Lab Gruppen FP3400 is designed to deliver exceptional performance and quality, ideal for professional and personal use.
The fP 3400 is a lightweight and space-saving power amplifier, ideal for use in
high quality touring sound systems as well as in demanding permanent installations.
Heat and cooling are fundamental problems in many extreme high power amplifiers
similar to the fP 3400.
In 1990, Lab.gruppen patented a high efficiency amplifier called fP 3400. This
development was an evolutionary step past the Class D amplifier. Lab.gruppen call
this unique step forward: Class TD. This stands for: Tracking Class D.
Class TD obtains the same high efficiency as Class D, while avoiding the main
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.
