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
