LAB GRUPPEN fP 6400 DIGITAL S.M.P.S 2X2300W 4ohm

High-tech in professional amplification!

fP amplifiers are extreme in every aspect, and loaded with Lab.gruppen's leading technology,
proven since many years: The super-efficient switch mode power supply - Lab.gruppen's
proprietary design - reduces the weight without any effect on the audio signal, resulting in
brilliant sound quality from the extreme lows to the very highs even under extreme, very difficult,
conditions.
“The coolest power amps you can find“, thanks to the Intercooler, a unique cooling system,
enabling both safe long-term operation, even when driven to the limits, and improved sound quality
at high levels.
The MLS feature lets the user "convert" any amplifier, as simple as it looks, into the perfect
drive engine for the individual load impedance, high or low, providing the best possible control
of the loudspeaker cones.
The flagship models, fP 6400 and fP 3400, incorporate the quantum leap in amp design:
Class TD, Lab.gruppen's evolution of the common class D. They offer the high efficiency of class D,
whilst avoiding all the usual drawbacks. Lab.gruppen simply sets a new standard! A complete and
reliable protection circuitry is a must, and all Lab.gruppen amps include the ALS short circuit
protection in their protection system.
All in all, the fP models are the reliable high quality companions both "on the road" and when
permanently installed. Simply the best trouble-free investment you can make!

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:

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 regulated 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.

The E Series is a range of lightweight, high-power switch mode amplifiers designed to the highest standards of reliability and sound quality. Developed for the touring market, E Series retain the sonic integrity of the benchmark MC and T Series amplifiers, without the physical weight.

The switch mode power supply is capable of delivering high peaks without any perceptible bass 'sag' at very low distortion and is kept within its safe operating area by the new, sophisticated MC² Audio 'intelligent' limiter. The E15, E25, E45 and E4-75 feature MC² Audioʼs proprietary current driven output stages for ultra-high definition sound, delivered over the entire audio bandwidth.

The E90 and the E100 are Class D amplifiers designed to meet the demands for higher power with increased efficiency whilst still maintaining the renowned MC² Audio sonic qualities and unsurpassed reliability.

All MC² Audio products are covered by a 5 year warranty.
