Audiofrog HiFi Class-D amplifiers include a dual purpose heat sink that also acts as an EMI shield. The heat sink and the bottom plate are electrically connected to each other and to one of the internal PCB layers through a trace that runs the perimeter of the board on the top and on the bottom. Combining the sink, the bottom panel and a PCB layer help to minimize EMI (electromagnetic interference) emitted from the amplifier, which prevents degradation of the radio's FM reception.
