Beskrivelse
Heat and cooling are fundamental problems in extreme high power amplifiers such as the fP 6400. Already in 1990, Lab.gruppen patented a high efficiency amplifier, in fact an evolution of the Class D amplifier. Lab.gruppen therefore call it Class TD. It obtains the same high efficiency as Class D, but avoids its drawbacks. Class D has a power-amplifier topology using Pulse Width Modulation (PWM) to achieve high efficiency, but it needs a recovery
filter between the output stage and the loudspeaker. Lab.grup
