The fP 6400 is a lightweight and space-saving power amplifier
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.gruppen’s Class TD amplifiers do not need this filter and this is one
reason why the Lab.gruppen Class TD obtains the same sonic quality as a traditional Class AB amplifier.
Besides the traditionally superb Lab.gruppen sonic performance, fP6400 offers a full line of important features:
