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.

Besides the traditionally superb Lab.gruppen sonic performance, fP3400 offers a full line
of important features:
Regulated switch mode power supply Today
There are many lightweight, switch-mode amplifiers in the market. However, the unique
Lab.gruppen switch-mode power supply technology offers a number of essential advantages
that make it superior to other and seemingly similar power supply designs. The most
important features are the regulated power supply and the extreme power efficiency. The r
egulated power supply easily deals with a very high variation in the AC mains voltage:it
can drop by up to 20% below its nominal level ? e.g. to 180 V instead of 230 V ? without
any problem. Perhaps even greater benefits result from the extreme efficiency of Lab.gruppen
amplifiers: only a fraction of the energy from the AC mains is turned into heat.
A regulated power supply also presents some other sonic advantages, such as better cone
control and the same fast response as a conventional power supply.
Multiple positions Gain switch
To meet the demands for a flexible gain structure in the system, Lab.gruppen offers a multiple
position gain switch. The maximum amplifier gain can be set to all industry standards: 20, 23,
26, 29, 32, 35, 38 and 41 dB.
Sophisticated protection circuitry, combining:
DC protection; protects against infrasonic signals.
VHF protection; protects the loudspeakers against strong very high frequency non-musical
signals above the audible range.
Thermal protection; prevents the amplifier from being overheated. The protection indicators
on the front panel are switched on, as a warning, before the protection process is initiated.
AC protection; shuts down the power supply if the line voltage is outside the operating voltage.
Clip limiter; prevents severely clipped waveforms from reaching the loudspeakers, whilst
maintaining full peak power. |
This professional stereo power amplifier, working in class-H mode, provides 2x1600W, at an efficiency of around 85%.
A massive transformer based power supply and hand selected components makes this power rating possible with exceptional audio quality and absolute reliability, even in the 2 Ohm mode.
The output stage is fully protected against over-temperature, short circuit, RFI and equipped with soft start circuit and temperature-controlled fan cooling.
The integral soft clip limiter protects against damage to the connected loudspeakers.
The activity of a protective circuit, signal and limiter is shown for each channel by LEDʼs.
