up to ambient temperatures
of + 50 °C. A temperature control switches off the complete amplifi er in case of overheating. After cooling down the amplifier will be restarted.
A green LED indicates the operating voltage.
- class A operation
- temperature control
- big temperature range of 0-50 °C
- excellent amplitude-frequency response
