Remaining Cool
To say that amplifiers get hot is an understatement. Anyone
who has ever used one knows all too well that heat is an
amplifier’s worst enemy. Drive most amplifiers hard for very
long and they will overheat, resulting in thermal protection:
they either cut back power, quit working during the middle of
a show or blow up altogether.
With heat being a potentially
big problem, Lab.gruppen
approached the problem by
developing simple solutions
for a complex set of problems.
First, and rather than just man-
aging the heat, Lab.gruppen
chose a path that reduces the
amount of heat generated in
the first place.

Intercooler®: This is Lab.gruppen’s ultra-efficient compact
cooling system. At the heart of the Intercooler® system is the
unique pure copper heat sinks. Optimized for maximum surface
area and greater air turbulence, they offer far superior heat
dissipation than traditional aluminum designs. Complimenting
the pure copper heat sinks are speed-controlled fans that force
air through the heat-sinks front to rear. All output transistors
receive the same cooling effect, as they are all positioned
perpendicular to the flow.
As a result of this technology, Lab.gruppen is able to develop
a product that packs the greatest amount of power in a chassis
sized smaller than ever thought possible.

The Weight Loss Program
Some call their amplifiers lightweight but we consider
Lab.gruppen amplifiers to be the benchmark of lightweight.
Losing weight without side effects is an art, and at Lab.gruppen
our engineers fully understand this art.

6400 W and only 22 lbs (10 kg): Our most powerful amp, the
fP 6400, delivers 6400 watts with ease, is just 2U high, only
14” (347 mm) deep and weighs a mere 22 lbs (10 kg).

Ultimate Touring Amp:
Lab.gruppen fP Series amplifiers are so light and efficient that
their compatibility for touring applications is unsurpassed.
Even in the harshest of environments, they keep on performing
making them the perfect solution for permanent installed
systems as well.

The Convertible Power Amplifier
Wouldn’t it be great if you could tell an amplifier how to match
its output to the load it will see? Certainly, it makes a big dif-
ference to the amplifier if the speaker impedance is 16

or something in between.
Matching Load System (MLS™): Usually the average amplifier
is under much greater stress when driving a low impedance
load, such as 2

A typical problem: If an average
amplifier delivers a maximum output
voltage of 100 V and a maximum output
current of 12 A to an 8
amplifier delivers a maximum output
voltage of 100 V and a maximum output
current of 12 A to an 8
Ω loudspeaker, this equates to 1200
watts in output power. If a second speaker is added in parallel,
the impedance drops to 4
the impedance drops to 4
Ω and the amplifier will try to provide
double the current, 24 A. If the amplifier does not have an ade-
quate power supply capability then stress is placed on the
system. As the amplifier continues to try and provide current
beyond its limit, it will run hotter and hotter, then the signal
will distort and eventually thermal shut down will follow.

The Lab.gruppen solution, Convertible Power: With most
fP models* you will find MLS™. The MLS™ is accessed via a
set of rear panel switches. The output voltage may be
reduced in fixed increments to accurately match known loads.
When engaged the voltage/current ratio is “converted”.
MLS™ reduces the output voltage of the amplifier increasing
its ability to deliver more current and provide the same output
power for different loads.
Take the equation in the
above example: 100 V x 12 A
= 1200 W may be converted
to 80 V x 15 A = 1200 W, or
55 V x 22 A = 1200 W.

The great benefit of MLS™
with its unique ‘Constant
Power Conversion’ is that at
low impedances the overall
efficiency is improved. The
amplifier operates cooler and
is unlikely to run into protec-
tion. The most important
result of this is that it just sounds much better.

MLS™ also permits output power management. This enables
the amplifier to be used in several applications. An amplifier in
the fP Series may be configured to prevent smaller speakers
or HF drivers from being over-powered. For example, a single
amp can now be properly configured for a bi-amped floor
monitor speaker system. The same amplifier could then be
